Multifocal Lenses
Multifocals help you to focus at different distances through the same lens and generally have three points of focus:
-
Distance – such as driving a vehicle or watching television
-
Intermediate – such as working on computer
-
Near – such as reading or other
close-up work
A small portion at the bottom of the lens is reserved for your near-vision correction, a small portion at the top is for distance correction, and the zone in between is designed to allow your eye to move smoothly between distance and near.
It may take 2 to 3 weeks for your eyes to get used to your new multifocals. And with time you’ll notice that your eyes naturally seek out the appropriate portion of the lens. You may also find that the very sides of the lenses show some distortion. This is normal and unavoidable with this type of complex lens. After a short time your eyes will become accustomed to this and you will no longer notice it.
