Do your eyes itch or burn when wearing contact lenses? There are several reasons why you may be experiencing contact lens discomfort. Discover the possible causes behind the problem and see what you can do to relieve your discomfort.
What Causes Contact Lens Discomfort?
Some of the top causes of uncomfortable contacts are:
Dry eye syndrome is a common condition that arises when your tears can’t keep your eyes sufficiently lubricated due to an imbalance in the tear film. Certain diseases, medications and environmental factors, like high levels of dryness and wind, can cause or contribute to red, itchy or irritated eyes, especially when wearing contacts.
Allergens are typically harmless substances that induce an allergic response in certain people. Pollen, mold, dust and pet dander are some of the most common airborne allergens that trigger eye allergies. Cosmetics and certain eye drops, such as artificial tears with preservatives, can also induce eye allergies, which can make contact lens wear uncomfortable.
The cornea at the front of the eye may be irregularly shaped due to astigmatism, keratoconus, eye surgeries (i.e. LASIK or cataract surgery), eye injuries or burns, scarring, corneal ulcers and/or severe dry eye. Irregular corneas often prevent traditional contact lenses from fitting correctly and comfortably.
Symptoms of Contact Lens Discomfort
- Burning, itchy, stinging eyes
- Sensation of something being stuck is in the eye
- Excessive watering or tearing of the eyes
- Unusual eye secretions
- Redness of the eyes
- Reduced sharpness of vision
- Blurred vision, rainbows, or halos around objects
- Sensitivity to light
How to Relieve Contact Lens Discomfort
Try Different Contact Lenses
Nowadays, there are many types of contact lenses on the market, including specialty contacts for dry eyes and astigmatism. Meet with our optometrist for a personalized eye exam for contacts.
With the variety of contact lens brands available, switching to a different contact lens may be the simplest answer if you’re experiencing discomfort that isn’t connected to improper fitting or issues with tear production. If your existing lenses fit well but still irritate and dry out your eyes, speak to us about trying a different design or brand of contact lenses, or changing your lens-wearing schedule.
Artificial Tears or Eye Drops
Over-the-counter artificial tears or eye drops are a common way to temporarily relieve contact lens discomfort. However, it’s important to keep in mind that unless prescribed by an eye doctor, they may not be treating the root of the problem.
Moreover, certain eye drops are incompatible with contact lenses, and may damage your contacts or harm your eyes. We also recommend staying away from products that claim to remove redness from your eyes, which temporarily reduce the size of blood vessels to lessen redness, but do not address the underlying cause of the condition, and can actually worsen it over time.
Take Good Care of Your Lenses
Inadequate contact lens care leaves residue on your lenses, which can discomfort, harmful eye infections and inflammation. Below are a few important contact lens hygiene guidelines to follow:
- Before handling your contact lenses, thoroughly wash and dry your hands.
- Remove your lenses before showering, bathing or swimming to prevent infection.
- Do not sleep in your contact lenses (unless they are approved for sleeping).
- Replace your contact lenses according to the manufacturer’s instructions (e.g., don’t reuse daily wear lenses).
- Regularly clean your contact lens case and ask your eye doctor when to replace it.
- Only use a contact lens solution that is appropriate for your lenses.
- Never reuse or mix contact lens solutions.
- Schedule regular appointments with your eye doctor.

What kinds of contacts are available?
Contact lenses are available in a wide range of materials and replacement schedules. Disposable contact lenses and extended wear contacts are the most convenient for many users.
I’ve already been fitted for contact lenses, so why did my optometrist ask me to come back?
If you’re asked to return a week later, it’s because your optometrist wants to rule out any issues, such as contact lens-related dry eye or irritation.
If it’s been around a year since your last eye checkup, you’ve likely been contacted to check whether your prescription has changed and to evaluate your eye health. The sooner problems are detected and treated, the better the outcome.
Did you know that some eye conditions are associated with sleep apnea? According to the National Sleep Foundation, more than 18 million Americans have sleep apnea, and Health Canada reports similar prevalence. It’s a sleep disorder where people stop breathing — often multiple times per night — while sleeping.
If you have sleep apnea: it tends to take longer for your tears to be replenished, you’re more likely to have ocular irritation, you have a higher chance of developing floppy eyelids, and you’re at increased risk for glaucoma.
What Is Obstructive Sleep Apnea?
There are different types of sleep apnea. The most common one is obstructive sleep apnea (OSA). During OSA, your airway becomes partially blocked due to relaxed muscles in your nose and throat. This causes apnea (the absence of breathing) or hypopnea (abnormally shallow, slow breathing). It’s twice as common in men, and is more likely to affect people with obesity, hypertension, diabetes or heart disease.
What are the common symptoms of sleep apnea?
Sleep apnea occurs when the muscles in the back of your throat relax too much to allow normal breathing. These temporary breathing lapses cause lower-quality sleep and affect the body’s oxygen supply, which can lead to potentially serious health consequences.
