My optometrist assures me that all polarized prescription lens will now also assure 100% UV protection. Is this true and if not how can I insure that I’m getting optimum UV protection from new prescription lens?

    I think it doesn't make enough difference because prescription has to do with the means of purchase, not the glasses themselves. Also, I would suggest that questions of the form "is my doctor correct about the thing he's certified in" are not appropriate for the site (although I'd be happy to discuss!)

    I agree with John here. To me questions putting a dr.s advice on their field against ours are silly for this site.

    This needs a geographical area. I doubt that the same rules apply in China and the US.

    I'm not sure this is a duplicate. Lenses are made of different materials than glasses. Voting to leave open.

    @Fran So please tell us if you mean lenses for glasses or contact lenses. BTW if the first, you can close (vote) your own question as a duplicate.
