Fishermans sunglasses make tying your hooks easy. The lenses are UV400, polarized and have built in bifocal lenses. The lenses are more pronounced on these glasses and are made for fishing. The lenses come in a polarized gray or brown. We have heard that ocean fisherman prefer the gray lenses and fresh water fisherman prefer the brown lenses. We are usually out of the brown, so if you see them available, grab them. This frame fits most people and is very comfortable.