While snoring is a common symptom, not everyone who snores has sleep apnea. Interrupted sleep can cause excessive daytime sleepiness, fatigue, irritability or depression, headaches in the morning, difficulty concentrating and thinking, and a sore throat.
Which Eye Conditions Are Associated With Sleep Apnea?
Glaucoma occurs when increased pressure within the eye damages the optic nerve, which connects the eye to the brain, leading to vision loss and sometimes blindness. In some cases, it might be due to a drop in blood oxygen levels, which happens when you stop breathing. However, CPAP machines, one of the most common treatments for sleep apnea, can also cause glaucoma.
So, people with sleep apnea — even if it’s being treated — need to get their eyes checked on a regular basis for glaucoma.
Floppy Eyelid Syndrome
Floppy Eyelid Syndrome (FES) is an eye condition where a person has an unusually large and floppy upper eyelid. It can cause eye redness, irritation, discharge, or blurry vision — and over 90% of people with FES also have sleep apnea.
Non-Arteritic Anterior Ischemic Optic Neuropathy
Non-arteritic anterior ischemic optic neuropathy (NAION) is an eye condition that occurs when there is a loss of blood flow to the optic nerve. Patients typically complain of significant vision loss in one eye without any major pain. Approximately 70-80% of patients with NAION have been found to have OSA.
Retinal Vein Occlusion
Also referred to as an ‘eye stroke,’ retinal vein occlusion (RVO) is a blockage of the small veins that carry blood away from the retina. A recent study of 114 RVO patients found that sleep apnea was suspected in 74% of the patients that had previously been diagnosed with RVO.
Other Eye Health Issues Associated With Sleep Apnea
Some other ocular conditions that are more common in patients with sleep apnea include: papilledema, keratoconus, and central serous chorioretinopathy. Furthermore, in addition to glaucoma mentioned above, CPAP machines are associated with dry eye syndrome and bacterial conjunctivitis.
Talk To Your Doc
Get eye exams regularly to rule out eye disorders and prevent potential vision loss, especially if you have been diagnosed with sleep apnea. At Harrel Eyecare in Tulsa we encourage you to share your medical history with us so we can better diagnose and treat any eye conditions or ocular diseases you may have, and help you keep your eyes nice and healthy.
If you don’t see well while driving at night, there’s a chance you have night blindness. Night blindness, or nyctalopia, is the inability to see well at night or in dim lighting. It’s not considered an eye disease, but rather a symptom of an underlying problem.
Our eye doctor can help diagnose, manage and treat your night blindness so that you can enjoy being out at night again.
Here are 4 things you should know about night blindness:
Causes of Night Blindness
The inability to see well at night can be the result of a condition such as:
Vitamin A Deficiency — Vitamin A helps keep your cornea, the layer at the front of your eye, clear; it’s also an important component of rhodopsin, a protein that enables you to see in low light conditions. Although uncommon in North America, deficiency of this vitamin can induce night blindness.
Cataracts — A buildup of protein clouds the eye’s lens, leading to impaired vision, especially at night and in poor lighting conditions.
Diabetic Retinopathy — Damage to the eyes’ blood vessels and nerves can result in vision loss, including difficulty seeing at night.
Glaucoma — This group of eye diseases is associated with pressure build-up in the eye that damages the optic nerve. Both glaucoma and the medications used to treat it can cause night blindness.
Myopia — Also called nearsightedness, myopia makes distant objects appear blurry, and patients with it describe a starburst effect around lights at night.
Keratoconus — An irregularly shaped cornea causes blurred vision and may involve sensitivity to light and glare which tend to be worse at night.
Retinitis Pigmentosa (RP) — A progressive genetic eye disease which can be associated with other diseases, RP leads to night blindness and peripheral vision loss.
Usher Syndrome — This genetic condition causes both hearing loss and vision loss, including night blindness and RP, mentioned above.
Symptoms of Nyctalopia
Since night blindness is a symptom of some serious vision problems, it’s important to get your eyes checked regularly to ensure that everything is in good working order. Contact your eye doctor as soon as possible if you notice that you don’t see as well in dim light as you used to, such as when driving at night or when adjusting from being outdoors in the sunshine to being indoors.
Symptoms of Night Blindness Include:
- Reduced contrast sensitivity
- Difficulty seeing people outdoors at night
- Difficulty seeing in places with dim lighting, like a movie theater
- Trouble adapting to the dark while driving
- Excessive squinting at night
- Trouble adjusting from bright areas to darker ones
Treatments for Night Blindness
Your eye doctor will want to diagnose the cause of your night blindness in order to treat it. For example, in the rare case of vitamin A deficiency, it can be treated with vitamin supplements and vitamin-A rich foods; myopia can be corrected with eyeglasses or contact lenses. Other conditions may require medications or surgery.
If night blindness is caused by a birth defect, Usher syndrome, or retinitis pigmentosa, low vision aids and devices can help you make the most of your remaining vision.
While there is no proven way to prevent night blindness resulting from genetic conditions or birth defects, consuming healthy, nourishing foods and taking certain vitamin supplements may prevent or slow the onset of some eye conditions that cause night blindness.
