Eye measurement apparatus

摘要

An eye measurement apparatus includes: a subjective measurement optical system configured to subjectively measure an examinee's eye, the subjective measurement optical system including: a chart to be presented to the examinee's eye; and a glare light source for irradiating the examinee's eye with a glare light; and a control part configured to determine presence or absence of opacity in a light transmitting part of the examinee's eye and, when the presence of opacity is determined, to allow display of necessity for a glare test which is a subjective measurement to be performed in a state that the examinee's eye is irradiated with the glare light.

1. An eye refractive power measurement apparatus comprising:
a subjective measurement optical system configured to subjectively measure an examinee's eye, the subjective measurement optical system including:
a chart to be presented to the examinee's eye; anda glare light source for irradiating the examinee's eye with a glare light; an objective measurement optical system to objectively measure an eye refractive power of the examinee's eye, the objective measurement optical system including:
a light projecting optical system for projecting a measurement light toward a fundus of the examinee's eye; anda light receiving optical system including a light receiving device for receiving a fundus reflection light obtained by reflecting the measurement light by the fundus; and a control part configured to determine presence or absence of opacity in a light transmitting part of the examinee's eye based on a light receiving signal obtained by the fundus reflection light and, when the presence of opacity is determined, to allow display of necessity for a glare test which is a subjective measurement to be performed in a state that the examinee's eye is irradiated with the glare light.
