Do your contact lenses spend more time in their case than in your eyes? Itching and redness, common complaints among contact lens wearers, can make it difficult to wear the lenses for more than an hour or two. The uncomfortable symptoms often occur as a result of allergies, but may develop due to other reasons. Identifying the source of your itch is the key to finding relief.
Allergies are a common cause of itchy eyes. In fact, it's estimated that almost half of the world's population is affected by some sort of allergy every year, according to the American Academy of Allergy Asthma and Immunology. If your itchy eyes are accompanied by sneezing and congestion, allergies may be to blame.
When you're exposed to allergens, such as pollen, grasses or pet dander, your body immediately switches to defensive mode in an attempt to get rid of the foreign substance. Although these allergens aren't dangerous, your body doesn't see it that way. It produces histamines, chemicals that trigger allergic responses designed to eliminate allergens as soon as possible. As histamines flood your body, your eyes water and itch. Your symptoms can be worse when you wear your contacts, as the lenses may trap allergens.
Allergies to contact lens cleaning solutions and the lenses themselves may also cause itching. Keep in mind that allergies can develop at any point in your life. Just because you've never had allergies in the past doesn't mean that they aren't the cause of your itchy eyes.
Sometimes itching occurs after you come in direct contact with an allergen or irritant. For example, makeup and other products you wear on your face can cause contact dermatitis. If you suffer from this condition, you'll develop an itchy rash where your skin touched the allergen or irritant.
Dry eyes are another common cause of itching. Other symptoms of dry eye include tearing, burning or the feeling that something is stuck in your eye, even though it looks perfectly fine.
Blepharitis, or eyelid inflammation, often accompanies dry eye, but can also occur on its own. If you have blepharitis, you may notice crusty deposits or dandruff-like flakes on your eyelids, in addition to itchy eyelids, watery eyes, burning, stinging and a foreign body sensation.
Contact Lens-Induced Conjunctivitis
Contact lens-induced conjunctivitis, also called giant papillary conjunctivitis, causes small bumps to form on the inner surface of your eyelids. The bumps develop when contact lenses or allergens irritate the lining of eyelids. Failing to clean your lenses often enough can cause the condition, but it may also occur if protein deposits build up on the lenses. Contact lens-induced conjunctivitis causes itching, redness, blurred vision and foreign body sensation. You may also notice an accumulation of string-like strands of mucus.
