Eye Pro 2.1 is an interesting tool which uses several techniques to try and reduce the chance of eye strain when you're using a PC.
Looking at a monitor (or any other close-up object, actually) for a very long time can leave your eyes feeling tired, for instance, so the program will prompt you to take regular breaks. Nothing major - just a short break of 8 seconds every 15 minutes, and a longer break of 1 minute every 45 - but that's enough for you to focus on something further away for a while, which could make all the difference.
Eye Pro 2.1 also provides "screen filters", coloured overlays which appear over your desktop. If there's a lot of bright blue on the screen, for example, the authors say applying the blue filter should neutralise screen glare and make your system more comfortable to view.
A "Vision Therapy" section provides various simple animations and games which the authors claim may improve your eye health. You can watch a ball bounce around the screen, for instance, or try to see the image in a 3D stereogram.
And a handy "Usage Stats" section tracks and reports on Eye Pro's effectiveness, by highlighting how often you take short breaks, and how many times you skip them.
Eye Pro 2.1 probably won't help you get rid of your glasses, then, but it is a versatile program with a lot of options, and if you're concerned about the effects of lengthy PC sessions on your eyesight then we'd certainly give it a try.
