Abstract
The ophthalmic optical system is configured to apply an angular scanning light ray to an eye. M=|ωout/ωin| is defined, where ωin represents an angle between an incident light ray to the ophthalmic optical system and an optical axis of the ophthalmic optical system, and ωout represents an angle between an exiting light ray exiting from the ophthalmic optical system toward the eye and the optical axis. The ophthalmic optical system satisfies a conditional expression Mpar<Mmax, where Mpar represents M in a case that the incident light ray is a paraxial ray, Mmax represents M in a case that the incident light ray is a ray of a maximum angle of win.
