What’s PYV (Protect Your Vision) ?

PYV is a free online application aimed at protecting eyes from a Computer Vision Syndrome (CVS).

What’s CVS ?

CVS is a syndrome which affects about 70% of the people in developed countries. They experience eye discomfort and vision problems when viewing a computer screen for more than 2 hour daily. The level of discomfort appears to increase with the amount of computer use.

The most common symptoms of CVS are:

  • eyestrain
  • headaches
  • blurred vision
  • dry eyes
  • dry, irritated eyes
  • double vision
  • difficulty refocusing the eyes
  • neck and shoulder pain

If any of these sounds familiar to you it’s about time to take care of your eyes.

How to use PYV ?

Switch on PYV every time when your're going to use computer for more than 2 hour.
Simply go to www.protectyourvision.org website and click "Start PYV".

You can choose between 3 different modes:

  • 20-20-20 – after every 20 min spent in front of a computer a 20 sec break is signalized with a sound alarm and notification. In this time focus the eyes on an object 20 feet (6 meters) away
  • 60-5 - after every hour spent in front of a computer a 5 min break is signalized
  • Custom – define by yourself break's frequency and length

Find out which mode suits you.
During the break avert your eyes from a computer screen, close them or do eyes gymnastics.

Enjoy healthy computer use.
