Never really bought too much into the whole “gaming glasses” thing. But after having tested some Gunnar Optics, I had to try a pair of my own during long gaming sessions. With the Gunnars being quite expensive (for potentially no visible benefits), I decided I'd try a cheaper pair, in the case they didn't live up to expectations.
Pleasantly surprised by these, as since using them, I am unable to endure long gaming sessions without using them, due to the strain on my eyes without. These are comparable to using Night Mode on an iPhone, where it dims the harmful blue light. I would definitely recommend using these or similar pairs if you already having issues with eyesight (I am shortsighted, saves what little eyesight I have currently).
Also getting more NoScopes in CSGO, not sure if related or not. A++ would noscope again
