II. Progressive Multifocal Lens:
- What Are Progressive Lenses?
Progressive lenses offer no-line, multi-focal viewing zones for the
most convenient vision correction. If you are over 40 and having
difficulty with your vision, chances are you are experiencing
presbyopia, the common gradual loss of near vision. But there is
good news: you have more choices today than ever before. You don't
have to carry a separate pair of glasses for reading or wear lined
bifocal lenses like your parents did. Now, you can have no line
bifocal reading glasses.
Progressive lenses offer a smooth transition from distance vision
through intermediate vision to near vision, and they supply all the
in-between corrections as well. This means that instead of having
just two different viewing zones (near and distant), like with
bifocals, progressive lenses have progressive powers of correction
(from bottom to top), easing eye strain and providing he most
natural vision correction.
- Progressive lenses offer several vision solutions in one lens
The production of progressives has always been something very
special. Progressive lenses allow smooth, clear vision from near to
far with one lens – and all without image jumps or . Progressive
lenses are therefore a unique feat of optical technology, the
production of which needs a lot of know-how, a vast amount of
optical calculation and exact knowledge of the wearer's personal
parameters. |  |
- Adjusting To Progressive Lenses
If you're new to progressive lenses, you may need a little time to
get used to them. No-line bifocals will slightly alter your
peripheral vision due to power changes that occur at the edges of
the lenses. This initial difference in your peripheral vision will
probably require some slight changes in horizontal head and eye
movements. Sensitivity to this area of the lens will diminish with
time as you become more accustomed to your new lenses.
These guidelines will help you adjust to your progressive lenses
more quickly and comfortably:
Stop wearing your old glasses immediately.
Wear your new glasses non-stop throughout the day.
Wear your new glasses high on the bridge of your nose and as close
to your face as possible.
