  • Patent number: 9057886
    Abstract: Embodiments of the invention pertain to a method for producing a spectacle lens with optimal correction across the entire lens that take the patient's complete measured wavefront into account. Specific embodiments also consider one or more additional factors such as vertex distance, intermediate power, add power, segmental fitting height, pantoscopic tilt, and use conditions. The lens wavefront can be achieved by optimizing a corrected wavefront, where the corrected wavefront is the effect of the patient's measured wavefront and/or the lens wavefront. The optimization of the corrected wavefront can involve representing the measured wavefront and/or the lens wavefront on a grid. In an exemplary embodiment, the grid can lie in a plane. During the optimization, a subset of the grid can be used for the representation of the measured wavefront at a point on the grid so that the portions of the measured wavefront that contribute to the corrected wavefront at that point on the grid are taken into account.

  • Patent number: 8992013
    Abstract: Embodiments of the invention pertain to a method for producing a spectacle lens with optimal correction across the entire lens taking into account the patient's complete measured wavefront. Specific embodiments can also take into account one or more additional factors such as vertex distance, segmental fitting height, pantoscopic tilt, and use conditions. The lens wavefront can be achieved by optimizing a corrected wavefront, where the corrected wavefront is the combined effect of the patient's measured wavefront and the lens wavefront. The optimization of the corrected wavefront can involve representing the measured wavefront and the lens wavefront on a grid. In an embodiment, the grid can lie in a plane. During the optimization, a subset of the grid can be used for the representation of the measured wavefront at a point on the grid so as to take into account the portions of the measured wavefront that contribute to the corrected wavefront at that point on the grid.

  • Patent number: 8842370
    Abstract: The present invention relates to the optimization of human visual function by correcting and/or optimizing high-order optical aberrations in high performance optical devices. The optimization is particularly useful for high performance devices used under low light conditions such as binoculars, rifle scopes, telescopes, microscopes, night vision goggles and laser eye protection devices.

  • Publication number: 20140257839
    Abstract: A computerized online lens ordering system is provided. A patient portal allows a user to enter identifying information and/or healthcare plan information and a purchase selection for eyeglasses and/or contact lenses. A vision plan eligibility module submits claims to an insurer based upon the healthcare plan information, determines an amount due by the patient, if any, based upon the purchase selection, receives any payment due and authorizes an order. An fulfillment module, for eyeglasses, obtains the patient's prescription and frame biometric measurements, produces a lens fabrication pattern for the lenses, automatically orders the selected frame and fabrication of the lenses based upon the fabrication pattern, and delivers a fabricated pair either directly to the patient or to an eye care professional business. For contact lenses, the fulfillment module automatically orders delivery of the contact lenses either directly to the patient or to an eye care professional business.

  • Patent number: 8541526
    Abstract: Disclosed herein are photopolymerizable compositions and formulations that comprise photochromic dyes, photochromic blue light blocking dyes, permanent dyes, permanent blue blocking dyes, and/or their combinations. In some variations, these formulations are suited for example, for sandwiching between lens blanks to form semi-finished lens assemblies to form a tinted lens useful in sunglasses. The formulations are also suitable for correcting optical aberrations, and may provide a photochromic effect when exposed to sunlight.
