With a retro look that's too cool for school, the Suncloud Fairfield Sunglasses add instant appeal to any wardrobe combination. Made with Grilamid TR-90 Nylon, the injection-molded frames are sturdy yet flexible. The polarized lenses feature a gray tint that does not alter objects' true color, so you see the natural environment as it is. Polarization filters out horizontal sun rays that travel horizontally, which blocks painful glare and eases eye strain. It also enhances your view, letting you see more details.
