An eye-examining apparatus for diagnosing myopia capable of simultaneously measuring the corneal curvature, refractive power, and axial length of the eye to be examined includes a keratometer; a refractometer including an infrared measurement light source, a lens array, and a refractor sensor; an axial length measurement unit including a beam splitter, a reference mirror, and a light detector; and a computation unit configured to calculate the corneal curvature, refractive power, and axial length of the eye to be examined.
