Your eyes are full of tears when you cry. When you are happy, your eyes are still full of tears. In fact, tears are important to maintain the health of your eyes. Tears are a mixture of water, oil, mucus, and antibodies. Water keeps your eyes moist. Oils help in lubrication. Mucus is responsible for a proper distribution of the moisture and lubrication. . . .+
Dry eye is a common eye problem that occurs when your eyes do not produce enough quality tears or when the tears evaporate too quickly. The tears produced are inadequate and/or of poor quality. Dry eyes feel quite uncomfortable and can make it difficult to perform certain activities such as watching a TV or using a computer for extended time periods.
Dry eyes symptoms generally affect both the eyes. The symptoms tend to come and go. This is a chronic eye condition and usually gets worse over time. You may experience pain, stingy or burning sensation in eyes, and redness. Your eyes become tired when you are at computer or reading for a prolonged time.
Your doctor will first do an eye examination. Generally, the eye exam provides enough inputs to confirm whether you have dry eyes. If the test results are uncertain, your doctor will order some other tests. Schirmer's test is a common test for diagnosis of dry eyes that identifies volume of tears produced.
No permanent cure exists for dry eye syndrome. Many medical treatments are available that aim to easy the symptoms and feel you comfortable. The treatment your doctor chooses depends on the severity of the condition. Most cases can be managed with the use of lubricants that serve as artificial tears.
Eye drops are generally the preferred method of treating dry eyes. Many prescription and over-the-counter eye drops are available that a doctor may choose from and recommend for you based on your condition. These eye drops are often called artificial tears because they replace the missing water in the tear film of your eyes.
Dry eyes are caused to lack of enough good quality tears or due to evaporation of the tears form the surface of the eyes too quickly. This causes a deficiency of lubrication affecting the health of eyes. Common causes of dry eyes are ageing, side effects of certain medications, certain medical conditions, and hormonal changes.
