Not OP, but I've bought a dozen different blue light blocking glasses, including the fancy $100 ones from Gunnar Optiks. Gunnar had good performance, but no better than the $12 cheapo pair I got off Amazon (no doubt from a reseller of generic Chinese wares). Save yourself the money and go with a cheap pair to see if you like it. You can always invest more later if you find it to be worthwhile, but in this case price did not yield any appreciable difference to me.
