Not worth the money - Carson Clip & Flip Clip-on, Flip-up Magnifying Lenses for Eyeglasses

I bought these for my mom, whose eyesight is not great. Thought the magnifier would make it easier for her to read. I tried them before I gave them to her and I couldn't see a thing, no matter where I held the object, neither close nor far away. Gave them to mom. Same result. She could see nothing. Had my husband try them. Same result. He could see nothing. Will be returning. Also, the clip on the magnifier was too wide. When I put them on my glasses, the clip was on the glass, not the nose piece.
