This invention provides a myopia screening device. The first end of the housing is designated as the detection end for testing the subject's eyes. A visual target screen, a screening camera, and an optical path assembly are all housed within the housing. The visual target screen is located on one side wall of the housing, the optical path assembly is positioned between the detection end and the visual target screen, and the screening camera is located at the second end of the housing. The screening camera captures a light and shadow image of the subject's pupil. A processor processes and analyzes the light and shadow image captured by the screening camera. An input device communicates with the processor and inputs the image seen by the subject on the visual target screen into the processor. This invention enables not only refractive error testing but also visual acuity testing and color blindness / color weakness testing. Furthermore, this invention can estimate the subject's visual acuity based on the refractive error test results, generate a corresponding estimated visual target based on the estimated visual acuity, and quickly complete the visual acuity test, effectively shortening the visual acuity screening time.

The application discloses a display improvement method and system based on full color blindness, a terminal and a storage medium. The method comprises the following steps: acquiring brightness information of each partition image, and obtaining a first image brightness matrix based on the brightness information; acquiring the maximum brightness and the minimum brightness of the first image brightness matrix, and calculating the difference between the maximum brightness and the minimum brightness; converting the first image brightness matrix based on the difference to obtain a second image brightness matrix, and transmitting the second image brightness matrix to a display to complete image display. The application is based on the visual characteristics of the full color blindness population, and through a segmented brightness conversion function, an image more suitable for the full color blindness population is obtained, a personalized viewing mode is provided for the full color blindness special users, a more comfortable viewing experience is brought, and the happiness index of the full color blindness special users is improved.

The invention provides a color blindness detection method and head-mounted equipment. The color blindness detection method comprises the following steps: selecting and calibrating target head-mounted equipment; creating a color blindness detection image set and a display mode corresponding to the detection image set in the target head-mounted device; displaying the detection image set according to the display mode through the target head-mounted device, and guiding a to-be-detected user to answer questions according to display contents; and obtaining a detection result according to an answer result corresponding to the detection image set, and determining color blindness parameters of the to-be-detected user according to the detection results of all the detection image sets. According to the invention, automatic detection of color blindness can be rapidly realized, the consistency of detection for different users is high, and misjudgment is reduced.
