Hi, I wondered if someone could help. I am looking for a replacement lens for the uvex cro pro sunglasses. But I am not sure of the one I need. I can't tell from the photos when I do the search so think I need the name. I have the clear and yellow tinted ones it's the dark tint ones that I need. I think they are the silver ones but need to be sure. Anyone know ? Thanks for your help in advance.
