There's also a program called F.Lux that adjusts the blue component of a computer monitor automatically based on time of day (ramps down blue at night).

DW just got new glasses and had the option to get lenses with blue reduction. I'll try to find out more and pass that on.

Thanks for this. I am buying a pair immediately. If it works, you are a Saint.

My job used to have me in front if a compute 10 hours a day. Getting a prescription that was calculated to the distance from my eyes to the computer screen was a GREAT change. So was no longer having to go in to the job.

When I'm at the desktop PC I use my regular reading glasses. I used to use lower strength for this but then I found that I needed to be close to the screen to get the ergonomics right (particularly my back). The chair is also an important ergo item for me. I have the cordless keyboard on my lap and this puts my eyes, hands, wrists, and back in the right position for me.

So I'd say all this depends on your setup and your body. Not easy to generalize.

And thanks for the idea. I think I might really like some dedicated computer glasses, so I ordered some cheap ones from Amazon just to try out this idea. I have the prescription from my last eye exam, so I ordered them with half the reading correction.

How did the cheap glasses from Amazon turn out for you?

For me I got some good news with those scratches I put on my glasses with a microfiber cloth. Apparently, maybe they weren't scratches but superficial smudges as after no longer using a cloth but just dish soap and water to do the cleaning, I really can't see any scratches at all

That's what I have also. Not particularly expensive. I can see fairly well with them although they are a few years old as this point...
