Rather than having to constantly switch out glasses based on whether or not you're trying to read, bifocals contain split lenses that allow for distance viewing and reading that are perfect for outdoor use. We are offering 2 pairs of bifocal sport sunglasses, one pair of smoke lens and one pair of yellow lens for driving at night time or a combination of your choice . Wear these sun readers outdoors while reading, driving, or playing sports! Bifocal Sun Readers has a sporty lightweight frame with rubberized nose and ear-pieces. The semi-rimless lenses have a magnified bifocal portion at the bottom, while the rest of the tinted/yellow lens has no magnification. These bifocal sunglasses are great for driving during day or night, the beach and many more outdoor activities. Yellow Lens are helpful in low-light conditions because they make an environment appear brighter. They also are great for contrast and depth perception and are great for overcast, hazy and foggy conditions. These lens tints block blue light, which helps with night clarity. Get a classic and comfortable look while wearing our sport bifocal sunglasses! A microfiber soft pouch is included for storage and protection against scratches as well as for cleaning the lenses.
