Note that the FAQ on EBD's website lists their lens material as "CR39 Polycarbonate". CR39 and polycarbonate are not the same thing. For an explanation of the different common lens materials, go here: http://en.wikipedia.org/wiki/Corrective_lens#Lens_materials
It appears EyeBuyDirect uses CR39 for all their lenses. It's a fine material, and has the best optical quality, but don't order from them if you require the impact resistance of polycarbonate (ie. for kids' glasses or safety eyewear). The exception to this may be their "sport" glasses -- I have no idea what the outer shield on those is made of. It looks like the inside lenses will still be CR39, though. --~--~---------~--~----~------------~-------~--~----~ Check us out at the oft-updated http://www.glassyeyes.com!
