Bifocal Contact Lenses

Many people require different prescriptions for different purposes. Many have to wear different lenses to see a distance and to read. Bifocal lenses provide a solution to those who have multiple vision problems.

Bifocal lenses are designed for people who have a condition called presbyopia. Presbyopia is an eye condition that makes people hold menus, newspapers, and other reading materials further away from the eye to see it clearly. These lenses come in both soft materials and rigid gas permeable materials. Some can be worn on a disposable basis which means the person has the convenience of throwing the lenses out at specific intervals, sometimes even daily. They are then replaced with fresh, new lenses.

Bifocal contacts have two prescriptions in one lens. Multifocal lenses have a range of powers. They are the contact lens equivalent of progressive lenses in glasses. “Multifocal” is also used as something of a catch-all for lenses that have more than one power, including bifocals.

Bifocal lenses work in several ways, depending on the design of the lens. The two main methods are “alternating vision” and “simultaneous.”

Alternating vision lenses are named because the pupil alternates between the two powers, as the person’s gaze shifts upward or downward. Simultaneous vision lenses require the eye to look through distance and near powers at the same time. While this might sound complicated, the visual system will select the correct power choice depending on how close or far away the desired object is.
