Thanks for writing this, Bill, for this is something many of us probably overlook. Monitors damage eyesight.
As a fellow who can spend up to 8 hours per day on a computer - sometimes more - I get very concerned. I often get up and go for a short walk, every hour on the hour.
Recently I installed a little application called f.lux which changes the brightness of my monitor at sundown. It softens the harsh glare and makes it - in my feeling - a lot easier to work with and just simply to look at, in the evenings.
It takes some getting used to - and you can turn it off for an hour to do graphic work (which I do sometimes, especially with screenshots). It does take some getting used to, and if you have different user accounts on your computer, the difference between using f.lux on one account and not on the other is stark. You really get hit by hard, harsh light when you switch away or turn it off to do some colour-intensive work.
Worth a look at for the concerns that Bill has raised below. Windows and Mac OS
