the lenses are a little bit more clear than another brands, it supposed to protect an 100% of 100% UVA/UVB rays but dont protect at 100% of common light, i mean my eyes dont rest of the sunlight as with other brands like oakley or wiley x.
i have owned other brands and i can recommend it in this order:
1.- wiley x
2.- oakley
3.- ess
if you want eye protection and a good looking pair of sunglasses buy a WILEY X, if you want a more fashionable pair of sunglasses buy OAKLEY, and if you need more security for your eyes but you`re not on high sun conditions buy ESS
Pros: good looking, comfortable and resistant sunglasses
Cons: don´t protect at 100% of the sunlight
