Abstract
Official abstract text for this publication.
A method for stabilizing contact lenses includes providing a lens design with a nominal set of stabilization zone parameters, applying a merit function to the lens design based on balancing moments of momentum, and creating a contact lens design with improved stabilization based on the application of the merit functions to the lens design with a nominal set of stabilization zone parameters.
First claim
Opening claim text (preview).
What is claimed is: 1. A contact lens designed with improved stabilization, the contact lens being stabilized by a method comprising: a) providing a lens design with an initial set of stabilization zone parameters, b) applying a merit function to the lens design based on balancing moments of momentum, the merit function including at least one of lens rotation and centration performance, lens stability around a resting position, or lens rotation and centration performance and stability around a resting position, c) creating a contact lens design with improved stabilization based on the application of the merit function to the lens design with an initial set of stabilization zone parameters, and d) conducting steps b and c iteratively over multiple blinking cycles, wherein a virtual model that simulates the effects of eye mechanics is used to determine the contact lens design and blinking is one of the eye mechanics and the simulated effects of blinking is used to adjust the stabilization.
