Review on ProSPORT BIFOCAL Sunglass Readers Men Women Blue Light Blocking HD Amber Lens Semi-Rimless Wrap-Around Golf Driving by Ryan Cornelison

Overall I am happy with the glasses.I needed to be able to look at maps out on the trail without having to rummage around in my pack for my glasses.

The bi-focal part is not optical grade, but what do you want for $20? Also, it may take some time to get used to the bi-focal, so use them a couple days before you pass a negative judgment.
