Abstract
An electronic device such as a head-mounted device may have a head-mounted housing that separates an exterior region from an interior region. Optical modules may be mounted in alignment with openings in the rear of the housing. Each optical module may have a display and a lens through which an image on the display may be viewed. To protect the optical modules, the head-mounted device may be provided with photochromic lenses that darken and block sunlight when exposed to ultraviolet light and/or may be provided with shutters, lens caps, protective movable housing portions, tunable lenses that can be adjusted to defocus sunlight, and/or other protective structures for protecting lenses from scratches and for protecting displays from damage due to excessive sunlight exposure. Electrically adjustable protective structures may be operated based on sensor measurements.
