HEAD-MOUNTED DISPLAY DEVICE WITH VISION CORRECTION

A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relativeto the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when theuser's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors. 一种头戴式显示器可包括外壳中的显示系统和光学系统。该显示系统可具有产生图像的显示器。定位器可用于相对于用户的眼睛的眼睛位置来移动该显示器。可调节光学系统可包括可调透镜，诸如可调柱面液晶透镜。当用户的眼睛位于眼睛位置时，可通过透镜观看显示器。
