PD (Pupillary distance) is required for each prescription for accuracy. Kindly note that our virtual try on accurately measures your PD automatically with advanced technology. If the virtual try on button is unavailable please use the following Opthy app to measure your PD.
You can select the default settings of 61 for women and 64 for men if you have an average or low prescription. If you have a strong prescription (or if you want to know your exact PD), please measure your PD to complete your prescription. Download the Opthy app to get an accurate PD or use our Virtual Try on.
