摘要：
An optimized contact lens design and method which leverages the strainenergy of the system when placed on eye that improves centration, translation,and stabilization characteristics, or any combination thereof, in order toimproveboth comfort and vision. A contact lens design and methodology wherein thelens-eye resulting strain energy is optimized to achieve the desired functionbe itcentration, translation, or stabilization. Since the lens strain energy isdirectlydriven by the amount of lens deformation, it is possible to control the lensstrainenergy through the modulus of the material, design of the lens geometry,namelythe radii or curvature, peripheral thickness profiles, edge or rim shapes. Thesurface pressure and/or lens strain energy can be optimized for a givenpopulationby averaging the ocular eye shape/surface. Alternatively the lens strainenergycan be optimized for a single given eye (i.e., custom design).
