Abstract: A scanning laser ophthalmoscope includes a light source that irradiates measurement light; a scanner that sequentially irradiates the measurement light to the eye by adjusting the reflection angle of the measurement light; an objective lens unit that focuses the measurement light reflected from the scanner to form the focus of the measurement light on the retina of the eye; and a light detector that detects retinal reflection light. The objective lens unit includes a first objective lens inclined at a first angle with the vertical direction of the traveling path of the measurement light, a second objective lens inclined at a second angle therewith, and a third objective lens positioned in the vertical direction of the traveling path of the measurement light. The inclination angles of the first and second objective lenses are in opposite directions with respect to the vertical direction of the traveling path of the measurement light.

Abstract: A photorefraction vision screening device for examining visual diseases by performing pupil detection and refraction test of the eye includes a measurement light irradiator configured to irradiate measurement light to an eye to be examined; a measurement light controller configured to control light-emitting elements of the measurement light irradiator; an image detector configured to detect an image formed on the retina of the eye to be examined by the measurement light having been irradiated from the light-emitting elements of the measurement light irradiator and having passed through the pupil of the eye to be examined; and a calculation part configured to calculate refractive power of the eye to be examined based on the image of the measurement light detected by the image detector.
