IT WORKS!!  Magical!
Nerdwax is AMAZING!  I bought a new pair of prescription glasses, which I had adjusted three times because they kept sliding down my nose and nothing worked to keep them in place until I bought Nerdwax. I even used it on my glasses when I went to a water park and the one application lasted all day even after the glasses ended up under water a few times. I'm so happy I saw this on Sharktank and decided to give it a try.  A++<br /><br />NOTE: Based on other reviews, I wiped my glasses off with cleaner before applying.
