KNOW THE DIFFERENCE
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 area that is usually blurred for bifocal wearers. Trifocals are available in all lens materials.
Progressives (no line bifocals)
These 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). Progressives have the cosmetic advantage of appearing to be single vision lenses so they never reveal the user wears bifocals. Progressives are available in all lens materials and are also made in aspheric form. Because of their many benefits, they are becoming the lens of choice for bifocal and trifocal wearers. New technology in progressive lenses, also referred to as “digital” progressives, has made progressive lenses the most advanced lenses on the market today. See more about digital lenses below.
These 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 for far-sighted corrections and greatly enhance the appearance of finished eyewear. Persons 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, wearers experience less of the “small eyes” appearance caused by nearsighted corrections. Aspheric lenses are often made of high index materials for the ultimate in thin lenses.
Single Vision Lenses
Single vision lenses use the same optical focal point or correction over the entire area of the lens. Single vision can be used to correct various eyesight issues and is the most common type of lens.
