Hello,
I am working at a start up company that will soon be making sunglasses and I have a few questions that you may be able to help me with.

First, who are some of the trusted suppliers who can provide non-corrective UV protection lenses? (Feel free to correct my terminology.)

Next, is it possible to hire a 3rd party to grind the lenses into the appropriate shape for the frame they would inhabit? At some point we'd like to buy our own grinder but it would be nice to put that off until we needed it.

And finally, I believe that CR-39 plastic lenses are good for typical fashion sunglasses. Is this true?

Thanks for your time and help.

Gary
