    摘要： An improved eye refractive power measuring apparatus is disclosed. The apparatus includes a measurement system for projecting a measurement target image to the retina of an eye to be tested and measuring the refractivity of the eye to be tested by detecting the focussing state of the measuring target image. In addition, it has an eye position detection system for detecting a shifted amount from a proper position of the eye to be tested and an arrangement for correcting a measurement result of the eye refractivity based on such detected result.

    摘要： An observation apparatus is provided. An apex angle of a contact prism is inputted by operating an apex angle setting knob of a control panel. A fining angle of the contact prism is inputted by operating a fitting angle setting knob. A control unit determines the amount of correction for astigmatism of a left observation optical system and the amount of correction for astigmatism of a right observation optical system based on a recognized observation magnification and the inputted apex angle. An axial angle for the astigmatism of the left observation optical system and an axial angle for the astigmatism of the right observation optical system are determined based on the inputted fitting angle. Variable cross cylinder lens rotating drive units are controlled to rotate cylinder lenses of each of the right and left observation optical systems, thereby obtaining the determined axial angle and the determined amount of correction.

    摘要： Disclosed is a subjective optometric apparatus in which the earpiece members and the nose pad member for attaching the main body of the device to the subject can be easily adjusted without involving any effort. The subjective optometric apparatus has a horizontal frame and an inner tube inserted into the horizontal frame, with a support bar for supporting a nose pad member being passed through the horizontal frame and the inner tube. In a state in which the inner tube is being biased by a spring, a rubber member provided in a through-hole of the inner tube abuts the peripheral surface of the support bar to lock the support bar, thereby bringing the nose pad member into a locked state. Further, when a push-button is pushed in against the biasing force of the spring, the inner tube is displaced and the rubber member is detached from the peripheral surface of the support bar, with the result that the nose pad member is released from the locked state and becomes capable of being displaced.

    摘要： An observation apparatus capable of preferably removing an astigmatism and chromatic aberration which occur in an observation image is provided. An apex angle of a contact prism is inputted by operating an apex angle setting knob of a control panel. A fitting angle of the contact prism is inputted by operating a fitting angle setting knob. A control unit determines the amount of correction for astigmatism of a left observation optical system and the amount of correction for astigmatism of a right observation optical system based on a recognized observation magnification and the inputted apex angle. An axial angle for the astigmatism of the left observation optical system and an axial angle for the astigmatism of the right observation optical system are determined based on the inputted fitting angle. Variable cross cylinder lens rotating drive units are controlled to rotate cylinder lenses of each of the right and left observation optical systems, thereby obtaining the determined axial angle and the determined amount of correction.
