HOW DO PROGRESSIVE LENSES WORK?
Progressive lenses give 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 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.
