Whether its a clear or overcast day, muddy or clear water, the revolutionary Strike King S11 Optics Sunglasses will dramatically improve the anglers ability to see into the water and locate structure and fish. Scientifically Engineered Lens Colors - designed to heighten the human eyes ability to clearly distinguish underwater structure and fish in all weather conditions. Bi-Gradient Mirror Treatment - in addition to providing protection from direct sunlight from above, this special treatment also provides that extra protection from light bouncing off the water. Super Hydrophobic Coating - Repels oils, dust and water, preventing water spots and making the lens easier to clean. Anti-Reflective Coating - Prevents light from bouncing off the rear of the lens to the eye, resulting in a clearer, non-distorted image.
