What's the science behind this? Obviously, like (nearly?) everyone else here, I make my living staring at a screen and if it's damaging my eyes, I'd like to know about that.

Similarly, does anyone have a pair of these lenses? Any good? Do your eyes feel any difference?

The energy of a blue photon is higher than a red one, and so an intense blue light might be an hazard [1]. That said, I don't think these glasses will help much, because according to their transmission curve they still transmit ~75% in the 470nm region (which corresponds to the blue emitted by "white" LEDs). If they had managed to make some kind of "optical notch filter" removing the ~470nm blue light from LEDs at a reasonable price it would have been pretty much an instabuy for me.
