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.

SF 14 / 17mm Corridor Progressive Multifocal Lenses , 1.499 UC Resin Lens Blanks

1) 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.

2) Wear your glasses high on your nose, and close to your eyes to maximize the range of visibility through each lens.

3) 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.

4) 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.
