Document Type and Number:
Japanese Patent JP2016025922
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method that enables a common spatial reference to be determined for a measured value while a parameter of an eye/spectacle system is detected by a plurality of different measurements using different units.SOLUTION: A method for determining an eyeball fulcrum position ADL of a subject's eye 10 includes: a step a) of determining a mean curvature of the cornea 16 of his/her eye 10; a step b) of determining a mean phase error of his/her eye 10; a step c) of determining an optic axis length LA from the mean curvature and the mean phase error; and a step d) of determining the eyeball fulcrum position ADL from the optic axis length LA.SELECTED DRAWING: Figure 2
