    Abstract: An electronic device such as a head-mounted device may have a transparent member supported by head-mounted support structures. Optical sensors such as time-of-flight sensors and other optical sensors may have light-emitting components and light-detecting components. A stray light blocking structure may be formed in the transparent member. The stray light blocking structure may be configured to block stray light that is traveling laterally through an interior portion of the polymer layer. This prevents the stray light from being received by the light-detecting detecting device. The stray light blocking structure may formed by providing the polymer layer with light redirecting structures such as protrusions and/or recesses. Light-absorbing coatings and/or patterned surfaces such as textured surfaces may be incorporated into the stray light blocking structure.

    Abstract: A head-mounted device can effectively manage heat while also managing noise output levels in a manner that preserves the user's desired experience with the head-mounted device. The head-mounted device can manage sound levels of a cooling system based on detected a sound level of ambient noise in a vicinity of the head-mounted device. For example, the head-mounted device can operate a fan at a speed that produces noise at a sound level that is low enough to be masked by the ambient noise perceived by the user. By further example, the sound level of a cooling system can be based on a sound level of a speaker of the head-mounted device providing audio to the user. By further example, other operational parameters of a cooling system can be controlled to manage noise at a sound level that is sufficiently low.

    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.
