Abstract
The utility model discloses a left, right eye identification device of an ophthalmology department instrument, belonging to the technical field of the optical instrument, which solves the left, right eye accurate identification problem when the optical instrument performs the eye examination. The left, right eye identification device comprises an optical instrument main body, an optical instrument base or a desk top, a left feature part, a right feature part, a light emitter, a light receiving device, a signal process unit and a power supply. The light emitter is connected with the optical instrument and moves left or right relative to the optical instrument base or the desk top, the light from the light emitter is irradiated on the left feature part or the right feature part with different colors, heights, reflectivities or light transmission rates, and reflected or transmitted by the left feature part or the right feature part and then the light is irradiated on the light receiving device, the signal of the light receiving device is processed by the signal process unit and output to identify whether the optical instrument moves to the left eye of the patient or the right eye. The left, right eye identification device is mainly used for being mounted and used on the ophthalmology department instrument capable of moving left or right.
