Unlike in-store shopping, you do not have the opportunity to try on different frames and make adjustments on the spot when shopping for eyeglasses online. Here are some benefits of accurate PD measurement for online glasses shopping:
Proper fit  for visual clarity: When your lenses are aligned with your pupils, you are looking through the most optimal part of the lenses for clear vision. Accurate PD measurement ensures that you are receiving the correct prescription and experiencing optimal visual clarity.
Convenience: Ordering eyeglasses online offers convenience and saves time. Thus, you can confidently order your glasses from the comfort of your own home without the need for in-person adjustments.
Cost savings: Ordering glasses online often comes with cost savings compared to traditional brick-and-mortar stores. With an accurate PD, you can avoid the need for costly adjustments or returns due to ill-fitting glasses.
