Patent ID: 7648240

Claim:
An ophthalmic apparatus comprising: a projection system in which a pattern member is provided with a predetermined pattern for measuring the shape of a cornea of an eye of a subject, the predetermined pattern being thereby projected on the cornea of the eye of the subject; and an optical observation system in which light flux having a shape of the predetermined pattern emitted from the projection system is reflected at the cornea of the eye of the subject, the eye of the subject being observed by the light reflected by the cornea, a measurement and projection optical system for projecting a ring image on an eye ground of the eye of the subject: and an arithmetic unit functioning for calculating the shape of the cornea of the eye of the subject based on the light reflected by the cornea, the arithmetic unit functioning for calculating a refractive power of the eye based on the ring image projected on the eye ground of the eye of the subject, wherein the pattern member has a surface at a side of the eye of the subject, and the surface is coated with a paint having a filtering property that transmits infrared light by 80% or more and absorbs visible light so as to block the visible light by 90% or more, whereby the subject is prevented from seeing the predetermined pattern of the pattern member and the refractive power of the eye is precisely measured without causing an accommodation effect of the eye of the subject.
