PURPOSE:To simplify observing and measuring work, and obtain instantly a measured value of an eye part to be examined in such an eyeball observing and measuring device as an optical photographing means to observe the eye part to be examined has image signal output. CONSTITUTION:An eyeball observing and measuring device is provided with plural different power objective lenses selected to observe and measure an eyeball, an optical photographing means 14 to output an eye part to be examined observed by the objective lenses as an image signal, a freeze means 18 which records and preserves image signal information from the optical photographing means 14 in a memory and outputs a still picture signal by taking out an image signal when it is selected and an operation means 20 to output a comparison scale fitted for power and measured value information corresponding to it according to power information of the objective lenses, and is provided with an image synthesizing means 16 to synthesize the comparison scale and the measured value information from the operation means 20 and the image signal from the optical photographing means 14 or the freeze means 18 and a display means 24 which displays a synthesized image and obtains the measured value information by comparing the eye part to be examined with the comparison scale in a sill picture. |
