Abstract
A device and method, which are utilized in an optical apparatus, for protecting eyes are disclosed. The optical apparatus includes a scanning-mirror component and a visible light source which is optically coupled to the scanning-mirror component. The optical apparatus emits a visible light beam to the scanning-mirror component by using the visible light source. The scanning-mirror component then reflects the visible light beam to emit the visible light beam to a scanning region. The device and the method for protecting eyes can determine at least one eye region in the scanning region, and then make the optical apparatus stop emitting the visible light beam at least within the eye region.
