Strike King Pro Blocker Sunglasses can be a useful and important accessory for fishermen. The glare of the sun on the water can damage eyes and it is important to protect them while fishing. These Strike King Pro sunglasses offer excellent protection. They are 100 percent polarized and have side-panel lenses to ensure total coverage. This feature decreases glare from the water, thereby reducing eye strain and making it easier for you to see. They also block 100 percent of ultraviolet light, which is important, because repeated exposure causes damage. The Strike King sunglasses are also very tough. Because of a more rigid lens and state-of-the coating, they are scratch-resistant. In fact, they deliver more than twice the resistance offered by other lens material. They also repel water, dirt and dust.
