Without Gunnars I can look at a display for 5 hours before eye strain sets in, with Gunnars I can look for 12 hours. So either they used shoddy lens/filters or I am just special somehow.

Placebo effect, maybe?

  Maybe. We also need to know whether they have a non-tinted but still "computer glasses" control. I think computer glasses have other tweaks specifically for viewing screens.

Well Gunnars are actually amber tinted. At the end of TFA it says, "Filtering out higher levels of blue light would require the lenses to have an obvious amber tint, which would have a substantial effect on color perception." This implies that they studied lenses that aren't tinted, which obviously can't be that effective...

  > which would have a substantial effect on color perception. Our vision system is pretty good at compensating for white balance. What I've noticed is with reduced higher wavelengths, my visual acuity drops substantially. These glasses may not improve sleep quality, but my experience is that it increases sleep quantity as looking at a white display keeps me awake longer like it's still daylight hours, where as with reduced blues my body tends to think it's near bedtime and I do tire and hit the sack sooner.

    Yeah exactly. The way I explain it to people is that the orange light lulls you into wind down mode the same way that stepping outside on a sunny morning peps you up.

Try lowering the brightness of your monitor.

My screen glasses help with eye strain, but they were $80 and not $15. The orange backlight in my Kindle is also easier to look at in the dark than the white backlight. Maybe it works for some people and not others.
