  • Multi-imaging automated inspection methods and systems for wet ophthalmic lenses
    Patent number: 7990531
    Abstract: A method for inspecting lenses, especially wet contact lenses provided in a volume of liquid inside a container is described. A first image of the lens at a first position in the container is obtained, the lens then being moved to a second position within the container where a second image is obtained. A computer algorithm processes the first and second images to compare features that have moved with the lens to those features that have not moved with the lens whereby lenses are rejected if a feature has moved with the lens but is not a normal feature of the lens.
