Excellent!  Do just what they need to.
Wow!  I recently spent $600 on new glasses, and they are great -- Except -- I was pushing them up every few minutes and it took all the joy out of being able to see when I couldn't make them fit right and stay in proper position.  So, I did some searching for nose pads and decided to try these.  What a difference!  I got the 14mm ones, and the ones on my glasses were 15mm, but these, though slightly smaller, work just fine.  It was rather difficult to put them on my glasses, as the tab is soft (and I couldn't see without my glasses!) but once I got them inserted into the tabs, they are great.  The nose pads are soft, and grip well.  My glasses are very comfortable now, and no more pushing my glasses up constantly.
