**bifocals**

Bifocals are eyeglasses with lenses that have two distinct optical powers, designed to help people who need correction for both near and distance vision. The upper part of the lens typically corrects distance vision, while the lower part is for reading or close-up tasks. They are commonly prescribed for individuals with presbyopia, a condition that affects the eye’s ability to focus on nearby objects as people age. Bifocals improve visual comfort and reduce the need to switch between multiple pairs of glasses.
