A new high-performance contact lens under development at the department for applied physics at the University of Heidelberg will not only correct ordinary vision defects but will enhance normal night vision as much as five times, making people’s vision sharper than that of cats.
Bille and his team work with an optical instrument called an active mirror -- a device used in astronomical telescopes to spot newly emerging stars and far distant galaxies. Connected to a wave-front sensor that tracks and measures the course of a laser beam into the eye and back, the aluminum mirror detects the deficiencies of the cornea, the transparent protective layer covering the lens of the human eye. The highly precise data from the two instruments -- which, Bille hopes, will one day be found at the opticians (眼镜商) all over the world -- serve as a basis for the production of completely individualized contact lenses that correct and enhance the wearer’s vision.
