Description

Single Vision Are designed to help people who require correction of farsightedness, nearsightedness, or astigmatism. These eyeglasses have just a single optical prescription correction and they distribute focus evenly over the entire surface area of the lens. Most people that wear glasses usually get this type.
Bifocal Bifocal means “two focuses”. Bifocal lenses contain two different prescriptions: an upper section to allow for distance vision and an additional power on the bottom part of the lens to aid in close up focus.

Trifocal Glasses Like bifocals, the top section is for distance vision and the bottom is reserved for reading and other close tasks. The middle, however, is for intermediate vision, that lands somewhere between the two.
Progressive Multifocal Lenses A progressive lens gradually changes power from the top of the lens to the bottom, giving a smooth transition from distance vision to intermediate/computer vision to near/reading vision.
