Do You Struggle With Contact Lens Comfort? Scleral Lenses May Be the Answer!

boy wearing a gray hoodie 640Most people are familiar with traditional soft lenses, which provide clear vision for those who are nearsighted or farsighted.

In certain cases, particularly for those with corneal irregularities or astigmatism, standard gas permeable (GP) lenses may be recommended. However, people with several eye conditions can’t tolerate standard GPs and find scleral lenses a much better, more comfortable alternative.

What are Scleral Lenses?

Patients with sensitive eyes or corneal abnormalities may benefit from custom-designed scleral lenses, which provide crisp vision and comfort thanks to their unique design.

Scleral lenses are usually recommended for those with keratoconus, severe dry eye syndrome, astigmatism or anyone who find it difficult or impossible to wear standard contact lenses.

Scleral lenses are large gas permeable lenses that vault over the cornea and rest on the sclera, the white part of the eye, instead of the cornea. This creates a new optical surface and prevents corneal irritation. Furthermore, a reservoir of pure saline solution between the back surface of the lens and the front of the cornea keeps the eye hydrated all day long.

Benefits of Wearing Scleral Lenses

Scleral lenses provide comfort, visual acuity and stability.

Stable Vision

With scleral lenses, you’ll experience continual clear vision. Because of their wide diameter, the lenses remain centered on your eye. Even if you play sports or lead an extremely active lifestyle, scleral lenses will stay in place and won’t easily pop out.

Long-Lasting Lenses

These gas permeable lenses are made of high-quality long-lasting materials. As a result, scleral lenses usually last between 1-2 years. While the initial cost of scleral lenses is higher than the cost of regular contacts, they give you more bang for your buck.

Safe and Easy-to-Use

Scleral lenses are easier to insert and remove from your eyes than regular GP lenses, thanks to their large size and rigid material. This also limits the risk of damaging your cornea while handling your lenses.

Comfort for Dry Eyes

It’s not uncommon for certain contact lens wearers to suffer from eyes that feel dry, red, itchy, uncomfortable, and at times very painful. Eye drops and artificial tears can deliver relief, but they are no more than a temporary solution.

One of the best contact lenses for optimal comfort and hydration are scleral lenses, as they simultaneously provide vision correction, protect the eyes, and lubricate them.

If you’ve experienced discomfort while wearing regular contact lenses, you may have keratoconus, irregular corneas, dry eyes or hard-to-fit eyes. Find out whether custom-designed scleral lenses are right for you by scheduling an eye exam at Dr. Nathalie Cassis today!

Scleral Lens and Keratoconus Center at Envision Ghent Optometry serves patients from Norfolk, Virginia Beach, Chesapeake, and Suffolk, Virginia and surrounding communities.

Frequently Asked Questions with Dr. Nathalie Cassis

Q: Can you sleep with scleral lenses?

  • A: It’s not recommended to wear scleral lenses while you sleep. Sleeping with your scleral lenses on can cause the tear layer behind the lens to become stagnant, thus increasing the risk of eye infections.

Q: Are scleral lenses more comfortable than standard gas permeable lenses?

  • A: Scleral lenses provide clear vision and long-term comfort for those with irregularly shaped corneas. This is due to their unique design that covers a wider area of the eye while avoiding direct contact with the cornea.

What’s a Chalazion?

What is a Chalazion 640Finding a lump on your eyelid can be scary, but it doesn’t have to be. Luckily, a chalazion isn’t a serious condition and is rather simple to resolve.

In most cases, a chalazion can easily be treated and will completely disappear following treatment. However, if non-invasive treatments don’t work, your eye doctor may need to remove it through an in-office surgical procedure.

At Dry Eye Center at Envision Ghent Optometry we can diagnose and help treat your chalazion so that you can see comfortably.

What is a Chalazion?

A chalazion, also known as a meibomian cyst, is a small fluid-filled cyst.

Eyelids contain meibomian glands, which produce oil to lubricate the surface of the eye. When one of these glands becomes blocked, it may cause swelling and lead to a small painless lump called a chalazion.

What Causes a Chalazion?

