Dry Eyes Symptoms
As the name suggests, dry eyesare a result of decreased tear production in the eye or increased evaporation of the tear film. The function of a tear film is to help the eye maintain a normal, optimal vision.Dry eyescan also result due to an abnormal production of mucus or lipids secreted by one of the three tear layers. Decreased production of tears is usually seen with age, hormonal changes or several autoimmune diseases like rheumatoid arthritis. Even medications like antihistamines, anti-depressants or oral contraceptives may lead to dry eyes. Moreover, at times due to decreased blinking of eyes or difficulty in closing them, tears tend to evaporate, resulting in dry eyes. So, while reading, watching television or performing any task which requires optimum attention, it is often seen that one suffers from dry eyes. In the medical dictionary, dry eyesare known as "keratoconjunctivitis sicca", a Latin term which means "dryness of the cornea and conjunctiva". It affects a significant portion of the population, especially those who have reached the age of 40. Besides making your eyes feel scratchy and gritty, dry eyes have several other symptoms.
