Abstract
An ophthalmic apparatus comprising an input unit with which data on eye refractive power distribution of an eye to be examined at far vision, which is an unaccommodated state of the eye, and data on eye refractive power distribution of the eye at near vision, which is an accommodated state of the eye are inputted, a display, and a calculation and control unit which obtains data on distribution of difference between both the inputted data on distribution, so as to display at least one of the following data on the display: the data on the eye refractive power distribution at far vision; the data on the eye refractive power distribution at near vision; and the obtained data on the distribution of difference.
Claims9
An ophthalmic apparatus comprising:
- an input unit with which data on eye refractive power distribution of an eye to be examined at far vision, which is an unaccommodated state of the eye, and data on eye refractive power distribution of the eye at near vision, which is an accommodated state of the eye are inputted;
- a display;
- and
- a calculation and control unit which obtains data on distribution of difference between both the inputted data on distribution, so as to display at least one of the following data on the display:
- the data on the eye refractive power distribution at far vision;
- the data on the eye refractive power distribution at near vision;
- and the obtained data on the distribution of difference.
An ophthalmic apparatus comprising:
- a projecting optical system for projecting a measurement target on a fundus of an eye to be examined;
- a detecting optical system for detecting an image of the measurement target formed on the fundus;
- a target presenting optical system for presenting a target to the eye at a variable distance;
- a display;
- and
- a calculation and control unit which obtains data on eye refractive power distribution over each portion of a cornea of the eye based on results detected by the detecting optical system, and further obtains data on distribution of difference between the data on eye refractive power distribution that have been obtained with the target presented at different distances, so as to display at least the obtained data on the distribution of difference.
