I love this one..........................................
To all of you guy's and girls in the optical retail that are doing that...............are cheating the customer and themselves.
Water clear UV treated lenses do not absorb UV to 400nm.
Clear UV stops absorbing UV A at 382 nm and does not even go to 400nm
Every lens made these days absorbs all UV B up to 360 nm. Every lens manufacturer ads this UV absorber so lenses will not yellow by exposing them to daylight.
By treating the lenses with a clear UV solution you will protect the customer only half way to the full 400nm protection the customer expects. So there is nothing to be proud of.
There is only one nearly clear UV Solution on the market that does make it to 397nm that I know of.
