The invention provides a synoptophore. The synoptophore is characterized in that the synoptophore comprises a left
optical module, a right
optical module, a lower jaw support and a calculation and control module, wherein the left
optical module can move left and right and can move up and down relative to a position of the lower jaw support; relative positions of the left optical module and the lower jaw support can be adjusted, so that a left
eyepiece can be aligned with the center of a
left eye pupil of a detected person; the right optical module can move left and right and can move up and down relative to the position of the lower jaw support; and relative positions of the right optical module and the lower jaw support can be adjusted, so that a right
eyepiece can be aligned with the center of a right eye
pupil of the detected person. The synoptophore has the beneficial effects that operation is automatic, and use is convenient; examination and training contents are rich, diversified and interesting, so that a child patient is willing to use the synoptophore cooperatively; relative positions of the eyepieces and eyes can be automatically adjusted; in an examination process, an eye watching position of the detected person can be monitored in real time, and rotation of eyeballs can be automatically tracked; and examination and training data can be conveniently recorded and stored.
