Callaway Merlin Sunglasses

Technologically advanced and stylistically spot on. Look better, see better, and play better with this modern, stylish design complete with a sleek matte finish. Add in Callaway's unique P2X lens technology and Merlin is magic.FeaturesP2X Lens Technology - How It Works:• Contrary to conventional thinking, these lenses actually let in more light [twice as much] than ordinary sunglasses.• More light means better depth perception, which is especially helpful around the green when reading putts and chips.• More light usually means more glare, so Callaway added a polarizing filter to counter this effect. Then they added a blue-green flash mirror to better manage confusing short wavelength light.• Finally, they designed lightweight frames that maximize adjustability, comfort and protection while fully exploiting the benefits of our technologically-advanced lenses.• Polarized lens blocks glare & lets in twice as much light for more visual comfort• Including Lens Cloth, Carry Pouch, and Hard Case with hanging clip• Provides 100% protection from UVA, UVB, UVC rays• 8 Base lens configuration keeps eyes covered from UV rays
