Human Eye-Inspired Lens Sees the World More Clearly
• http://www.technewsdaily.com, Staff"The human eye is a GRIN lens," Michael Ponting, a polymer scientist and president of PolymerPlus, said in a statement. "As light passes from the front of the human eye lens to the back, light rays are refracted by varying degrees. It's a very efficient means of controlling the pathway of light without relying on complicated optics, and one that we attempted to mimic."
To create the artificial GRIN lens, Ponting and his team stacked thousands of nanoscale plastic layers, each with slightly different optical properties, to create a lens that can incrementally change the refraction of light.
