Patent number: 10379381Abstract: An optimized contact lens design and method which leverages the strain energy of the system when placed on eye that improves centration, translation, and stabilization characteristics, or any combination thereof, in order to improve both comfort and vision. A contact lens design and methodology wherein the lens-eye resulting strain energy is optimized to achieve the desired function be it centration, translation, or stabilization. Since the lens strain energy is directly driven by the amount of lens deformation, it is possible to control the lens strain energy through the modulus of the material, design of the lens geometry, namely the radii or curvature, peripheral thickness profiles, edge or rim shapes. The surface pressure and/or lens strain energy can be optimized for a given population by averaging the ocular eye shape/surface. Alternatively the lens strain energy can be optimized for a single given eye (i.e., custom design).Type: GrantFiled: June 8, 2015Date of Patent: August 13, 2019Assignee: Johnson & Johnson Vision Care, Inc.Inventors: Pierre-Yves Gerligand, Gregory J.

Patent number: 10335027Abstract: In exemplary implementations of this invention, an aberrometer is used to measure the refractive condition of any eye. An artificial light source emits light that travels to a light sensor. Along the way, the light enters and then exits the eye, passes through or is reflected from one or more spatial light modulators (SLMs), and passes through an objective lens-system. The SLMs modify a bokeh effect of the imaging system (which is only visible when the system is out-of-focus), creating a blurred version of the SLM patterns. The light sensor then captures one or more out-of-focus images. If there are refractive aberrations in the eye, these aberrations cause the SLM patterns captured in the images to be distorted. By analyzing differences between the distorted captured patterns and the undistorted SLM patterns, refractive aberrations of the eye can be computed and an eyewear measurement generated.Type: GrantFiled: April 10, 2014Date of Patent: July 2, 2019Assignee: EYENETRA, INC.Inventors: Vitor Pamplona, Ramesh Raskar
