They claim they block more blue light. Ok, any yellow lens will.
They also claim that blue light causes AMD? Anyone else heard of that? I know that AMD is still a mystery to some degree, but is there a study that substantiates that claim that blocking blue light we can prevent AMD?
No real information on the technology. HOW does it block blue? Revo used oxides in the day, to block short wave blue.
They are distrubuted by Signet Armorlite (which means Essilor).
