A Common Cause of Eye Irritation

Stinging, irritated eyes, and blurred vision may indicate nothing more than a case of blepharitis — an unpleasant but, in most cases, relatively harmless condition. Blepharitis is a chronic eyelid inflammation caused by a variety of irritants and/or the inability to maintain proper eye lubrication. In some cases, bacterial infection may be involved. If you suffer from this annoying problem, don’t feel obliged to live with it — see your eye care professional to discover the cause of your blepharitis and get advice on how to relieve yourself of it.

Blepharitis may take one of two forms, anterior (toward the front of the eyelid, where the eyelashes begin) and posterior (on the inner edge of the lid). You may even have both types of blepharitis at the same time. Anterior blepharitis often occurs when dandruff flakes, allergens, or bacteria irritate the eyelid and eyelashes. Posterior blepharitis is the result of a failure on the part of tiny glands within the eyelid, known as meibomian glands, to produce sufficient lubrication between the eyelid and the cornea of the eye.

Typical symptoms of blepharitis include the formation of crusts along the eyelids, eye pain, redness, oozing, abnormal tear formation, irregularities in the arrangement of your eyelashes, and a tendency for the eyelids to stick together.
