IMAGING APPARATUS FOR PARAMETER MEASUREMENT FOR SPECTACLE WEARING

Japanese Patent JP2015085163

A

PROBLEM TO BE SOLVED: To enable more proper measurement by creating a far vision state and a near vision state of a subject.SOLUTION: An imaging apparatus for spectacle parameter measurement of capturing an image for measuring a parameter for spectacle wearing, includes: a first measuring optical system which is provided with a fixation target for far vision of making a subject fixedly view in the far vision state and a first imaging element of imaging the subject set in the far vision state with the fixation target for far vision, guides the fixation target for far vision from the front surface direction to eyes to be inspected, and guides light from the subject to the first imaging element; and a second measuring optical system which is provided with a fixation target for near vision of making the subject fixedly view in the near vision state and a second imaging element of imaging the subject set in the near vision state with the fixation target for near vision independently of the fixation target for far vision and the first imaging element, guides the fixation target for near vision to the eyes to be inspected and guides light from the subject to the second imaging element. The first measuring optical system and the second measuring optical system are arranged independently of each other.
