The present invention relates to an eyesight measurement system using a virtual reality (VR) device, and more specifically, to an eyesight measurement system using a VR device, configured to measure eyesight by using the VR device, so that people living in places where a penetration rate of ophthalmologic equipment is low in the past are able to easily examine eye health such as the eyesight, and various parameters for producing glasses are measured together with the eyesight when the eyesight is measured. According to the present invention, the eyesight measurement system using the VR device includes: the VR device equipped with a screen module having a video output function, and a wearing unit for allowing an eyesight measurement target person to wear the VR device on a head； an eyesight test unit installed inside the VR device so as to be movable by a predetermined distance, and measuring the eyesight of the eyesight measurement target person through a refractive examination to generate eyesight information； a mobile terminal mounted in the VR device for transmitting and receiving signals to and from the VR device and the eyesight test unit； an eyesight information calculation unit mounted inside the mobile terminal to receive the eyesight information from the eyesight test unit for storing or processing the eyesight information； a virtual glasses lens generation unit for generating a user-customized virtual glasses lens image based on the eyesight information of the eyesight information calculation unit； and an adjustment image generation unit for overlapping the virtual glasses lens image and pre-stored environmental image information to output an eyesight adjustment effect image according to the virtual glasses lens image to a screen module.본 발명은 VR 기기를 이용한 시력측정시스템에 관한 것으로, 보다 상세하게는 VR 기기를 이용하여 시력을 측정할 수 있도록 구성되어 종래 검안기의 보급률이 낮은 곳에서 거주하는 사람들도 쉽게 시력 등 안구 건강상태를 검사할 수 있도록 하되, 시력을 측정하면서 안경 제작을 위한 다양한 파라미터들을 함께 측정할 수 있는 VR 기기를 이용한 시력측정시스템에 관한 것이다.본 발명에 따른 VR 기기를
