II. Progressive Lens:
Progressive lenses have three prescriptions in one pair of glasses. That allows you to do close-up work (like reading a book), middle-distance work (like checking out a website on a computer), or distance viewing (like driving) without needing to change your glasses. They're sometimes called multifocal lenses.
Progressive lenses are an update on bifocal and trifocal lenses. Both of these more traditional types of glasses have telltale lines in the lenses. Progressives have a seamless look. Sometimes they're called "no-line bifocals," but that's not quite right. It would be more accurate to call progressive lenses "no-line trifocals."
A progressive lens gives you three vision powers in one seamless lens for a more natural and flattering way to see your world. If you need more than one lens strength to read, do computer work or drive, progressives let you can see clearly at any distance with one pair of glasses. You simply adjust your head position to see three ranges of distance. Bring your head up to see far away; look straight ahead for mid-range vision, and point your nose down to read or do close-up work, like texting.
Like anything new, adjusting to progressives can be frustrating, but don’t worry. Here are a few tips that’ll have you seeing clearly all the time, at every distance, with one pair of glasses.
|
---Resist the temptation to switch back and forth to your old glasses—this slows down the process of retraining your brain to focus through new lenses.
---Wear your glasses high on your nose, and close to your eyes to maximize the range of visibility through each lens.
---Move your head, not your eyes. Point your nose directly at what you’d like to see and bring it into focus by moving your chin up or down.
---Practice! Grab a magazine to read while watching TV. Going back and forth between the two is a great way to practice and to speed up your transition.
