Blu-Tech Lenses ??? Anyone heard of them?
http://www.blutechlenses.com/
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).
What is really new? ..................................

Is there anything really that seperates this from Blue-Blockers ?
Same thing.......................I introduced and advertised Blue-Blocker dyes first time in 1984, demonstrated them at numerous Optifairs and VE East and West as well as OLA's and never would have dreamed that they would become a novelty just about 30 years later.

At he time the school of Optometry at the University of London Ontario made a full study of Blue Light blocking lenses paid for by the Canadian Government. I still have a copy.
You can actually do them yourself in your own dye pot or microwave without having to pay for the latest technology in optical lenses.
