Bifocal lenses are designed to help people with both near and distance vision problems. These lenses have two distinct optical powers: the upper part is for distance vision, while the lower part is for near vision, such as reading or using a smartphone. The transition between the two areas is usually marked by a visible line on the lens. Bifocal lenses are ideal for those who need help with both reading and seeing objects at a distance, offering a convenient solution in a single pair of glasses.
