<P>PROBLEM TO BE SOLVED: To evaluate the effect of reducing aberration visibly and quantitatively and display which aberration is dominant in an easy-to-understand manner. <P>SOLUTION: A measuring member for wavefront aberration measures wavefront aberration including higher order aberration of the eyes to be examined from the photodetective signal of the photodetective part of the wavefront aberration measuring system. A display member has a selection mode to select higher-order aberration to be displayed from the wavefront aberration measured by the wavefront aberration measuring member. A simulation member calculates the degree of affection of the measured wavefront aberration element on eyes. The display member displays wavefront aberrations measured by the wavefront aberration measuring member for each higher-order aberration including arrow aberration, coma aberration, spherical aberration, astigmatism and tetra-foil respectively, and the affection of the higher-order aberration element calculated by the simulation member. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