A chalazion occurs when the gland in the eyelid is clogged. Exactly why the gland becomes clogged isn’t known, but some individuals appear to be more susceptible to developing a chalazion than others.

A chalazion may be associated with dry eye syndrome, which is often caused by meibomian gland dysfunction.

People exhibiting certain risk factors are more likely to develop a chalazion. This includes people who have:

  • Blepharitis, an inflammation of the eyelids
  • Conjunctivitis, also known as pink eye
  • Thicker oil or meibum than normal consistency
  • Ocular rosacea, a skin condition adjacent to the eyes
  • Seborrhea, or dandruff, of the eyelashes
  • Styes or a history of styes

What Are the Symptoms of a Chalazion?

Common symptoms of a chalazion include:

  • A bump on the eyelid that sometimes becomes swollen and red
  • An entirely swollen eyelid, although very rare
  • Vision issues (such as blurred vision) if the chalazion becomes large enough to press on the eyeball

While a chalazion is not an infection, it may become infected. In the rare event that this occurs, it may become red, more severely swollen, and painful.

Chalazia are often mistaken for styes since they have a similar appearance.

What’s the Difference Between a Chalazion and a Stye?

It can be difficult to differentiate a chalazion from a stye.

Styes develop along the edge of your eyelid and can at times be seen at the base of an eyelash. In contrast, chalazia usually occur closer to the middle of the eyelid. A stye is more likely to be painful and tends to have a yellowish spot at the center that may burst after a few days.

Basically, the most noticeable difference between a chalazion and a stye is that a chalazion tends to be painless while a stye is usually painful and may cause the eye to feel sore, itchy or scratchy.

How to Treat a Chalazion

Most chalazia require minimal medical treatment and some may even clear up on their own in a few weeks to a month. When a chalazion first appears, you can try doing the following for 1-2 days:

  • Apply a warm compress to the eyelid for 10 to 15 minutes, 4 to 6 times a day. The warm compress helps soften the hardened oil that blocks the ducts, allowing drainage and healing.
  • Gently massage the external eyelids for several minutes each day to help promote drainage.

If the chalazion does not drain and heal within a few days, contact your eye doctor. Don’t attempt to squeeze or pop the chalazion, as it may inadvertently cause more damage.

To learn more about chalazion treatment and the other eye care services we offer, call Dry Eye Center at Envision Ghent Optometry to schedule an appointment.

Frequently Asked Questions with Dr. Nathalie Cassis

Q: Can a chalazion spread from one person to another?

  • A: Since a chalazion is not an infection, it cannot spread from one person to another or even to the other eye of the affected person.

Q: Can a chalazion affect my eyesight?

  • A: A chalazion doesn’t affect vision. In rare cases, if the lump is large enough to distort the ocular surface it can cause temporary astigmatism, blurring vision. However, vision will return to normal once a medical professional removes the chalazion or once it diminishes in size.

Can People With Dry Eye Syndrome Wear Eye Makeup?

Eye Makeup 640×350If your eyes feel dry and irritated after wearing eyeliner—you aren’t alone. Many patients report symptoms of dry eye syndrome after rocking a smoky eye look, especially for extended periods of time.

The good news is those makeup lovers who have dry eye syndrome can continue to put their best face forward with the guidance of their dry eye optometrist.

What is Dry Eye Syndrome?

Dry eye syndrome (DES) is a chronic lack of ocular hydration that can be caused by several factors, including genetics, environmental irritants, allergies, certain medical conditions, specific medications and hormonal fluctuations.

Symptoms of DES may include:

  • Burning eyes
  • Itchy eyes
  • Red or irritated eyes
  • Dry eyes
  • Watery eyes
  • Mucus around the eyes
  • Discomfort while wearing contact lenses
  • Light sensitivity
  • Blurred vision
  • Eyes that ache or feel heavy

DES treatment depends on the underlying cause of the problem. Your dry eye optometrist will thoroughly evaluate your eyes to find and treat the source of your symptoms.

Can Eyeliner and Other Eye Makeup Cause Dry Eyes?

