Eye Dr. AKM Mamunur Rashid founder of Dry Eye Center, Bangladesh. Dry Eye Center for detecting problems with tear production and evaporation of long time computer users, contact lens users,women above 45 yrs, aged persons had cataract surgery and people with Meibomiun Gland Dysfunction. Dry eye is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. It is accompanied by increased osmolarity of the tear film and inflammation of the ocular surface. Computer users more than 4/5 hours per day are requested to be serious as working on computers is visually demanding. It is therefore likely that individuals with minor vision related problems, that don’t produce symptoms under normal conditions, may find themselves symptomatic in this high demand situation.Common Symptoms you may have: • Eyestrain • Eye fatigue • Dry or irritated eyes • Blurry vision • Light sensitivity • Headaches • Contact lens problems • Red eyes
A decreased blink rate and increased tear evaporation (very commonly caused by the poor air quality of many work environments) can cause/ exacerbate dry eye in computer users. Studies have shown up to a two-thirds decline in blink rate during computer use. The normal blink rate averaged 21-22 times per minute as compared with 6-7 times per minute while reading a computer screen. Reduced blink rate isn’t just a phenomenon of computer use. The blink rate slows any time an individual fixates, or stares, for prolonged periods like watching television, reading a book or driving a car. By contrast, computer users gaze straight ahead with their eyes fully open exposing twice as much of their ocular surface thus allowing for greater evaporation of their tear film. Treatment for computer related dry eye follows the same course one would pursue for other forms of dry eye.
