and near viewing areas in one
single pair of glasses.Available as
no-line progressives,
bifocals and trifocals.
No-Line Progressivesdesigned to
allow you to see atdistance (driving a
vehicle), intermediate (looking at the dash board), and
near (reading a map) with no lines or
sections.The absence of bifocal
lines makes this lens themost desirable cosmetically.You will also enjoy continuousvision from far to near
with this lens design.
Bifocals
provide both far and near correction in one lens. A visible line
divides the two areas providing a visiblesegment for near
viewing.
Trifocals
are a variation of the bifocals.
This double-line
lens provides you with correction in three areas - distance,
intermediate, and near.
Asphericsreduce the
effect of your eyes looking larger or smaller behind your
glasses.Plus, the image remainsmore clear when you look through the sides of the lenses,
and the lenses are thinner and lighter.
