Used it to figure out the diopter of reading glasses

Wanted to figure out the diopter values that rubbed off of reading glasses. Worked great.

Producing five parallel, bright and sharply defined light beams this device will turn optical ray diagrams found in science and physics books into visual reality. Demonstrations can be set up in less than five minutes to amaze and illustrate to students and lay audiences alike.
