WYCO lenses are fully polarized with UV400 protection for your eyes.
Lenses can be removed by pushing from the inside out on the lens (lenses will not pop out towards wearers eyes, for safety reasons). To put new lenses in, just align the lens on the front of the frame and slowly work your way around pushing the lens into the groove of the frame.
It takes a few tries to master but once you do, you will be swapping lenses with ease.
*Please Note: This item is for a single pair of lenses. Images of full shades are for presentation purposes only.
