Product review (4 stars): ... expensive paperweight since my choice of frame wasn't the best and the optician couldn't seem to make them fit ...
I was ready to think of my new glasses as a very expensive paperweight since my choice of frame wasn't the best and the optician couldn't seem to make them fit right. Just when I was ready to give up, these anti-slip retainers have made my glasses functional again so I don't have to buy another pair of glasses. I can adjust them precisely since with my heavy prescription and progressives a millimeter off makes a big difference, and they're quite comfortable. They work just like in the picture (which is good since they didn't come with any instructions). The only down side is getting the glasses on and off my face, but it's worth it not to have to be pushing them up and readjusting my tired eyes all day (I was getting a lot of headaches!). I plan to purchase another set of these as backup just in case, but they seem to be stuck on there very well.
