Problems solved by technology

[0004] Therefore, it is particularly important to obtain the refractive parameters of the eyes, and the existing equipment for detecting the refractive state of the eyes, such as autorefractors and aberrometers, are bulky, heavy, and expensive, and often require professional optometrists to participate in the measurement , which makes the detection cost high and is not conducive to popularization and use

Abstract

The invention discloses eye optical parameter detection equipment and a head-mounted display. The detection equipment comprises a light beam generating device, an optical imaging device and a processer, wherein the light beam generating device is used for generating at least two measurement light beams pointing to eyes to be detected, the measurement light beams or the oppositely-elongated lines of the measurement light beams intersect on at least one virtual light source point, the optical imaging device is used for performing imaging on light spots formed on the retinas of the eyes to be detected of the at least two measurement light beams so as to obtain a light spot image, and the processer is used for analyzing the light spot image so as to obtain optical parameters of the eyes to be detected. Accordingly, the eye optical parameter detection equipment can conveniently obtain the optical parameters of the eyes to be detected.

Description

technical field [0001] The present invention relates to a detection device, and more specifically, to an eye optical parameter detection device and a head-mounted display capable of detecting the optical parameters of the eye. Background technique [0002] Human eyes have a certain adjustment ability, and the adjustment ability of the eyes of different individuals is different. The adjustment ability mentioned here refers to the ability of the eye to use the position and shape changes of the lens and other structures to change the refractive power of the eye's optical system, so that objects at different distances can be clearly imaged on the retina. [0003] Generally speaking, the adjustment ability of the eyes can be expressed in diopters. The state of refraction when the eye does not use adjustment is called static refraction. The power of static refraction of the standard eye is +58.64D. The state of refraction of the human eye when it is adjusted is called dynamic ref...
