I come across a video showing blue protective lenses reflecting UV radiation into the eyes https://www.youtube.com/watch?v=KCiTMOd7iEw&feature=youtu.be
A thread talking about it http://www.optiboard.com/forums/sho...-s-Bluecontrol?p=510318&viewfull=1#post510318
Seems like they are saying that lens coating on the side near the wearer will reflect UV into the eye. Now I am wondering if the blue protective lenses actually harms the eyes more.
Brudder... seems like the salesman never explain to you that essilor prevencia is coated on the outer surface and not the inner lens surface so harmful blue lights are not reflected back into yur eyes. Hoya blue control has both sides coated though. Not sure abt zeiss. To me the choice is very clear. Essilor is also the cheapest among all for my prescription.
