These days,many of us have jobs that require us to stare at computer screens for hours that can put a real strain on the eyes.
Eye problems caused by computer use fall under the heading computer vision syndrome (CVS).Research shows that between 50%-90% of people who work at a computer screen have at least some symptoms.
Working adults aren’t the only ones affected,kids who stare at tablets or use computers during the day at school can have issues too.
HOW DO COMPUTERS AFFECT VISION?
When you work at a computer,your eyes have to focus and refocus all the time.They move back and forth as you read.you may have to look down at papers and then back up to type.your eyes react to changing images on the screen to create so your brain can process what you are seeing.All these jobs require a lot of effort from your eye muscles.And to make things worse,unlike a book or a piece of paper,the screen adds contrast,flicker and glare.
You are more likely to have problems if you already have eye trouble,if you need glasses but have not gotten one or if you wear the wrong prescription for computer use.
WHAT ARE THE SYMPTOMS?
-Blurred vision
-Double vision
-Dry,red eyes
-Eye irritation
-Headaches
-Neck or back pain.
If you don’t do anything about them,it could affect more than your eyes,you could also have issues with your work performance.
HOW IS IT TREATED?
*SPECIAL LENSES:
Special lenses called transition lenses with AR(anti-reflective),can be prescribed by your eye doctor after examining your eyes.these lenses help to neutralise the rays from the screen and excess light(brightness).
*CUT THE GLARE:
Change the lighting around you to reduce the effect on your computer screen.If light from a nearby window casts a glare,move your monitor and close the shades.Buy a desk lamp with a moveable shade that casts light evenly over your desk.You can also add a glare filter to your monitor.
*REARRANGE YOUR DESK:
The best position for your monitor is slightly below eye level,about 20-28 inches away from your face.you shouldn’t have to stretch your neck or strain your eyes to see what’s on the screen.Put a stand next to your monitor and place any printed materials you are working from on it.That way you wouldn’t have to look up at the screen and back down at the desk while you type.
*GIVE YOUR EYES A BREAK:
Follow the 20-20-20 rule.look away from the screen every 20 minutes and look at something around 20 feet away for about 20 seconds.Blink often to keep your eyes moist.if they feel dry,try some eye drops(artificial tears).
*TWEAK YOUR SETTINGS:
You don’t have to live with the factory -installed presets if you are uncomfortable.Adjust the brightness,contrast and front size until you find what’s best for you.
