Ophthalmologic device for accurately positioning a contact lens to an eye

A measuring and inspecting device for ophthalmologic use comprising:

• a photographing means for photographing an anterior eye segment of a subject bearing a contact lens to be fitted;
• a first display means for displaying an image of the anterior eye segment of the subject and installed contact lens photographed by the photographing means;
• a first position-detecting means for processing the image of the anterior eye segment on said first display means to detect a position of a pupil;
• a second position-detecting means for processing the image of said contact lens on said first display means for detecting a position of the contact lens installed on the subject;
• a calculating means for calculating a relationship of relative positions between the pupil and the contact lens based on positions of the pupil and the contact lens detected by the first position-detecting means and the second position-detecting means;
• and a second display means for displaying the relationship of the relative position calculated by the calculating means.
