Single vision lenses have the same focal power throughout (top to bottom) and can be used to correct nearsightedness, farsightedness, astigmatism, or a combination of these disorders.

Bifocal lenses have two parts: the upper part normally used for distance vision and the lower part used for near-vision tasks such as reading.

A visible line separates the two fields of vision.

Progressive (no-line bifocal) increases in power from top to bottom. Progressive lenses have no clear dividing lines as the focus changes from bottom to top.

Transition lenses change in color and light transmission when exposed to different light intensities. The rate of darkening depends on the ambient temperature. These lenses do not become as dark when driving because the car's windshield absorbs some of the ultraviolet light that causes the lenses to darken. Transition lenses are available in brown and grey in all lens designs.