Our eyes are lined with tiny glands, known as meibomian glands, at the edge of both the upper and lower eyelids that secrete nourishing oils into our tears to help prevent premature tear evaporation. Any blockages or irritation in these glands can lead to meibomian gland dysfunction (MGD), a leading cause of dry eye symptoms.

A recent study published in The Journal of Cornea and External Disease found that the regular use of eyeliner can cause the tear film to become unstable as the eyeliner can clog these small meibomian glands.

An important measurement, known as tear film breakup time, was much lower in the eyeliner-wearing group in the study, indicating that their tears evaporated more quickly. The same group also had reduced meibomian gland function and more symptoms of MGD.

The good news is that you can still wear eyeliner and other eye makeup products, despite having dry eyes. Here’s how:

Tips for Safely Wearing Eyeliner With Dry Eyes

  1. Only use eye makeup products that are intended for use around the eye area.
  2. Keep your makeup and applicators clean. Sharpen your eyeliner pencil and clean your brushes before each use to avoid contamination.
  3. Replace your eye makeup as often as recommended by the manufacturer.
  4. Never share your makeup with friends or family members.
  5. Avoid liners or shadows with glitter, as the particles can easily disrupt your tear film.
  6. Try to stick to cream-based products for the least amount of irritation.
  7. Apply eye makeup to the outside of your eyelashes. Lining the inner rim of your eyelids can clog or irritate the meibomian glands.
  8. Be diligent about eye hygiene. Always thoroughly wash your face and eyes before bed with eye-safe cleaning products.
  9. Visit your dry eye optometrist!

Frequently Asked Questions with Dr. Nathalie Cassis

Q: Are there any vitamins I can take to prevent or relieve dry eye disease?

  • A: Yes, certain foods help the eyes stay properly hydrated. Specific vitamins, fatty acids and trace elements are good not only for our overall health but also for our tear film. These include Omega 3 fatty acids, Vitamins A, B, C, E, as well as Lutein and Zeaxanthin.

Q: Is dry eye syndrome dangerous for eye health?

  • A: When chronic dry eye isn’t treated, several eye conditions can occur: pink eye (conjunctivitis), keratitis (corneal inflammation) and corneal ulcers. DES can also make it difficult or impossible to wear contact lenses, cause difficulty with reading and trigger headaches.

6 Reasons Scleral Lenses Can Manage Your Dry Eye Syndrome

6 Reasons Scleral Lenses Can Manage Your Dry Eye Syndrome 640×350If your eyes are chronically itchy, dry, red or irritated, there’s a good chance you have dry eye syndrome.

Eye drops and artificial tears may provide temporary relief, but they often don’t help individuals with chronic or severe dry eye syndrome. That’s why so many people seek out other treatment options.

One such option is scleral lenses. Although custom-made scleral contact lenses are widely used to correct corneal abnormalities and refractive errors, they can also help patients with intractable dry eye symptoms. Here’s why:

1. Scleral lenses don’t irritate the cornea

Standard contact lenses are typically not an option for people who need vision correction and also have persistent dry eye syndrome. Standard soft lenses sit on the cornea, which can be exceedingly irritating. In contrast, scleral lenses vault over the cornea and sit on the sclera (the white of the eye). The lenses do not come into contact with the corneal surface, reducing discomfort.

2. The scleral lens design ensures constant hydration of the eye

Thanks to sclerals’ unique design, saline solution fills the space between the surface of the cornea and the scleral lens. This provides the eyes with constant hydration. To help lubricate and promote healing of the ocular surface, artificial tears and antibiotics can be administered to the lens’ bowl prior to insertion.

3. Scleral lenses protect the cornea

Dry eye syndrome makes the corneas more susceptible to injury. Due to the mechanical friction of the eyelids on the cornea, even something as basic as rubbing the eye or even blinking can exacerbate any current corneal damage. Sclerals can act as a barrier between a patient’s eyes and their eyelids, as well as the outside environment.

4. Sclerals allow the eye to regain a healthier appearance

Dry eye patients frequently present with eyes that are red or bloodshot. Scleral lenses perform a therapeutic role by providing a shield from the outside world and ensuring a constant supply of hydration. The redness will begin to dissipate once the eyes receive enough moisture.

