As i'm getting older my body is falling apart!!! - Have been told i need glasses! Was planning on getting transition lenses with my glasses but I wanted to know if anyone else had them and what did you think about them? Worth the buy? (or should i call up and cancel??) I'm worried they wont go dark enough (like on the add) or that they may be a little tinted in my office (some natural light) So - what do you think?
