I've been using yellow tinted Gunnar glasses for about 5 years (wearing them now as I'm typing this)- they do help a lot with eye strain reduction.

Prior to wearing Gunnars, I'd often have headaches by 4 pm and my eyes felt dry and quite tired. I was sceptical in the beginning, but these things do help.

Easily the best $140 that I spent on ergonomics.

I use them for the past two years and can confirm I don't have problems looking at monitor for 12h if necessary anymore. I bought the cheapest ones just to test if I see any difference (at that time around $40) and it seems to be having a surprisingly positive effect on me. The only problem is when I am producing visual art - they have to go away when I am adjusting colors or the results are too cold ;-)
