Abstract
A retinal scanning type eye examination device includes a storage unit configured to store test image data; a laser emitting unit including a laser light source configured to generate an imaging laser beam based on the test image data, the laser emitting unit being configured to project a test image onto a retina of an eyeball of a person subjected to an eye examination by using the imaging laser beam; an optical component configured to cause the imaging laser beam to converge at an inside of the eyeball of the person; a parameter acquiring unit configured to acquire parameter information for a retinal scanning type eyewear, the parameter information including angle information indicating a rotation angle of the laser emitting unit when the laser emitting unit is rotated around a converging point of the laser beam; and an output unit configured to output the parameter information to an external device.
