Abstract: A method of active-dimming control for augmented-reality glasses. The method includes, while a user is wearing augmented-reality glasses, obtaining a first set of light information measured via a first sensor on the augmented reality glasses which is positioned to receive light after it travels through a dimmable element of the augmented-reality glasses. The method further includes obtaining a second set of light information measured via a second sensor on the augmented reality glasses positioned to receive light that has not travelled through the dimmable element of the augmented-reality glasses. The method further includes electronically adjusting a dimming level of the dimmable element based on a comparison between the first set and second set of light information.
