Abstract
The use of standard CCD cameras and image digitalization and processing on medical diagnosis are more and more frequent. The correction of human eye's refraction problems by the use of contact lenses is generalized. In spite its advantages in terms of users comfort, special care must be taken on its prescription and adaptation. Astigmatic eyes often place the highest problems. A careful assessment of the quality of the lens to cornea adaptation must to be performed. The basic and more traditional way to check the contact lens' fitting is to perform a fluorescein test. We intend to make the process more convenient for both patient and optometrist. The fluorescence images are acquired by a CCD camera and then digitized and processed in order to produce a semi- automated process.
