What Are Bifocal Glasses?

Bifocal lenses are divided into two parts to accommodate two different prescriptions in one lens. One area of the lens will have one prescription (usually distance) and a segment in the lower half will have the other (usually near vision).

Bifocal glasses are most used to correct presbyopia - an age-related eye condition where the eyes begin to struggle to focus on anything up close. This difficulty usually results in people requiring glasses with two different prescriptions, one for short and one for long-distance.

On bifocal glasses, there is a distinct line between the different prescriptions. Wearers have to look up and down to switch between the prescriptions they need, with long-distance prescriptions at the top and near vision at the bottom.
