Title:
OPTOMETRIC APPARATUS
Document Type and Number:
Japanese Patent JP2015029527
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optometric apparatus capable of suppressing the burden on the examiner and subject when measuring the addition diopter of the subject's eye.SOLUTION: An optometric apparatus is provided with a target presenting optical system (correction optical system) for correcting the refraction error of a subject's eye, the target presenting optical system being capable of correcting the refraction error of the subject's eye to subjectively measure the addition diopter of the subject's eye (S10). When the addition diopter of the subject's eye is measured subjectively, the CPU of the optometric apparatus sets, on the basis of the adjustment force measured by an objective refraction test, the initial value of the addition diopter added to the subject's eye through the correction the refraction error by the target presenting optical system (S9).
