Deep-focus glasses, xr glasses and contact lens with collimation function

XR glasses, comprising:

• a transparent left-eye housing and a transparent right-eye housing that are integral with a frame,
• a transparent column assembly that is movably housed in the left-eye housing and the right-eye housing, respectively,
• at least one eye tracking sensor that is attached to each of the left-eye housing and the right-eye housing;
• and
• an opaque or semi-transparent left-eye display and an opaque or semi-transparent right-eye display that are provided on a front surface of the left-eye housing and the right-eye housing, respectively,
• the transparent column assembly being configured such that a plurality of transparent columns serving as collimators are arranged, the transparent columns having a radiation angle of 5 degrees or less for 50% or more of transmitted light with respect to incident light, and the light transmitted through each transparent column is converged to a convergence point,
• the XR glasses having the function of moving the transparent column assembly inside the left-eye housing and the right-eye housing so that it faces the pupil and the convergence point is located on the surface or inside of the cornea, inside the pupil, on the surface or inside of the crystalline lens, or inside the eyeball, depending on the result of detection of the position of the pupil of the user's eye by the eye tracking sensor.
