I have a friend who bought a pair of glasses whose lens are capable of changing colors in different environments. For example, they become black in the bright sun.


Hi,
Does the above sound right? Correct me if I am wrong. Thanks.

    I think your sentences are fine, JGM, with the change of "lens" to "lenses".

    A shorter version would be "My friend bought a pair of glasses with photocromic lenses".

    My only concern would be "changing colors". The lenses aren't green indoors and blue outdoors, or brown indoors and purple outdoors. Somehow "changing colors" makes me think of a variety of colors rather than a lighter/darker difference because of tinting.

    I agree with James M. The lenses do not "change color"; they "change" or "adjust". It also is not "different environments" that makes them adjust, but different lighting conditions. I would tend to say "They become darker in bright light."
