How to buy prescription glasses online?

The first thing to do before purchasing eyeglasses whether online or in-store, is to get a prescription from your eye doctor, optometrist or ophthalmologist. Once your doctor has determined the proper diopter strength and pupillary distance for your prescription, you can head online to your favorite store and choose a frame style based on your taste and preference. DIFF Eyewear offers you the option to order any eyeglass frames and customize them with your prescribed diopter Rx strength.
