Features: Binocular stereoscopic vision is depth perception generated by binocular parallax and is one of the basic functions of human vision. It is closely related to people's daily life and work. With the rapid development of science and technology, many professions and occupations, such as pilots, drivers of various motor vehicles (ships), athletes, operators of precision machinery, the manufacturing of precision instruments and meters, microsurgery, remote sensing, and remote measurement professionals, all require excellent stereoscopic vision function. This is because it directly affects work efficiency and quality, personal safety, and military combat effectiveness. Therefore, stereoscopic vision tests should be conducted when selecting professionals in the aforementioned fields. The stereoscopic vision test consists of five parts. The first part is a single line stereoscopic vision test chart, which can be used for stereoscopic vision testing or preliminary screening during adult and pediatric physical examinations. The second part is a single stereoscopic vision test chart with different parallax, used as a preliminary screening for stereoscopic vision. The third part is four amblyopia screening charts, used for pediatric amblyopia screening. The fourth part is stereoscopic vision acuity test charts, with a total of 11 charts, with parallax ranging from 30" to 1200". The fifth part is four stereoscopic vision charts with randomly sized dot elements.
