Title:
METHOD AND APPARATUS FOR EYE PROTECTION
Document Type and Number:
Japanese Patent JP2004283564
Kind Code:
A
Abstract:

To provide a method and an apparatus for eye protection against intense diffuse light.

The eye protection apparatus 100 comprises a selectively darkenable element 102 such as a liquid crystal panel and a controller 400 that causes transmission of a darkening signal that causes the selectively darkenable element to darken in conjunction with emission of light, such as intense diffuse light that is used in some medical procedures. Protection against both laser light and diffuse light may be provided in the present eye protection apparatus. The darkening signal is transmitted prior to the emission of the diffuse light, and causes the selectively darkenable element (102) to achieve a darkened state prior to emission of the diffuse light.
