Method for designing non spherical soft contact lenses

摘要

Abstract a method for optimizing the performance in centration, rotation and stability of contact lenses makes use of the upper and lower eyelid geometries to maximize the lens lid interaction for two different contact lens positions on the eye. The contact lenses are non round lenses for maximum interaction with the eyelids.* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * the translation of the summary summary patent invention: "method to design non spherical soft contact lenses.The present invention relates to a method to optimize performance in alignment, rotation and stability of lenses that contact which makes use of the geometries of the upper and lower eyelids to maximize interaction lens rims for two different positions of the contact lens in olh O. the contact lenses are non spherical lenses for maximum interaction with eyelids.
