What Are Progressive Lenses?

Progressive lenses have grown in popularity and are one of the most common solutions to treat vision loss that occurs with age or presbyopia. This eye condition occurs when the eye loses some of its flexibility and ability to adjust to clear seeing objects at different distances. Presbyopia often occurs among adults who are over age 40 and is very easy to correct with a proper and prompt diagnosis.

Progressive lenses are often used to correct this eye condition. Progressive lenses are a modern alternative to bifocal glasses, which provides two prescriptions in a single set of glasses. Bifocal glasses are a better solution than carrying around multiple pairs of glasses. Progressive lenses were developed to resolve some of those common issues and to provide better aesthetics. Progressive lenses provide a smooth transition and can accommodate up to three prescriptions and are a replacement for both bifocals and trifocals.
