What is a bifocal?

A bifocal is a type of eyeglass lens that has two distinct optical powers: one for distance vision and one for near vision. Bifocals are often prescribed to individuals who have presbyopia, a condition that typically develops with age and causes difficulty focusing on close-up objects.

Bifocals can be easily recognized by the visible line that separates the two optical powers on the lens. The upper portion of the lens is used for distance vision, while the lower portion is used for close-up activities such as reading or using a computer.

There are several types of bifocals available, including traditional lined bifocals, blended bifocals (also known as progressive lenses), and occupational bifocals for specific tasks such as computer work or reading music.

Bifocals can be customized to suit individual needs, with various lens materials, coatings, and designs available to enhance comfort and functionality. It is important to consult with an eye care professional to determine the best type of bifocal lens for your specific vision needs.
