Vision test
Vision examination is one of the important methods of ophthalmic clinical examination. It is a test conducted by ophthalmologists, optometrists, and vision correction specialists to assess the subject's visual ability and level, their ability to track focal points, and their ability to distinguish objects, in order to determine whether the patient has myopia or hyperopia, as well as astigmatism, and the degree and axis of astigmatism. Vision examination can be used for preliminary assessment of the function of the retina, optic nerve, and macula. Reliable vision examination is of great significance for the diagnosis and treatment of ophthalmic diseases and the evaluation of prognosis. It also has important value in children's vision screening and myopia prevention and control in adolescents.
