Optical lens group for augmented reality display and virtual imaging device using same, and near-eye display

An optical lens group for augmented reality (AR) near-eye display, comprising a primary lens and an auxiliary lens, the auxiliary lens being adjacent to at least one surface of the primary lens, wherein

• the primary lens comprises a first optical surface configured to receive image light that is subject to at least one total reflection, and one reflection depending on a transmission-reflection split ratio in the primary lens after entering the primary lens through the first optical surface, and then is transmitted out of the primary lens and reaches an exit pupil position, a tilt angle θ of a normal line at a vertex position of an optical surface of the primary lens facing the exit pupil position with respect to a normal line of an exit pupil plane satisfies 0°<θ<10°, and a field of view of the image light received by the lens group with respect to a user eye at the exit pupil position is determined solely by the primary lens;
• the auxiliary lens is disposed at least adjacent to an optical surface of the primary lens distal from the first optical surface;
• and
• a surface of the auxiliary lens facing an environment side extends from a surface of the primary lens distal from the first optical surface to be in continuity with a second optical surface of the primary lens, or extends from a surface of the primary lens distal from the first optical surface to a direction of a second optical surface of the primary lens to partially cover the second optical surface.
