Bests & Worsts Reviews from Amazon

Bought these as a birthday present for my husband. He likes them, and, taking a color-blindness test, they dropped him from extreme deutan without glasses to mild deutan with them (he was medium deutan when he wore my polarized sunglasses by accident). I do think it's worth noting that they came with a note offering $20 for good reviews, which feels a little dishonest and makes me skeptical of the high number of reviews that make them sound miraculous. To be fair, they might work better for someone who was not so strongly deutan, but there's a chance some of the reviews are exaggerated in exchange for $20. Overall, worth a shot if you're red-green colorblind and want things to look more crisp and distinct and see a slightly improved range. Nobody cried or anything.
