Title:
OPHTHALMIC DEVICE
Document Type and Number:
Japanese Patent JP3580928
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To allow an ordinary subject to easily understand his/her own sight condition by relating measurement data of a near point meter to those of an objective perimetry ocular refraction measuring device or a lens meter.
SOLUTION: An adjustment limit of tested eyes at near distance is measured with the near point measuring means of a near point meter 1. Objective perimetry value information and glass value information related to the ocular refraction of tested eyes are measured with an objective perimetry ocular refraction measuring device 30 and a lens meter 33, and the information is inputted via an IC card 32. An input control circuit 40 obtains a far point distance of tested eyes based on the input information related to the ocular refraction of eyes tested, then creates a picture of visual field of tested eyes based on the far point distance and the near point distance of the near point measuring means, and print it out from a printer 24.
