Catadioptric lens assembly having two or more lens components

An optical lens assembly for displaying an image emitted by a display to a viewer along an optical axis, the optical lens assembly comprising:

• a middle-lens disposed between, and bonded to, an eye-lens and a display-lens, each of the lenses comprising an active lens region defined as a maximum lens region configured to transmit the image emitted by the display therethrough along the optical axis, such that at least across the corresponding active lens regions:
• the eye-lens comprises opposing curved first and second major surfaces, a maximum thickness tmax1 and a minimum thickness tmin1, tmin1 less than tmax1 by less than about 30%;
• the middle-lens comprises a curved first major surface bonded to the second major surface of the eye-lens, an opposing second major surface, a maximum thickness tmax2, and a minimum thickness tmin2 less than tmax2 by greater than about 30%, tmax2 greater than tmax1 by at least 30%;
• and
• the display-lens comprises a first major surface facing the second major surface of the middle-lens and an opposing curved second major surface;
• wherein the active lens regions of the middle-lens and the display-lens define a space between the second major surface of the middle-lens and the first major surface of the display-lens, one or more optical elements filling the space and bonding the middle-lens and the display-lens to each other, wherein in the space, a minimum gap between the second major surface of the middle-lens and the first major surface of the display-lens is Gmin, and a maximum gap between the second major surface of the middle-lens and the first major surface of the display-lens is Gmax, Gmax−Gmin≥20 microns.
