All polycarbonate lenses block UV inherently. Acrylic plastic doen not unless treated. If the poly carbonate hald is treated then the UV blocking is enhanced. This is without tinting. Add tinting ro block visible light.
Any reasonable sunglasses will state the UV protection and almost any polycarbonate lens glasses will be over 95% whthout ocating or polarization.
Add polarazation if you want it. Filters to block the blue haze will help visibility.
Personally I have a set of 40 year old Ray Ban Aviators with another new set of lenses. Polycarbonate, tinted with Cryzal coating and I am delighted!
I liked then so much I ordered a new 3029 s and clear lenses mad exactly the samw with the caotings ets. Since they are Polycarbonate they will be over 95% UV blocking eventhough they are clear.
