    • 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.

    • An objective refraction measuring system of an ophthalmic apparatus measures a refractive power of an eye to be examined in an objective manner under the condition that a gazing chart of a gazing target system is fixed to the eye to be examined. An arithmetic-logic unit obtains an objective measurement value of the eye to be examined on the basis of the measurement result by the objective refraction measuring system and the gazing target system. A control unit controls a continuous objective measurement while fogging the gazing chart after setting the gazing chart of the gazing chart system to a far-sight position of the eye to be examined which is obtained by using the gazing target system. With such measurement, the continuous objective measurement values by fogging the gazing chart of the gazing target system is obtained from the far-sight position based upon the objective measurement of the eye to be examined. Thus, the limit of the adjustment force of the eye to be examined is precisely measured.
    • 眼科装置的客观折射测量系统在目标系统的注视图固定在待检眼上的条件下,以客观的方式测量被检眼的屈光度。 算术逻辑单元基于目标折射测量系统和注视目标系统的测量结果来获得要检查的眼睛的客观测量值。 控制单元控制连续的客观测量,同时在将注视图系统的注视图设置到通过使用注视目标系统获得的被检眼的远视位置之后使注视图发生雾化。 通过这样的测量,基于要检查的眼睛的客观测量,从远景位置获得通过使注视目标系统的注视图发生雾化的连续客观测量值。 因此,精确地测量被检眼的调节力的极限。
