Not that this is super relevant to the thread, but for those who are curious what it's like to have these on, consider installing flux.
Who knows, might save you some money instead of buying the glasses themselves (note: wait until sundown to actually see the effect, or configure it yourself but it looks kinda ****ty when sunlight is involved).
flux is actually a great tool. I don't use it but I'm a fan of it and it works if you're not a professional night-owl and keep more normal hours.
However, Gunnars are complete snake oil. They're merely a tinted lens and nothing more (and I have cheaper lenses available in similar tints in a much more stylish sunglass frame that I use where it matters: cycling outdoors in traffic).
All the claims about moisture are merely based on the fact that you're wearing glasses and your face will sweat more around them. You can get eyedrops and get all the real benefits of Gunnars without looking stupid wearing non-prescription eyeglasses indoors. You can make a lifetime's supply of your own eyedrops for a fraction of what these things cost.
That's not to say not to get them. Some people like how they look and that's cool and this is a good deal...but there's really little to no medical value in these things.
