| Abstract: | Hartmann test for progressive addition lenses is proposed in this paper.The measurement principle of Hartmann test for ophthalmic lenses and the power compensation of peripheral rays are introduced.The experimental setup used to test lenses is put forward and the sample images from CCD are obtained.The power distribution map for lenses can be obtained by image processing in theory.The results indicate that Hartmann test for progressive addition lenses is convenient and feasible,and its structure is simple. |