5. Patients can continue using artificial tears and eye drops while wearing scleral lenses

Patients can continue to moisten their eyes with preservative-free eye drops or artificial tears while wearing scleral lenses. With that said, many patients discover that after they start wearing scleral lenses, they can reduce the frequency of artificial tear use. Some need eye drops only at night, after they have removed their lenses.

6. Scleral lenses can dramatically improve quality of life

Patients with dry eye syndrome can feel worn down by the almost constant discomfort and eye fatigue, not to mention looking tired all the time due to eye redness.

For patients who have suffered from severe dry eye syndrome for months or years, finding relief while enjoying clear and comfortable vision definitely boosts their quality of life.

If you suffer from dry eye syndrome and have been looking for a more effective treatment option, ask Dr. Nathalie Cassis about scleral lenses. Call Scleral Lens and Keratoconus Center at Envision Ghent Optometry today to schedule your consultation and learn more about these special lenses.

Scleral Lens and Keratoconus Center at Envision Ghent Optometry serves patients from Norfolk, Virginia Beach, Chesapeake, and Suffolk, Virginia and surrounding communities.

Frequently Asked Questions with Dr. Nathalie Cassis

Q: What are scleral lenses?

  • A: Scleral contact lenses are gas-permeable lenses that sit on the sclera (the white area of the eye) and form a dome over the cornea. This dome forms a new optical surface over the injured, uneven or dry cornea, allowing for sharper and more comfortable vision.

Q: How long do scleral lenses last?

  • A: These rigid gas permeable contacts are made of high-quality, long-lasting materials and typically last 1-3 years. While scleral lenses are more expensive than standard contact lenses, they’re a worthwhile investment, particularly for those with hard-to-fit eyes, keratoconus, astigmatism or dry eye syndrome.

5 Common Keratoconus Questions, Answered

5 Common Keratoconus Questions, Answered 640If you’re reading this, you or someone you care about may have been recently diagnosed with keratoconus. We’ve compiled a few commonly asked questions about keratoconus to help you understand what it is, what causes it, and how your eye doctor can help.

1. What Is Keratoconus?

Keratoconus is a progressive, non-inflammatory disease that causes the cornea to thin and bulge, resulting in a cone-shaped cornea. Over time, this bulge leads to myopia and irregular astigmatism, and vision becomes progressively distorted. Ongoing treatment is crucial to prevent significant vision loss.

2. What Are the Symptoms of Keratoconus?

Many patients aren’t aware that they have keratoconus, which typically begins during the teenage years.

Symptoms of keratoconus include:

  • Difficulty seeing at night
  • Blurry vision
  • Halos and glare around lights
  • Increased sensitivity to bright light
  • Headaches or eye irritation associated with eye pain
  • Progressively worsening vision that’s not easily corrected

3. What Causes Keratoconus?

While there is no one cause of keratoconus, a paper published in Biomed Research International (2015) identified these risk factors:

  • Genetics. About one in 10 people with keratoconus also has a family member with the condition.
  • Inflammation. Irritation and inflammation from allergies, asthma and other atopic eye diseases can lend to the development of keratoconus.
  • Frequent eye rubbing. Intense and frequent eye rubbing is thought to thin out the cornea and can worsen the condition.
  • Underlying disorders. Keratoconus has been associated with several conditions, including Down syndrome, Ehlers-Danlos syndrome, Leber congenital amaurosis, Marfan syndrome and Osteogenesis imperfecta.
  • UV light. UV light can cause oxidative stress, which weakens the corneas in predisposed eyes.
  • Weak collagen. In a healthy eye, small protein fibers called collagen help keep the cornea in a dome-like shape and free from bulges. In the case of keratoconus, the collagen fibers become weak and therefore can’t maintain the shape of the eye, which causes the cornea to bulge.

4. How Is Keratoconus Treated?

Scleral lenses are the most common and successful treatment for patients with keratoconus. These are specialized rigid, gas permeable contact lenses that have a very wide [diameter] and vault over the entire corneal surface, making them effective and comfortable for people with keratoconus.

5. Is There a Cure for Keratoconus?

Currently, there is no cure for keratoconus. However, in most cases, it can be successfully managed.

