PD Self Test – calculate your own pupil distance and save an optician’s visit…


This PD Self Test service is a free method of calculating the exact distance between your pupils. It’s used for measuring the width of eye glasses accurately so you get to see correctly through the lens. With the rise of online eyeglasses retailers, this sort of thing is very useful indeed. You can either upload a full face image from your computer, or use a webcam to take a snap, then grab the results by following the instructions.

Nigel is the managing editor of the Red Ferret, as well as a freelance columnist for the Sunday Times newspaper in London. Loves tech and fancies himself as a bit of a futurist, but then don’t we all?
