PROBLEM TO BE SOLVED: To provide an ophthalmic device which can provide by itself various kinds of bioinformation about an eye that a plurality of conventional devices determine to provide.
SOLUTION: The ophthalmic device is a device which does not need to touch an eye to provide bioinformation of the eye to examine, and comprises a cornea irradiation optical system, an eyeground irradiation optical system, a light path length changing means, an interference optical system, and a bioinformation providing system, wherein the cornea irradiation optical system has a low coherent light source and focuses light flux from the source on the area around a cornea the eyeground irradiation optical system irradiates a part of light flux from the source toward the eyeground the light path length changing means is positioned in the cornea irradiation optical system or the eyeground irradiation optical system and changes a light path length the interference optical system synthesizes a cornea reflection light provided by the cornea irradiation optical system and an eyeground reflection light provided by the eyeground irradiation optical system to interfere and separates spectroscopically the interfered light into frequency components and the bioinformation providing system uses Fourier transform to analyze a received light signal provided by the interference optical system and bases the analysis result and a change in light path length provided by the light path length changing means to provide bioinformation of the eye to examine.
