A powerful lens technology inspired by the human eye

November 15, 2012

Drawing heavily upon nature for inspiration, a team of researchers has created a new artificial lens made up of thousands of nanoscale polymer layers that is nearly identical to the natural lens of the human eye.

The lens may one day provide more natural performance in implantable lenses to replace damaged or diseased human eye lenses, as well as consumer vision products; it also may lead to superior ground and aerial surveillance technology.

This work, which the Case Western Reserve University, Rose-Hulman Institute of Technology, U.S. Naval Research Laboratory, and PolymerPlus team describes in the Optical Society’s (OSA) open-access journal Optics Express, also provides a new material approach for fabricating synthetic polymer lenses.
