Buying glasses online may seem intimidating at first, but is actually as easy as shopping for most products online. All you need is a little guidance. Here are 6 easy steps to make your shopping experience a breeze:
You'll need a non-expired prescription to order new prescription glasses. Most prescriptions will last 1-2 years.
The pupillary distance is the measurement between the center of the pupil of both eyes, and is crucial in making sure the lenses are centered correctly. Otherwise you may experience eye strain or other negative effects. If the PD is not on your prescription, you can either ask an eye care provider for the measurement or use an online tool for measuring the PD.
Choosing the right lens type will affect vision, appearance, comfort, and safety. Single vision lenses will correct the farsightedness, nearsightedness, and/or astigmatism. Bifocal or progressive lenses will also correct presbyopia, which should be indicated in your prescription. The most common lens materials include CR-39, Polycarbonate, Trivex, and High Index Plastics.
