This is a copy and paste from another reviewer but I had the exact same experience with these glasses. If you need glasses with magnification, I think that means the lenses have to be distortion free. Those were very bad points, blue blocking doesn't hold up. If you looked at anything off center there was a very noticeable distortion that I have never experienced with other loupes including Revain or those bought from a local store. I wore them for about 2 minutes, took them off, went back to another pair without the blue lock and initiated the return process.
