I have seen used eye glasses donation stations here and there but what are the chances that my prescription will match up exactly to what someone in a third world without having 500 people try them on. These Eyejusters are Self Adjusting Eye Glasses so they solve that problem by making one size fit all. Well not exactly, there are actually two types of adjustable lenses that are needed to fit all prescriptions. The one great thing about these lenses is that you never need to change them if your eyes change, just adjust them on the spot! Why wasn’t this invented long ago?

Thanks for the tip Bob.
