I personally wear contacts for my pitiful eyesight; even getting 12" away from the monitor, I can't read anything without my contacts, even with Firefox on highest magnification. With correction, I have 20/25 vision, but I still sometimes get eyestrain and can feel my eye muscles going limp/lazy/cross-eyed when I'm staring too much at a monitor or TV, and I wonder if perhaps these sort of glasses might help.
However, I didn't quite grasp what the glasses actually did for him, or what they offer to the wearer; is there a better explanation someone wants to offer?
I'd like to hear an answer to this, too. Could it be the magnification? Basically, do these things just work like very low-power reading glasses (say, +0.25)?
It seems like making everything yellow is like dropping out the brightness a little and reducing the contrast. I feel like I could adjust my monitor to do this.
