Abstract
Method of recovering vision by using a pair of glasses, comprising: dividing a diopter range into multiple diopter intervals with continuous diopter variation; selecting a first diopter interval and a second diopter interval from the multiple diopter intervals according to a user's vision recovery requirement which is lower than the user's actual diopter; selecting a left lens group corresponding to the first diopter interval and a right lens group corresponding to the second diopter interval of the glasses, which both the left lens group and the right lens group include a movable lens and a stationary lens; continuously adjusting the diopter of the glasses to be lower than the user's actual diopter, so that the adjusted diopter of each lens group satisfy the user's vision recovery requirement.
