Abstract
The present disclosure provides an optical system and a near-eye display device. The optical system includes an optical waveguide and an eyepiece system. The eyepiece system is on a light incident side of the optical waveguide, and a light exit side of the eyepiece system is opposite to the light incident side of the optical waveguide so that light exited from the eyepiece system is incident on the optical waveguide. The eyepiece system includes a lens group which includes a first lens, a second lens and a third lens which are sequentially arranged in a direction parallel to the optical axis of the lens group; a side of the first lens away from the second lens is the light exit side of the eyepiece system, each of the first lens and the third lens has a positive focal power; and the second lens has a negative focal power.