For mild to moderate keratoconus, scleral contact lenses are typically the treatment of choice, as they provide clear, comfortable vision.

A relatively non-invasive procedure called corneal cross-linking (CXL) can stabilize and strengthen a thinning and irregularly shaped cornea.

At Scleral Lens and Keratoconus Center at Envision Ghent Optometry, we can recommend the best treatment options for your keratoconus, to help preserve your vision, and ensure the highest level of comfort and visual acuity. Call to schedule an appointment to start discussing your keratoconus treatment options.

Scleral Lens and Keratoconus Center at Envision Ghent Optometry serves patients from Norfolk, Virginia Beach, Chesapeake, and Suffolk, all throughout Virginia.

Frequently Asked Questions with Dr. Nathalie Cassis

Q: Can You Go Blind If You Have Keratoconus?

  • A: Keratoconus does not typically cause total blindness. However, as keratoconus progresses it can cause visual impairment including blurred distance vision, distortion, glare, astigmatism, extreme light sensitivity and even vision loss that can be classified as “legal blindness.

Q: Does keratoconus affect both eyes?

  • A: Yes, in approximately 90% of keratoconus cases, the disease will manifest in both eyes. However, the rate of progression and the timing of the onset of the disease is different for each eye.

Why is My Dry Eye More Severe in the Mornings?

sleepy mornings 640Waking up in the morning is hard enough, but waking up with stinging, burning eyes is even worse! If your eyes feel itchy and scratchy, this miserable morning sensation may be caused by dry eye syndrome. Your tear glands may be clogged or producing insufficient tears and oils to retain moisture.

But why do certain people experience more acute dry eye symptoms in the mornings? Here are some reasons:

What Causes Red, Itchy or Painful Eyes Upon Waking?

Nocturnal Lagophthalmos

Nocturnal lagophthalmos is the inability to close one’s eyelids completely during sleep. Since the surface of your eye is exposed at night, it becomes dry. Left untreated, this condition can damage your cornea.

Blepharitis

Blepharitis is an inflammatory condition of the eyes caused by bacterial overgrowth. These bacteria are active at night, causing dry eye-related symptoms of redness, soreness and irritation upon waking.

Environment

A gritty sensation in your eyes can also be caused by the environment. For example, sleeping directly in front of or under an air vent, heating units, or ceiling fans can dry out your eyes. In addition, sensitivity to allergens like dust that accumulate in the bedroom can cause your eyes to become dry and irritated.

Medications

Some types of over-the-counter and prescription medication can dehydrate the eyes. These include:

  • Antihistamines and decongestants
  • Antipsychotic medications
  • Antidepressants
  • Hypertension drugs
  • Hormones
  • Drugs for gastrointestinal problems
  • Pain relievers
  • Skin medications
  • Chemotherapy medications

In the majority of cases, medication-related dry eye symptoms will resolve once you discontinue the meds. However, it may take several weeks or months for symptoms to completely disappear.

Age

Many people develop dry eye symptoms with age, as tear production tends to decrease and becomes less efficient as we grow older.

How to Treat Morning Dry Eye

Depending on the cause, morning dry eye can be treated with sleeping masks, lubricating eye drops and ointment applied right before bed. To ensure that you sleep in a moisture-rich environment, consider using a humidifier. In severe cases of nocturnal lagophthalmos, eyelid surgery may be necessary.

If you are tired of waking up to red, burning eyes, visit your eye doctor for long-lasting relief. Contact Dry Eye Center at Envision Ghent Optometry to determine the cause of your morning dry eye and receive an effective treatment plan.

Frequently Asked Questions with Dr. Nathalie Cassis

Q: What causes dry eye?

  • A: Dry eye can occur if the glands in your eyelids don’t produce enough oil to keep your tears from evaporating, or if you don’t produce enough water for healthy tears. No matter the cause, it’s important to have your condition diagnosed and treated to protect your vision and ensure good eye health.

Q: Can dry eye be cured?

  • A: Dry eye is a chronic condition, so there’s is no cure for it. However, many treatment methods can help you manage this condition for long-term relief. If you have dry eye syndrome, we invite you to contact us to discover the best treatment for your needs.

