    摘要: An eye-refractometer includes an objective optic having a first optical path, an apertured mirror for dividing the first optical path into a second optical path and a third optical path, a mask disposed in the second optical path and having linear marks orientated in at least three directions, a radiation source for illuminating the mask, a mask disposed in the third optical path and having liner detecting areas orientated in at least three directions and photocells arranged behind the respective areas. Improvements in this eye-refractometer comprise an apertured plate disposed between the apertured mirror and one of above said masks and an annular apertured plate disposed between said apertured mirror and the other mask. Another improvement is found in that the length of the linear detecting area is shorter than the length of optimum focused images of the linear marks.

    摘要: An automatic eye-refractometer includes a projector for projecting a test pattern onto the fundus of an eye to be examined, a photo-electric device disposed to receive an image of the test pattern reflected upon the fundus of the eye, a calculator for calculating the refractive power of the eye using outputs from the photo-electric device and a processor for processing the results of the calculation into digital video signals. The eye-refractometer is further provided with a video camera for image picking up the front part of the eye through an objective lens of the projector to produce video signals and a video display device for displaying on a screen a picture produced from the video signals. With the measuring apparatus, the examiner can observe the image of the front part of the eye to be examined and can properly arrange the eye and the objective lens to each other while watching the picture displayed on the screen. By putting the digital signals into the video display device from the processor there are also displayed on the screen numerals, characters or other symbols informing of the refractive power of the examined eye.
