Abstract
An eyeball optical measuring device includes: an optical measuring unit that irradiates an eyeball of a subject with measuring light to perform an optical measurement of the eyeball; and a light irradiation unit that irradiates the eyeball with irradiation light prior to the optical measurement by the optical measuring unit, the irradiation light having a lower energy density than an energy density of the measuring light.
Claims16
An eyeball optical measuring device comprising:
- an optical measuring unit configured to irradiate an eyeball of a subject with measuring light to perform an optical measurement of the eyeball;
- and
- a light irradiation unit configured to irradiate the eyeball with irradiation light for making a pupil diameter of the eyeball smaller prior to the optical measurement by the optical measuring unit, the irradiation light having a lower energy density than an energy density of the measuring light,
- wherein the measuring light travels along an optical path in a direction intersecting another direction toward the fundus of the eyeball, the direction passing across an anterior chamber of the eyeball.
An eyeball optical measuring method for optically measuring an eyeball of a subject, comprising:
- irradiating the eyeball with irradiation light that has a lower energy density than an energy density of measuring light used for the optical measurement;
- and
- irradiating the eyeball with the measuring light to optically measure the eyeball,
- wherein the measuring light travels along an optical path in a direction intersecting another direction toward the fundus of the eyeball, the direction passing across an anterior chamber of the eyeball.
