Electrically controlling transparency
In Europe and America, people often wear sunglasses to protect their eyes.
They use them in a variety of daily environments — driving a car, enjoying sport activities, and more.
An adjustable lens shade can maximize the comfort of using sunglasses. Preferences vary with individuals, and requirements vary with applications.
Ricoh has developed an electrochromic material for use in sunglasses whose shades can be electrically adjusted between transparency and tints.
Ricoh will expand applications of the technology, exploiting its strengths:
*This technology has been developed partly under subsidy from the New Energy and Industrial Technology Development Organization (NEDO), a national research and development organization.
