Did you try Sunglass Hut? They have tons of sunglasses and all different tones for the glass.
Sunglass Hut won't have them. Coppertone lenses are only offered at optical shops, not mass merchants like Sunglass Hut. If you don't know what you're talking about ( I doubt you have actually heard of Coppertone lenses, know who makes them, know what's different about them, or where to get them) don't answer.
