WHAT ARE PROGRESSIVE LENSES?
Progressives are far more than just bifocals without lines. In them, the prescription power gradually changes from the top of the lens to the bottom. The top portion is your distance vision correction. As your eyes move down, they will pass through a zone of intermediate power – give or take 2’-4’. This is approximately computer working distance. That being said, if you spend significant time at a computer, you would be much better served with a second pair of glasses, dedicated to that use. The bottom portion of the lens corrects your near vision.
LEARNING TO USE MY NEW PROGRESSIVE LENSES
There are a few tricks you can use in the learning process.
1. Wear your new glasses consistently. Don’t switch back and forth between old and new. Try to keep them from sliding down your nose. This will make it easier to locate all the different zones.
2. Another major assist in finding each area is to point your nose at whatever you are viewing. Then, slightly adjust your head up and down to find the exact correction you need. You will find that the longer you wear your new glasses, less head movement will be needed.
3. When walking stairs or stepping off a curb, take care to look through the intermediate or distance portions of the lenses, as viewing through the near portion will make things appear closer than they are.
In a very short time, you will understand how progressives work for you, and your new lenses will become “second nature."
