All Gill sunglasses are floatable, so if you drop them, all is not lost.
They feature UV protection and 100% glare free polarised lenses specifically designed for use on the water. Polarized lenses are made up of a number of functional elements ultra-carefully bonded together to achieve a high-performance optical product: The main element of the sandwich lens construction is the polarizing light filter in the centre.
Laminated to both sides of the filter are UV light absorbers, which block 100% of harmful UVA, UVB, and UVC radiation.
