Computer Glasses & Treadmill Glasses 

I use a treadmill desk. Some people like them because walking slowly, 1-2 miles/hour, is better for you than sedentary sitting. And walking slowly is easier than standing which can be fatiguing. Other people like treadmill desks because they claim to think better when walking. When I sit in front of a computer monitor, I seem to be about 19″ from the screen. When I use my treadmill desk, I’m something like 39″ from the screen. Hence I have 2 different “computer glasses” prescriptions. If you want to know what the numbers are about, check out the cool, mouseoverable What Does Your Prescription Mean? at All About Vision.com

Computer-Computer – this prescription is slightly sharper in front of a monitor, and just barely less sharp on the treadmill
