Prevention of Computer vision syndrome
Computers are indispensable to our everyday life hence one must counteract vision problems with appropriate measures.
Dr. Parul M. Sharma, Senior Consultant Eye Surgeon at Max Hospital gives us following steps to reduce eyestrain:
• Computer screen should be at least 20 to 30 inches away from your eyes while the television should be watched at a distance of 3.5meters.
• Arrange the monitor so that the top line of on-screen text is at eye level. Arrange brightness and contrast to minimize glare and reflections.
• Remember to blink often while working on a computer. Most of the times, one unconsciously blinks less frequently in a bid to focus more. Blinking is essential as it coats the eye’s surface with a tear/moisture film thereby preventing dryness. One should consciously make blinking a normal practice while working on a computer.
• Take frequent vision breaks to rest your eyes, close your eyes for few seconds every 10-15 minutes. This also rejuvenates your tear film which otherwise gets compromised due to decreased blinking rate.
• You can ask the doctor to prescribe a safe lubricating eye drop if the eyes feel dry and itchy.
• The lighting around your work desk should be appropriate to prevent eye strain. Light should not reflect off your monitor and the source of light should be from behind where you sit.
• Computer ergonomics should be heeded to. The monitor should not be too high or low for the eyes to focus on. The computer display should be at a reasonable distance.
Eye exercises can also help to reduce eye strain and make the eye muscles relax.
