Displays with Adjustable Haze and Tint Layers

Abstract: a pair of glasses or other eyewear may include a display that produces display content and an optical system through which the display content is viewable from an eye box. the optical system may include an optical combiner that combines real-world light with the display content. the glasses may be operable in a transparent mode for viewing the environment and a dark mode for viewing display content on the glasses. the optical system may include a light modulator layer such an adjustable tint and haze layer that both darkens and diffuses ambient light when the glasses are being used to view display content in the dark mode. the optical system may be configured to darken ambient light more than display light from external displays so that the user can use electronic devices while wearing the glasses.