4 Reasons Why Scleral Lenses Are a Big Deal

happy girl wearing contact lenses 640Scleral contact lenses have been called “life-changing” and “transformative” by patients who wear them.

What makes these contact lenses so revolutionary?

What Are Scleral Lenses?

Scleral lenses are contacts that vault over the entire cornea and rest on the white part of the eye (sclera). Their diameter is much larger than standard lenses, which adds to their comfort and compatibility with hard-to-fit eyes.

Here’s why they’re gaining popularity in the contact lens world and why patients and doctors are calling sclerals a big deal.

1. Sclerals are Ideal for People with Corneal Irregularities or Dry Eyes

There was a time when patients with corneal irregularities or severe dry eye syndrome weren’t able to wear contact lenses at all, due to the discomfort associated with direct corneal contact. Nowadays, patients with keratoconus, other corneal aberrations or dry eye can successfully wear scleral contact lenses and enjoy comfortable and crisp vision.

Scleral lenses are also great for patients with corneal dystrophy, high astigmatism, Sjorgren’s syndrome, corneal trauma and corneal ectasia, or who have undergone cataract surgery.

2. They’re Completely Custom-Made

Each pair of scleral contact lenses is custom-designed to gently and securely rest on your unique eyes. The fitting process for scleral lenses starts with corneal topography, where the optometrist creates a digital map of your eye’s surface. This information is then used to customize your perfectly fitted pair of sclerals.

3. They Offer Optimal Visual Clarity and Comfort

The liquid reservoir that sits between the lens and the eye helps enhance the visual optics of the lens. Moreover, scleral lenses are made of very high-grade materials and don’t place any pressure on the cornea, delivering ultimate all-day comfort. Many patients have reported that they comfortably wear sclerals for up to 14 hours a day, which is longer than the wear time for standard soft contact lenses.

4. They Promote Eye Healing

Scleral contact lenses protect the eye by surrounding it with an oxygen-permeable, liquid-filled chamber. This hydrating environment gives the eye the moisture and oxygen it needs to stay healthy and ward off outside irritants.

This can also explain why scleral lenses promote healing of the eye’s surface, whether after a corneal transplant or when recovering from a chemical burn or other eye injury.

If you or a loved one have been diagnosed with a corneal condition that prevents you from wearing standard lenses, consider scleral lenses. To schedule an appointment or to learn more, call Scleral Lens and Keratoconus Center at Envision Ghent Optometry in Norfolk today!

Scleral Lens and Keratoconus Center at Envision Ghent Optometry serves patients from Norfolk, Virginia Beach, Chesapeake, Suffolk and throughout Virginia.

Frequently Asked Questions with Dr. Nathalie Cassis

Q: #1: How long do a pair of scleral lenses last?

  • A: Scleral lenses can last 1-2 years before requiring replacement. Your optometrist will provide you with instructions on how to wear and care for your lenses to keep them feeling fresh and clean, day in day out.

Q: #2: Are scleral lenses expensive?

  • A: Just like any other customized product, scleral lenses tend to be more expensive than standard soft contact lenses. Although they have a higher price point, most patients who wear them will tell you that their comfort, visual clarity and stability make them worth the cost.

Can Drinking Coffee Relieve Dry Eyes?

Can Drinking Coffee Relieve Dry Eyes 640Many of us enjoy a cup or two of coffee in the morning to keep our eyes awake and mind alert. But what else can caffeine do for our eyes?

If you suffer from dry eye syndrome (DES), characterized by dry, itchy and red eyes, you may have been advised by a friend or doctor to steer clear of caffeinated coffee due to its diuretic effect. Caffeinated beverages increase the frequency of urination, which leads to water loss. Yet some research suggests that a cup of caffeinated joe might actually promote tear production.

Below, we’ll explore scientific research that studies the relationship between caffeine consumption and tear film.

What is Dry Eye Syndrome?

