Polaroid sunglass, full UV protection with the added benefit of polarised lenses to reduce glare.

What Polaroid say about the Polaroid lenses -

"When light reflects off shiny surfaces, such as sand, water, snow or tarmac, it is diffused in horizontal and vertical waves: the first allow the human eye to visualize colours and contrasts, while the latter only produce reflections. The glare affects visibility, making it difficult to sunbathe and dangerous to drive, cycle or ski. While non-polarized lenses just darken what you are looking at, sunglasses with Polaroid polarized lenses ensure more comfort and less glare. Thanks to their anti-glare properties, our lenses can be worn all day, every day, to live every moment in style, safety and comfort."
