Abstract
An optical system and a head mounted display are disclosed. The optical system comprises: a third lens, a second lens and a first lens glued successively along a propagation direction of incident light. Two glued surfaces of the first lens and the second lens are both Fresnel surfaces. The present disclosure provides a solution of short-focus, high light efficiency, high-resolution, direct transmission optical structure, in which the design of gluing three optical lenses also facilitates reducing stray light.
