I wear the new type of eyeglass frame that is metal but the arms are a bit thicker than the older "wire" frames. Maybe that is the problem. These overframe feel uncomfortable and let unfiltered light in the bottom. I also have the much cheaper polarized overframe called Polar Shield which work just as well. Maybe it is my imagination but the polarization on all my new (last 5 years at least) glasses do not seem to work a well as the I remember the older ones did. Don't waste your money on Cocoons, buy the cheaper brand, not a lick of difference.

I also have prescription polarized sun glasses. While the fit is great the polarization is mediocre as noted above. I have the "bubble type" which distorts somewhat. I wanted overframes as a backup.
