METHOD FOR EVALUATING AN OCULAR OPTICAL LENS, AN APPARATUS AND A MEMORY MEDIUM THEREFOR |
摘要 |
To display the difference in the Abbe number of an ocular optical lens usi ng the area of a region and to facilitate visual understanding of the differenc e in the Abbe number. The Abbe number indicating the degree of chromatic aberration at each point of a spectacle lens is input and a region of comfortable vision marked out with and contained in a circle, an ellipse or a closed curve is obtained based on the input value. A plurality of the data are derived using a plurality of spectacle lenses having different Abbe numbers. On the same screen having the shape of a spectacle frame 80, a plurality of regions for comfortable vision 81 and 82 marked out with and contained in a circle, an ellipse or a closed curve 81a and 82a, respectively, are formed and the difference in the vision due to the difference in the Abbe number is evaluated from the area of the region.
