7 Of The Best Places To Buy Glasses Online For Cheap

If you wear glasses, you know first-hand just how frustrating it can be to buy a new pair of frames. Chances are your doctor’s office has a slim selection of styles, and what they do have is overpriced and not always in style.

Before you purchase new glasses online, you’ll need a copy of your most recent glasses prescription. (And no, your contact prescription won’t work for new glasses, sorry).

You’ll also want to learn how to measure your PD, or pupillary distance. It’s the distance in millimeters between the center of one pupil to the center of the other. This measurement ensures that you’re looking through the ideal spot in your lenses.

Lastly, just remember to check with your insurance provider first in order to know what type of frames, lenses, and costs are covered by your health insurance plan.

If you’re in the market for a new pair of frames, but don’t want to lighten your wallet, we’ve pulled together a list of reliable easy-to-use sites to buy glasses. We’ve also got a guide to the best places to buy contacts online for cheap, in case you’ve retired your old frames.
