Review on UV Protection Photochromic Sunglasses for Men and Women: Ideal Bike Glasses by Mike Bigglesworth

*cm. Photo*10+ minutes in direct sunlight and in the dark. I've tried it early in the morning, afternoon and evening. Sure, it didn't take long for them to be "dark," but they're not very dark at all. *MAYBE* They got rid of the super-sharp brightness, but glare was still an issue. Due to the fact that they are "photochromatic", they are terrible. They are light and not uncomfortable. They do stud however. Especially in the morning and with a well ventilated helmet (Bell Super R3). I never had any fogging issues until I put them on. There are many photochromic lenses. avoid them.
