Eyeglass Lens Types

Single-vision lenses

Single-vision lenses function as all-purpose glasses for people who do not need a bifocal. People who normally wear bifocals or trifocals can use single-vision for distance or near glasses. Single-vision lenses can also function as occupational glasses for certain types of work. Single-vision lenses can be ordered in all materials.

Aspheric lenses

These new lenses provide special visual and cosmetic benefits for stronger corrections and increase edge-to- edge clarity. Flatter than conventional lenses, aspherics eliminate the "bulgy" appearance of strong plus lenses (far-sighted corrections) and improve the appearance of finished eyewear. Near-sighted people also benefit from thinner, lighter-weight glasses when the lenses are aspheric. Aspheric lenses are positioned closer to the face so there is less eye magnification with farsighted corrections, and less "small eyes" look with nearsighted corrections. Aspheric lenses can be ordered in high index materials for the ultimate in attractive thin lenses.

Flat-top bifocals

This is the most popular form and is available with the bifocal portion made in a variety of widths to aid in various occupations that involve close-up work. Flat-top bifocals can be ordered in every type of lens material.

Franklin-style bifocals

Sometimes used for people who need a wide field of vision for near work (accountants, for example), Franklin-style bifocals have a distinctive look and are usually thicker because of their design. They are generally only available in glass, hard resin, and photochromic glass. They are being replaced by wide Flat-top bifocals.

Trifocals

Trifocals come in a variety of designs. Flat-top trifocals are the most-widely used form. The added segment provides clear vision at arm's length distance, the middle area that is often blurred for bifocal wearers. Trifocals can be ordered in all lens materials.

Progressive no-line bifocals

These modern lenses provide all the benefits of bifocals but add the feature of continuous clear vision at all distances, including mid-range distance (arm's length). People like progressives because they look like single-vision lenses, never revealing the need for bifocals. Progressives are available in all lens materials and are also made in aspheric form. Because of all these advantages, they are becoming the lens of choice for bifocal and trifocal wearers.
