What Are Trifocal Lenses?
In an effort to correct the problem of lacking an intermediate viewing area, trifocal lenses were invented. Trifocal lenses offer correction for near and far vision, but also enable a person to see clearly at an intermediate level (about the length of your arm). Trifocals help correct the intermediate zone by featuring a second small lens segment directly above the area used to correct near vision. This results in a total of three power zones, thus the name trifocal. This intermediate segment allows the wearer to better see things like the computer screen or the car instrument panel on the dashboard. Just like bifocal lenses, trifocal lenses also contain visible lines on the lenses.
