Vision detection apparatus and method

Abstract

A vision detection apparatus is provided which comprises an eye lens, and the followings which are juxtaposed, with the eye lens as a common component: an ocular axial length measurement light path for measuring an ocular axial length of a detected eye; a diopter detection light path for obtaining refractive error information of the tested eye; an optotype light path for providing a fixation image for the detected eye 1 and enabling the detected eye to gaze stably; an eye position monitoring light path for performing three-dimensional positioning for the detected eye and collect imaging information of the detected eye. Through the present disclosure, it is possible to obtain information on refractive errors in the eyes, measure the anterior and posterior segment regions, and obtain eye parameters such as axial length, which has high practical value in vision detection of the teenagers.
