Abstract
An optical measurement apparatus for an eyeball includes a light emitter, a light receiver, a detector, and a controller. The light emitter emits light such that the light passes across an eyeball of a subject. The light receiver receives the light that has transmitted through the eyeball. The detector detects a direction of the eyeball. The controller performs control such that the light emitter starts emitting light having an intensity used in measurement or the light emitter increases an intensity of light emitted by the light emitter to the intensity used in measurement in a case where the direction of the eyeball detected by the detector is in a predetermined range.
