Abstract
A method and device for refraction adjustment in an augmented reality apparatus, and an augmented reality apparatus. The method for refraction adjustment includes: receiving light rays reflected from eyes of a user wearing an augmented reality apparatus; determining a pupil distance of the user according to the reflected light rays; and generating a refraction correction signal according to the pupil distance of the user and a desired diopter(s) for correcting diopters of the user's eyes by means of a refraction adjustment element.
