Costa 580 Lens
Yellow light is the enemy on the water and on land. It's hard for the eye to process, and changes how you see the world. Costa 580 Lenses cut down on yellow light, allowing the eye to see more red, blue, and green. The result is purer vision with unmatched contrast, definition, and colors.
Blue Mirror Lens is made for the open water. Delivers maximum contrast and color in full sun while eliminating glare. Allows a minimal 10% light transmission.
