The Pupillary Distance (PD) is the distance between the centres of your pupils. With this measurement we can ensure that the optical centres of your lenses are aligned correctly with your pupils to give maximum comfort and effectiveness.
When you have your eyes tested most opticians will not include your Pupillary Distance(PD) measurement on your prescription. Some opticians will gladly give you your PD measurement if you ask for it, while others won’t give you your PD measurement.
At ThinLenses, we have developed a tool that allows you to measure your Pupillary Distance(PD) online. Once you know your Pupillary Distance (PD) you then have the freedom to purchase all your future glasses from anywhere that you want.
