Abstract
An augmented reality (AR) optical device comprises an AR optical system configured to generate an AR image and lay the AR image over an actual environment image perceived by a user and a light attenuator disposed in a direction along which the AR optical system is optically exposed to an actual environment and configured to attenuate a brightness of the actual environment image.
