英文摘要 | The curvature of the eyeball in the ophthalmology filed is essential data, especially for human beings when they are being tested for wearing contact lens. It is extremely difficult to precisely measure the curvature of the eyeball because the measurement of the cornea, using a contact tool, is not possible. In this paper, we propose a method to calculate the curvature using the lens aberration theory and an image processing technique. We project the equal division circular zone plate on to the cornea. The reflective image did not have an equal division when distorted. The distortion value contains the curvature messages. |
