Millions of Americans suffer from dry eye syndrome. Symptoms are often described as a feeling of dryness, burning and gritty sensation or itchiness.  Eye strain, sensitivity to light and blurred vision can also be associated with dry eye.  It may not sound logical that dry eye would cause excess tearing but it’s the eyes response to discomfort.  If lack of tears makes the eye dry, it prompts the gland that makes tears to release a large volume of them, overwhelming the tear drainage system.  Sometimes, people do not produce enough tears or the right quality of tears to keep their eyes comfortable and healthy. When you blink, a film of tears spreads over the eye, which makes the surface of the eye clear and smooth.   The tear film consists of three layers- oily, watery and mucus. Each layer has its own purpose.  The oily layer forms the outermost surface of the tear film.  Its main purpose is to smooth the tear surface and reduce evaporation of tears. The middle watery layer makes up most of what we ordinarily think of as tears.  This layer cleanses the eye and washes away particles or irritants. The inner layer consists of mucus that allows the watery layer to spread evenly over the surface of the eye to help it remain moist. Without tears, the mucus does not stick to the eye. Treatments for dry eyes may include artificial tear drops or ointments, temporary or permanent plugs.  You should see your eye doctor for a complete eye exam to determine what will work best for you.
