Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision. The disease typically affects older patients; computer users often complain of dry eye symptoms. With each blink of the eyelids, tears spread across the front surface of the eye, known as the cornea. Tears provide lubrication, reduce the risk of eye infection, wash away foreign matter in the eye and keep the surface of the eyes smooth and clear. Excess tears in the eyes flow into small drainage ducts in the inner corners of the eyelids, which drain into the back of the nose. Dry eyes can occur when tear production and drainage is not in balance. People with dry eyes either do not produce enough tears or their tears are of a poor quality: • Inadequate amount of tears. Tears are produced by several glands in and around the eyelids. Tear production tends to diminish with age, with various medical conditions or as a side effect of certain medicines. Environmental conditions, such as wind and dry climates, can also decrease tear volume due to increased tear evaporation. When the normal amount of tear production decreases or tears evaporate too quickly from the eyes, symptoms of dry eye can develop. • Poor quality of tears. Tears are made up of three layers: oil, water and mucus. Each component protects and nourishes the front surface of the eye. A smooth oil layer helps prevent evaporation of the water layer, while the mucin layer spreads the tears evenly over the surface of the eye. If the tears evaporate too quickly or do not spread evenly over the cornea due to deficiencies with any of the three tear layers, dry eye symptoms can develop. People with dry eyes may experience irritated, gritty, scratchy or burning eyes, a feeling of something in their eyes, excess watering and blurred vision. Advanced dry eyes may damage the front surface of the eye and impair vision. Treatments for dry eyes aim to restore or maintain the normal amount of tears in the eye to minimize dryness and related discomfort and to maintain eye health. Dry eyes can develop for many reasons, including: • Age. Dry eyes are a part of the natural aging process. The majority of people over age 65 experience some symptoms of dry eyes. • Gender. Women are more likely to develop dry eyes due to hormonal changes caused by pregnancy, the use of oral contraceptives and menopause. • Medications. Certain medicines, including antihistamines, decongestants, blood pressure medications and antidepressants can reduce tear production. • Medical conditions. People with rheumatoid arthritis, diabetes and thyroid problems are more likely to have symptoms of dry eyes. Also, problems with inflammation of the eyelids (blepharitis), inflammation of the surfaces of the eye, or the inward or outward turning of eyelids can cause dry eyes to develop. • Environmental conditions. Exposure to smoke, wind and dry climates can increase tear evaporation resulting in dry eye symptoms. Failure to blink regularly, such as when staring at a computer screen for long periods of time, can also contribute to drying of the eyes. • Other factors. Long-term use of contact lenses can be a factor in the development of dry eyes. Refractive eye surgeries, such as LASIK, can decrease tear production and contribute to dry eyes. D r y e y e s c a n b e a c h r o n i c c o n d i t i o n , b u t y o u r e y e c a r e professional can prescribe treatment to keep your eyes healthy and comfortable and to prevent your vision from being affected. You can take the following steps to reduce symptoms of dry eyes: • Remember to blink regularly when reading or staring at a computer screen for long periods of time. • Increase the humidity in the air at work and at home. • Wear sunglasses outdoors, particularly those with wraparound frames, to reduce exposure to drying winds and the sun. • Nutritional supplements containing essential fatty acids may help decrease dry eye symptoms in some people. Ask your optometrist if taking dietary supplements could help your dry eye problems. • Avoid becoming dehydrated by drinking plenty of water (8 to 10 glasses) each day.
