LENS MATERIALS

Glass glass lenses are the oldest and heaviest material - Very limited color selection - usually just clear and photo chromatic. Glass lenses are very seldom used today and can be the most expensive type to use.

Plastic plastic lenses are lighter than glass lenses, and can be tinted to almost any color and shade. The most popular material used today - especially when combined with a scratch resistant and UV protecting coating.

Thinner, lighter high-index technologically advanced high-index lenses create a thinner profile for those with strong prescriptions. These lenses are more comfortable as well as cosmetically desirable, about a third thinner and lighter than plastic lenses.

LENS DESIGNS

Single Vision this all-purpose lens is available in all materials, and can be used for either distance or near vision correction.

Multifocals will be suggested when both distance and near correction are needed together in a single lens.

No-line progressives correct for far (driving a vehicle), intermediate (viewing the dashboard), and near (reading a map) vision all in one lens. Because there is no visible line, progressives have the appearance of single-vision lenses and are, therefore, the most cosmetically desirable multifocal. Progressives are available in all lens materials.

Bifocals provide both far (driving) and near (reading a map) correction in one lens.

Trifocals . Three segmented lens The majority of the lens is for distance viewing, while the center portion is divided into intermediate and the bottom area for near viewing.
