Knowing your Pupillary Distance is a requirement when buying glasses. Opthy allows you to determine your PD or verify existing measurements to proceed smoothly with your online purchase. Don’t need glasses right now? No problem – you can still keep track of your PD value for future needs.

No, your PD value is not available directly on your current glasses. If you ever had an eye exam, the value could be found on your prescription, but it is not always provided there.

Opthy operates within a specific range of PD values to give an optimal and personalized experience consistent with the best standards in the industry.

With the current version of the application, Opthy only measures your Far Pupillary Distance. Stay tuned for further developments.

Opthy is intended for single vision lenses within a certain prescription strength range (+/- 5 dioptres). It is not compatible with higher-powered prescriptions, bifocals, progressives or multifocals.
