A good pair of fishing sunglasses are all about protection and not fashion. They serve as a protective guard to keep the eyes safe during fishing while the hook flies through the air. The right fishing sunglasses also offer UVA and UVB protection. These properties help protect the eyes from the constant rays from the sun, which could lead to eye damage and cataracts. Also, by blocking out the glare from the sun, you can see better, and your chances of reeling in a catch are higher.
