Disclosed is a multi-ring multi-focal-length single-ring inner wavy lens. The lens comprises a main lens area and a concentric circular ring area. The concentric circular ring area comprises a plurality of circular rings, the plurality of circular rings are concentrically distributed with the center of the lens as the center, the width of an annulus between every two adjacent circular rings gradually increases from inside to outside, and the circular rings each are of a wavy structure. Each wavy structure comprises peaks and valleys, the diopter of a position where each peak is located is greater than that of the main lens area, and the diopter of a position where each valley is located is smaller than that of the main lens area. The lens disclosed by the present disclosure can provide a plurality of focus regions to enhance the fitness of human eyes.

A method, performed by an augmented reality (AR) device including a vision correction lens, of detecting a gaze of a user is provided. The method includes obtaining lens characteristic information about the vision correction lens arranged to overlap a light guide plate in a gaze direction of the user, emitting light for gaze tracking toward a light reflector through a light emitter, wherein the emitted light is reflected by the light reflector and then directed to an eye of the user, receiving a light reflected by the eye of the user through a light receiver, obtaining an eye image of the user based on the light received, adjusting the eye image of the user based on the lens characteristic information about the vision correction lens, and obtaining gaze information based on the adjusted eye image.

A spectacle ophthalmic lens mountable on a spectacle frame, the ophthalmic lens including: a fitting cross where the optical power is negative; a first zone extending in a temporal side of the fitting cross, wherein in the first zone when the ophthalmic lens is mounted on the spectacle frame, the optical power increases when a gazing direction moves towards the temporal side, and wherein over a nasal side of the fitting cross, the optical power of the ophthalmic lens is substantially same as at the fitting cross.

A technology concerning a pair of spectacle lenses for binocular vision. In each of the pair of spectacle lenses for binocular vision, when an inner horizontal direction of each of the spectacle lenses is a direction toward the nose of a user who wears the spectacle lenses, and an outer horizontal direction of the spectacle lenses is a direction toward an ear of the user, a portion for viewing an object at finite distance is provided in each of the pair of spectacle lenses for binocular vision and a shape of a base in prism is formed in the position such that a line of sight of a user viewing an object through the portion is directed to a direction that is different from a direction from the object.
