PD Measurement Tool
Measure your PD online
In most cases, your optician will include your PD measurement in your prescription after the eye examination. If not, just ask for it.
At Yesglasses, we have developed an easy and free online tool that measures your PD, with which you are able to buy all your future glasses online.
Please read How to Measure PD if you want to measure your PD manually at home.

Natural light or bright environment also improves accuracy.
