April 7, 2006— New eyeglasses that shift focus from distant to near objects could soon replace bifocals and correct other vision problems.
The so-called switchable electro-optic diffractive lenses were reported in the Proceedings of the National Academy of Sciences by researchers at the University of Arizona in Tucson andf the Georgia Institute of Technology.

This is another example of things I have thought about that are invented almost as quick as you think of them. Could these self focusing glasses take on other roles. Binoculars for example or magnifying glasses. These would be neat if they work.
