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.
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.
