Oh, I was given the impression that Lutina is the higher end lens with blue light protection. I was quoted for a lower end Tokai lens, also with blue light protection (I think it is BCC or something like that) but definitely not Lutina.
Hi bro,
Tokai Blue Coat (TBC) is the equivalent of Crizal Prevencia, Hoya BlueControl, Zeiss BlueProtect. It works by having just a layer of blue coating & filters out ~30% HEV(Blue) light.
Tokai Lutina is the improved version which filters out ~94% HEV(Blue) light. The other big players don't have such lenses yet.
