did you opt for their scratch resistance lenses? because all they do is actually add a coat of so called "Anti Scratch" coating on top of the lens.

when it's new it's pretty good, however after few years the coating starts to come off and you get those "scratches" & "fogs".

the more often you clean the glasses the faster they come off.

so i only use non-coating lenses.

if you want scratch free, go for glasses but they are heavier & more expensive & fragile. but they offer the best clarity compared to plastic which would also turn yellow over time but you won't notice it just cosmetics.
