For myself, it was my optometrist's idea. I get one "free" pair a year from my vision coverage, and when a year rolled in where my old prescription hadn't changed much, he suggested getting computer glasses instead.

My only problem is forgetting to change glasses when I go out, and not really noticing til I hit a main road and wonder why the street signs are blurry.

I'm so near sighted, I wouldn't make it out the door without my glasses :-)

Have you tried the 'blue blocker' type lenses? If so, how do you like them ?

Not the person you're replying to, but I've had the blue-blocker (I think Costco calls them 'computer lenses' confusingly). They do shift colours towards the yellow range, but not as much as the computer "night shift" (so that the rest of the world looks normal) :) I've found that I can sit at my computer for longer, compared to when I didn't have blue-blocking lenses. It's probably just personal preference :)

I'm also very nearsighted :)

I've heard that blocking blue light can help you sleep better...And I'm usually on the computer before bed. Have you noticed any difference w.r.t sleep ? Thanks!

That's interesting. In the UK, it's pretty much standard. In fact I think (IANAL) that employment law mandates that the company has to pay for your amusingly-named "VDU" glasses if the majority of your work is in front of a screen and the optometrist says you need them. I got some recently and it's changed my life after several uncomfortable years of peering at odd angles through varifocals.

That's what worried me about it...having to move my head too much in order to see the screens. I have big lenses that let me use my peripheral vision naturally.

I hate bifocals. Hate them. Hate hate hate.

I've got the computer glasses, and then the regular ones. I swap as needed.

I've not had to try them yet. I'm not looking forward to it. Seems like it would be unnatural/tiring.
