Every purchase comes with a pair of polarized sunglasses, along with a box, a polarization test card, and glasses rope. These sunglasses work great outdoors and provide UV400 protection. These are great for any outdoor activities but some variants such as the brown have special attributes (see below). The blue and orange lenses have the most polarization of the three options.
Brown Lenses Specifically:
The brown polarized lenses work best in low light. The brown polarization offers good visibility in the sun and overcast. A majority of lake bottoms and river beds are brown/amber colored from dead algae, sand, and mud. The brown lenses will allow you to see more fish in these conditions.
