On a late night in February 2011, two Princeton University researchers packed a small object into a box and set it out for the morning mail. The engineers had spent four years developing a new type of ...

Researchers have developed a low-cost, easy way to make custom lenses that could help manufacturers avoid the expensive molds required for optical manufacturing. Researchers from Washington State ...

Researchers have designed an equilibrium model to demonstrate the elastic stresses and suction pressure distribution between a soft hydrogel contact lens and an eye. The model allows arbitrary ...
