I usually work about 10 hours per day online. About a month ago my wife and kids left for a few days and I decided to work a little longer. However, the first night I got dizzy and could not longer stare at the computer screen. It got so bad I couldn't even look at a computer screen for a couple of days.
I obviously don't want to repeat this again. I heart a lot of people claim they work 15 hour days online. How can I accomplish this without getting eye strain? Thanks
