CVS (COMPUTER VISION SYNDROME)

What is CVS?

A complex of eye or vision problems which are experienced during and related to over use of computers, mobiles, laptops, tv`s etc. The problems supposedly linked to blue spectrum of light, and ranges from dry eyes to digital eye strain, sleep cycle disruption and even macular degeneration, which causes people to lose some or all of their central vision.

 

Should You Be Worried About Blue Light and Computer Radiation?

There is evidence that some kinds of light exposure can cause eye damage under certain conditions. For instance, too much exposure to ultraviolet light from the sun does raise the risks of eye diseases, including cataracts, burn in the retina (solar retinopathy) etc.

Long hours staring at digital screens can cause eye strain, and decreased blinking associated with computer use can cause dry eyes. But these effects are caused by how people use their screens, not by anything coming from the screens.

You can protect your eyes from strain if you work with computers all day.

Sit about 25 inches (arm’s length) from the computer screen. Position the screen so you are gazing slightly downward.

Reduce screen glare by using a matte screen filter if needed.

Blink your eyes frequently so that tear film stays on your eyes

Take regular breaks using the “20-20-20” rule: every 20 minutes, shift your eyes to look at an object at least 20 feet away for at least 20 seconds.

 

Every 50 minutes on a computer, change tasks for 10 minutes.

When your eyes feel dry, use artificial tears to refresh them.

Adjust your room lighting so that light reflection won`t fall on your screen and try increasing the contrast on your screen to reduce eye strain.

If you wear contact lenses, give your eyes a break by wearing your glasses.

Many eye symptoms caused by computer use are only temporary and will lessen after you stop using the computer.
