The ophthalmologists who investigated the "Effects of Computer Visual Display Terminal on the Eye" both on a controlled and uncontrolled groups of persons found that continuous exposure of the eyes to the computer screen is greatly injurious to the eyes as well as the whole body.
The eye experts, led by F.G Adepoju found that the surge in eye irritation, backaches, neck pains and wrist aches are not unconnected to Computer Vision Syndrome(CVS).
Hence, to preserve your eyes from these digitally-related diseases, below are 9 tips on preventing them.
1.Sit far enough away from the screen. This is usually considered at least an arm's length away from the screen.
2.Locate the computer screen 4 or 5 inches below your eye level. This ensures that more of your eyeball is covered by your eyelid, keeping your eyes moisturized and healthy.
3.Locate reference material properly. If you're using any books or papers while working, you can strain your eyes if you don't locate them properly. To help do this, use a document holder or a book to prop up materials a few inches and help rest your eyes.
4.Blink often. We naturally blink about 20 times every minute, but when focusing on a screen this can drop by as much as half. This means your eyes are at much greater risk of drying out when working on the computer.
5.Adjust your screen lighting. Your screen should be illuminated in relation to your environment. If you're working in a brightly lit room, you can increase your brightness settings; if the room is dim, lower the settings. While the screen should be brightest object in the room, it shouldn't be on the brightest setting in a dark room.
6.Reduce glare from your screen. Surrounding lights can reflect off your screen and strain your eyes. There are several ways you can reduce glare and keep your eyes healthy.
Keep your computer screen clean. Dust on your screen can further reflect light into your eyes. Dust your screen on a regular basis with either a specialized cleaning cloth or spray.
7.Take regular breaks. The American Optometric Association recommends that for every 2 hours of looking at the computer screen, you should take a 15 minute break. During this time you should blink, close your eyes, and allow them to rest and re-lubricate.
8.Ask your eye doctor about specialized glasses. Some glasses are specifically tinted to reduce glare from computer screens. You eye doctor can recommend a good pair of these that will help properly protect your eyes from computer glare.
9.Stop working if you experience symptoms of digital eye strain/computer vision syndrome.
