Progressive lenses, also known as varifocal lenses, are a type of lens that provides vision correction for both far, near and intermediate distances. Where a normal bifocal or trifocal lense would require a segment line where the near and far prescriptions meet, a progressive spectacle lens provides a smooth transistion between prescriptions.
Who Are Progressive Lenses For?
The progresive lens is most popular for people with presbyopia, a condition that progressively affects near-vision with age. It is also a good fit for those who need correction for distance and reading but do not want a lined bifocal or trifocal lens.
Key Benefits of Progressive Lenses
The progressive lens also provides a measure of intermediate vision correction that allows for "in-between" distances such as computer, grocery shelf or your car instrument panel that is not possible with non-progressive lenses.
Note: Progressive lenses should not be confused with Transition Lenses, which are lenses which quickly adapt to changes in ambient light strength to prevent eye damage from sun rays.
