Abstract: Methods for ophthalmic lens design incorporating a visual acuity profile are disclosed. The methods include applying rules and functions to visual acuity profile data and an ophthalmic prescription to generate ophthalmic lens parameters for a subject. The visual acuity profile data includes a maximum visual acuity for the subject. The visual acuity profile data may also include a focus tolerance or tolerable blur. Tolerable blur may be measured by an ophthalmic professional or extrapolated. The visual acuity profile data may also include eye physical data such as pupil diameter and eye size, accommodation, retinal photoreceptor cell packing information and neural processing information. The visual acuity profile data may also include personal biographic and/or medical information for the subject.

Abstract: Methods for lens configuration are disclosed. A method includes erasing a lens by heating the lens to a defined erasure temperature and writing a refractive index spatial distribution in the lens using an exposure pattern of directed ultraviolet (UV) light. The lens may be used as an ophthalmic lens or a lens used in industry. The lens comprises a rewriteable material, including, for example, liquid crystals. The lens may be erased using heat of a defined temperature. The lens may be rewritten by applying other exposure patterns to the lens using UV light.

Abstract: An improved method for configuring progressive ophthalmic lenses is disclosed. The method includes computing a traditional merit function with two changes. First, the merit function computation is limited by calculating only a preferred distance from the meridian rather than until 0. Second, an additional term is added to the merit function that calculates the mean sphere at a point that is at a reduced range from the maximum unwanted cylinder, rather than the entire range.

Abstract: There is disclosed a method for recommending ophthalmic lens parameters. The method includes receiving user data from a plurality of lens wearers, receiving lens configuration information, and receiving satisfaction information for a plurality of lens wearers. The user data and satisfaction information are analyzed to identify and/or determine lens features based on correlations in the user data and the satisfaction information, including repeating the analyzing when additional user data and additional satisfaction information is received and/or on a regular basis. When new wearer information including a lens prescription for a new wearer and user data for the new wearer is received, lens parameters are produced for the new wearer including evaluating lens manufacturing characteristics based on the analyzing in correlation with the new wearer information.
