Pupil Distance Measurement Tool

thingiverse

I created this to measure pupil distance. Great tool for education or for getting better measurements when ordering glasses online. It works best when you stare at an object at a distance that your prescription is meant for. For example, if you're getting glasses for distance, look at something far away.Directions: Look through different pairs of holes until the set of circles overlap/align perfectly. If you notice a venn diagram in your peripheral vision, pick a different set.Fun fact: You pupil distance will change depending on how close an object is. When your eyes turn inward to look at a book, they will cross slightly to the point where your pupils will become closer.