  • Dry eye syndrome (DES) is an eye condition characterized by dry, stinging, red, itchy eyes. It can be caused by several factors: poor tear quality, insufficient tears, allergies, environmental irritants and excessive digital screen time. Left untreated, DES can lead to corneal damage and scarring and even permanent vision loss in severe cases.
    Certain foods and beverages have been shown to improve the symptoms of DES, like fish high in omega 3s, leafy greens, seeds, nuts, and…possibly coffee.

How Does Caffeine Consumption Impact Dry Eye Syndrome?

  • Caffeine contains a chemical called xanthine, which has been shown to stimulate tear production when applied topically to the eye. As yet, there is insufficient published research to confirm that ingesting xanthine provides the same tear-producing effect, though preliminary studies seem to suggest that it does.

 

A study published in Optometry and Vision Science found that drinking caffeinated beverages significantly increased tear production after 45-90 minutes. Interestingly, age, gender and body mass had no bearing on the outcome.

Another study, published in Ophthalmology, found similar results. Researchers measured the participants’ tear film twice: once after consuming caffeine and once after drinking a placebo. Their tear film was thickest after consuming caffeine, especially in those with a specific genetic makeup.

While both of these studies showed promising results, they didn’t include enough participants to accurately project the findings onto the general population.

If You Have Dry Eye Syndrome, We Can Help

Finding relief from dry eye syndrome relies on understanding the root cause of your symptoms. Only your eye doctor can diagnose the problem and determine the best treatment for you, whether in the form of medicated or lubricating eye drops, in-clinic treatments, personalized eye hygiene products like eyelid cleansing wipes, nutritional supplements and more.

For long-lasting relief from dry eye syndrome, schedule your dry eye consultation with Dry Eye Center at Envision Ghent Optometry today.

Living With Keratoconus | Kenneth’s Story

Kenneth’s Story 640From the time Kenneth was 11 years old, he wore glasses to correct his quickly deteriorating vision. He was always forced to sit at the front of the classroom and felt embarrassed by it. This time in his life marked the beginning of seemingly endless visits to various eye doctors to try and figure out what was causing his vision problems.

Four years later, at the age of 15, Kenneth was diagnosed with keratoconus, a progressive eye disease that affects the shape and condition of the cornea. Kenneth was referred by his ophthalmologist to an optometrist who [specializess] in treating keratoconus.

The optometrist explained that keratoconus is a condition that causes the cornea to thin and bulge out in a cone-like shape, leading to visual impairment. The early stages of this progressive eye disease usually cause mild to moderate vision problems that can be corrected with eyeglasses. But as the cornea’s shape continues to distort, glasses are no longer suitable and rigid contact lenses must be prescribed.

The optometrist prescribed rigid gas permeable contact lenses, which significantly improved Kenneth’s vision. But Kenneth sometimes found his contacts hard to manage, and even uncomfortable at times. People would tell him to just ‘switch back to glasses’ and ‘stop wearing the lenses if they give you so much grief.’

That wasn’t possible. He simply couldn’t see without the contacts.

Thankfully, before Kenneth’s condition progressed to the point where cornea surgery was required, new technology gave him fresh hope.

At the age of 20, Kenneth was fitted for scleral contact lenses for the first time. The day of the fitting was an emotional one for him and his family, as he was truly able to see the world around him in detail—and with great comfort.

Kenneth walked out of the optometrist’s practice, looked around, and saw leaves on the trees for the first time in 5 years. Prior to this, his perception of trees were brown stumps with green shrubbery—but never leaves.

He noticed that the cars driving past him on the street looked astonishingly clean. Nothing seemed faded anymore. Colors were vivid, lines were sharp.

The detail and clarity of each object were genuinely overwhelming for him. His mom, who also suffers from keratoconus, was overcome with emotion as she watched her son visually experience his surroundings in a whole new way.

From that day forward, Kenneth’s life changed drastically. His scleral contact lenses enabled him to function normally and achieve his goals. Wearing his sclerals allows him to work, exercise, socialize and be his authentic self.

Kenneth confesses that when he doesn’t wear his sclerals, his entire personality changes. He becomes timid, quiet and apprehensive.

Having keratoconus will no longer hinder Kenneth from living his best life, and it doesn’t have to hinder you or an affected loved one.

