<P>PROBLEM TO BE SOLVED: To provide a device for measuring the eye refracting power of an eye to be measured from the pattern image detected by a 2D light receiving element by which the light quantity is not required to be make strong, an image with a high S/N ratio can be acquired, and measuring precision can be enhanced. <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, and a calculating processing means acquiring a plurality of 2D pattern images photographed by the 2D light receiving element, mutually additionally processing the plurality of image data, and acquiring the eye refracting power of the eye to be measured from the acquired image data which has been additionally processed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
