Abstract
The invention discloses a hood type dominant eye measuring apparatus, which comprises a hood (1), a connecting rod (2) and a main eye plate (4). One end of the connecting rod (2) is fixedly arranged in the front middle of the edge of the hood (1), the other end of the connecting rod (2) is slidably connected with the main eye plate (4) after penetrating through a slide hole (7) at the vertical center line of the upper portion of the main eye plate (4), and the main eye plate (4) is provided with an inspection hole (8) below the slide hole (7). By the aid of the connecting rod which is provided with scales, arranged on the front side of the hood and connected with the main eye plate slidably, specific position of the dominant eye of the person to be measured can be determined individually, measurements of dominant eyes of different distances can be realized on the condition that measurement distance and direction are determined, so that error in measurements is avoided, and simultaneously standardization of measurement programs and devices is realized. Further, the hood type dominant eye measuring apparatus has the advantages of simple structure, convenience in operation, small size, light weight, stabile gravity center, wearing adaptability, measurement accuracy and wide adaptability to head forms of different users, and is suitable for popularization.
Description
technical field [0001] The present invention relates to the field of ophthalmic and optical instruments, in particular to the field of instruments for measuring human binocular vision function, in particular to a headgear-type dominant eye measuring device for determining the parameters of the dominant eye during ophthalmic clinical examination and optometry. . Background technique [0002] Dominant eye, also known as dominant eye, beneficial eye, and dominant eye, refers to the eye that has the dominant power in the visual function of both eyes is the dominant eye. The dominant eye is divided into right dominant eye, left dominant eye, alternate dominant eye, middle dominant eye and so on. The so-called alternating dominant eye is the alternating exchange of the dominant eye, sometimes the right eye is the dominant eye, sometimes the left eye is the dominant eye; However, the general rule is: the right eye is dominant, followed by the left eye, and there are very few peo...
