Bifocal sunglasses are sunglasses with built-in bifocal reader lenses for reading outside. All of our sunglasses with bifocal lenses are rated UV400 protection. Bifocal sunglasses make it very convenient to perform every day tasks outside without having to switch between your reading glasses and sunglasses. Please note that bifocal sunglasses are intended for people with far sighted vision (good vision for distance or also people that wear regular contact lenses for distance). If you are looking for a pair of outdoor sun readers where the entire lenses are magnified, please look at our Sun Reader Category Here.
