Put them in the freezer overnight. That's what I have to do with my prescription transition glasses. They get good and dard after that.

 

I have had my Wylie X Gravity for 90 days. USELESS is the word that comes to mind. They don't seal, they don't darken, and they are FUGLY. Just contacted Wylie X to ask for a refund, waiting on the response.

Now I find it interesting that no where in the instructions/papers that came with the glasses does it mention putting them in a freezer overnight. If they were even remotely attractive I would try it, but my 8 YO points and laughs when I put them on and says she is so embarrassed to see me wearing them that she runs away.
