So, first thing’s first: what is pupillary distance (PD)? Essentially, it’s the distance between the centres of your pupils (the black bits in the middle of the eyes).
Your PD is an important part of your glasses prescription that makes sure you’re looking through the best spot in your lenses for clear vision. We’ll need this measurement if you’re buying your specs online.

Once that’s all done, you’ll be able to pick out your next pair of frames and add all your prescription details – all from the comfort of your sofa.
