After watching video .....the stuff is sprayed on
On sun lenses i think it would leave a film on the surfaces and you could not see through them
If you were to wipe off the sprayed on product to see through the lenses it would smear them
If you were able to clean the lenses to see through... then the product would not be on the lenses
I could be wrong
Go buy it at Home Depot and test it for us
As an optician we sell all type of optical lenses with built-in super hydrophobic finishes
It is built-in the matrix of the lenses.....not just a surface coating
Has a 2 years unlimited scratch warranty...no questions asked
The "beading" only wears out 3% even after extensive testing of 20,000 cleanings !!
It has the highest water repellent angle available of 116 degrees
Crizal Sunshield UV "process" will add about $100 to the cost of the sun lenses
So make sure not to never lose those sunglasses or you will cry

Crizal cannot be added to existing sun lenses
Crizal type lenses are custom made and can be ordered through authorized optical stores
Crizal Sunshield UV makes the backside of the lenses non-reflective....for the clearest vision
