Ryders’ Seventh Photo Brown Lens Sunglasses come with a large dual lens design that offers a huge field of vision with an injection molded polycarbonate lens construction that offers fantastic impact resistance. The lenses also offer full UV protection. Specially positioned and designed the lenses are optically correct to diminish distortion for a restful vision experience that reduces eye fatigue. To keep the lenses clear they come with a hydrophobic and oleophobic coating which stop water from pooling on the lens and stops the creation of water marks. Also keeping the lens clear is a scratch resistant coating. Photochromic lens technology automatically adapts the lens’ coverage to suit changing lighting in your environment. For example, in bright lighting environments the lens will darken. Meanwhile, in low lighting environments the lenses will lighten. The bold, half-rim frame is constructed from Grilamid TR90 which keeps the sunglasses lightweight and flexible whilst also retaining a great level of strength. The sunglasses come with adjustable nose pads and temple tips that are coated in a hydrophilic rubber which keeps the glasses in position.
