The trouble is that most optometrists provide the prescription for you but do not provide the Pupil distance such that the company you are ordering from can get you the exact prescription. This unit allows measure of that distance such that you can provide that information along with your prescription. Because all in my family wear glasses this is a nice item to have around to get the best possible outcome from your glasses.

I used it and got my PD accurately. It’s not too tricky to use. they are less expensive and just as good quality as those bought from the eye doctor.
