1.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 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.
2.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 . 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.
3.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:
1.)Stop wearing your old glasses immediately.
2.)Wear your new glasses non-stop throughout the day.
