Bifocal sunglasses are a cross between non-corrective sunglasses and reading sunglasses. The top half of the lenses are non-corrective and the bottom half of the lenses are magnified for reading. Bifocal sunglasses are the ideal types of sunglasses for people who need to move quickly from looking at things up close to looking at things far away.
Most bifocals styles come in magnification strengths ranging from 1.25 - 3.00.
