The computer lens is a multifocal
lens with a comforting reading range of about 16” to
20” inches, computer range from 22” to 26” inches and
progressing to a short distance-range of about 15’ to 20’
feet. There are no segment lines on these lenses, but
unlike the progressive lens these lenses have virtually
no peripheral distortion with a wide corridor
(intermediate lens area), hence perfect for computer
use.
The computer lens is considered an
occupational lens because it is tailored for shorter
ranges and is not intended as an all purpose lens like
its predecessor the
progressive lens. |
