Single Vision Lenses
Single vision lenses function as all-purpose glasses. People who normally wear bifocals or trifocals can use single vision for distance or near lenses. Single vision lenses can also function as occupational glasses for certain types of work. Single vision lenses are available in all lens materials.
 
Aspheric Lenses
These new lenses provide special visual and cosmetic benefits for stronger corrections. Aspheric lenses eliminate the bulgy appearance of strong lenses for farsighted corrections and greatly enhance the appearance of finished eyewear. People with strong nearsighted corrections also benefit from thinner, lighter-weight glasses when their lenses are aspheric. Because aspheric lenses are positioned closer to the face, there is less eye magnification with farsighted corrections and less of a “small eyes” look with nearsighted corrections. Aspheric lenses are often made of high-index materials for the ultimate in thin lenses.
 

Flat Top Bifocals
This is the most popular bifocal form, and is available with the bifocal portion made in a variety of widths to help with various occupations that require close-up vision. Flat top bifocals are available in all lens materials.
 
Trifocals
Trifocals come in a variety of designs. Flat top trifocals are the most widely used form. The added segment provides clear vision at an arm's-length distance, the area that is usually blurred for bifocal wearers. Trifocals are available in all lens materials.
 
Progressives
Progressive, or no-line bifocals, provide all the benefits of bifocals but add the feature of continuous clear vision at all distances, including mid-range distance (arm's length). Progressives have the cosmetic advantage of appearing to be single vision lenses, so they never reveal that the user wears bifocals. Progressives are available in all lens materials, and in aspheric form. Because of their many benefits, they are becoming the lens of choice for bifocal and trifocal wearers.