To a person with corneal disease, scleral lenses can be truly life-changing. If you or a loved one has keratoconus or other corneal irregularities, contact Scleral Lens and Keratoconus Center at Envision Ghent Optometry today.

Q&A

Q: #1: How do scleral lenses work?

  • A: Scleral contact lenses are hard lenses that have a much larger diameter than standard soft contact lenses. They vault over the entire cornea and rest on the sclera (the white of the eye) so that no part of the lens is touching the cornea itself. The lens holds a reservoir of soothing and nourishing fluid between the eye and the lens, providing the best in visual clarity and comfort.

Q: #2: What other conditions do scleral lenses help with?

  • A: Any patient with irregular corneas can benefit from scleral lenses. They’re also suitable for patients with severe dry eye syndrome, as the fluid reservoir helps maintain comfort and ocular hydration. They’re also great for patients with very high refractive errors (high myopia, hyperopia, or astigmatism). Speak to your eye doctor if you think scleral lenses may be right for you.

Why Computer Use Can Cause Dry Eye & Eye Strain

Long Term Computer Use 640Nearly 60% of the Western world use some kind of digital device — a phone, computer, tablet, TV — for at least 5 hours a day. All that screen time can result in eye irritation and dryness. In fact, dry eyes and eye strain have become so common that researchers have coined a name for it: computer vision syndrome (CVS).

What is Computer Vision Syndrome?

Computer vision syndrome (CVS) is an eye condition commonly experienced after staring at a computer screen, at arm’s length or closer, for an extended period of time. It is characterized by eye strain and dry eyes.

Because more people work and study at home as a consequence of the COVID-19 pandemic, eye doctors are reporting a significant rise in the number of adults and children exhibiting these symptoms.

The symptoms of CVS include:

  • Red, watery eyes
  • Burning or stinging eyes
  • Sensitivity to light
  • Blurred vision
  • The feeling of having something in your eyes

Computer vision syndrome symptoms are similar to those found among dry eye syndrome sufferers, a condition that also tends to develop as a result of extended computer use when blinking is reduced. Blinking is critical for good eye health as it rejuvenates the tear film on your eyes, ensuring constant hydration and protecting them from damage.

5 Tips to Prevent CVS

Luckily, computer vision syndrome can be effectively managed with a few simple adjustments to your screen time.

  1. Take regular breaks. Follow the 20-20-20 rule to prevent staring at your screen for too long. Take a break from your computer or device for 20 seconds, every 20 minutes, and look at something at least 20 feet away.
  2. Adjust your angle. Make sure your screen is 20-28 inches from your eyes and that the center of the screen is 4-5 inches lower than eye level.
  3. Use a cool-air humidifier. A humidifier adds moisture to the air and prevents your eyes from drying out.
  4. Reduce glare. Your eyes work harder to read when there is glare reflecting off your screen. Make sure your screen is positioned in a way that prevents glare from windows and lighting. You can also add a glare filter for eye comfort.
  5. Get computer glasses. Computer glasses allow your eyes to focus on a computer screen with less effort and the blue-light filter may also reduce exposure to potentially harmful blue light emitted by digital devices.

By taking regular breaks from your screen, you give your eyes and body a much-needed rest. To learn more about computer vision syndrome and to receive treatment to alleviate dry eye symptoms and eye strain, contact Dry Eye Center at Envision Ghent Optometry.

 

Frequently Asked Questions with Dr. Nathalie Cassis

 

Q: What’s the link between staring at a computer screen and dry eye?

  • A: Staring at a computer screen can reduce the number of times a person blinks by 30%. That’s problematic because blinking is essential for lubricating the eyes and keeping the protective tear film that covers the eye intact. If you find your eyes becoming irritated or uncomfortable at work, try to blink more, especially while using the computer and reading.

Q: Can blue light glasses help avoid computer vision syndrome and dry eye?

  • A: Spending long periods of time on a computer or device can negatively affect your eyes, potentially leading to computer vision syndrome and dry eye. Symptoms include blurred or double vision, headaches, eye strain, eye fatigue, sleep disruptions, and dry eyes. Computer glasses offer blue light protection by reducing the dangerous effects of blue light and the risks of computer vision syndrome.
