I wear a lot of Cheater glasses and these were by far the worst I have ever encountered. The price was attractive because I lose a lot of pairs. The glasses seem well designed and light on my nose but when I went to clean them the lenses ALWAYS popped out. Extremely frustrating to try and maneuver the lense back into place then again I would try to clean and POP goes the weasel. The manufacturer needs to seriously look at this major flaw and fix it before anymore of these rob 5 minutes every time you need to clean the glassed.
