Abstract

The present invention relates to an eyepiece optical system and a head-mounted display device. The system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens arranged coaxially and sequentially in an optical axis direction from an observation side of human eyes to a micro-image display, and meeting a certain focal length relationship. The first lens, the third lens, and the fourth lens are positive lenses, the second lens and the fifth lens are negative lenses, and material properties of various lenses meet a certain relationship, which effectively alleviates defects of the prior art, and has a better aberration correction ability and better processability, thereby achieving performance indicators such as large field-of-view angle, low distortion, and high optical resolution, reducing the manufacturing difficulty. The eyepiece optical system of the present invention is suitable for head-mounted displays and similar devices.
