<P>PROBLEM TO BE SOLVED: To provide an eye refracting power measuring device by which a precise measuring result can be obtained. <P>SOLUTION: The eye refracting power measuring device objectively measuring the refracting power of an eye to be measured has a projecting optical system having a measuring light source emitting the light beam for measuring the eye refracting power and projecting a measuring light beam to the fundus of the eye to be measured, a light receiving optical system allowing a 2D imaging element to receive the reflected light from the fundus of the eye by the measuring light beam as a 2D pattern image, a calculating means calculating the eye refracting power of the eye to be measured from the 2D pattern image received in the 2D imaging element by the light receiving optical system, the measuring light source is a superluminescent diode or a laser diode having a central wavelength of 850 to 940 nm. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
