Their photochromic lenses don’t get dark, they just give it a bit of tint, about 5% change in color, if that. Might as well get the clear lenses. Their customer service is horrible, and most of all, They refuse to accept any return even with valid reason to return. Their only reason for denying a return is because it’s custom made (prescription) that’s why no return is accepted. The lenses were purchased with the expectation that the lenses will change colors as advertised, even with their false claim of fast delivery, but to receive an item that is not as expected or not as advertised, a return is necessary. Better to spend more elsewhere with a guarantee of decent product as advertised than waste money on this company. They even pretend to resolve the issue, but 3 weeks later, still no promised partial refund as they refuse to accept any return.
