Abstract: Systems and techniques are provided for a data matching system having a plurality of clients and a master catalog. In a learning phase of a client, the data matching system builds a client matching table for the client and matches the input request to a specific entry in a particular set of entries in the master catalog. In a post-learning phase of the client, the data matching system uses the client matching table to match the input request to a specific entry in a particular set of entries in the master catalog. In a specific implementation, the data matching system uses a two-step match to build the client matching table. In a first step, a plurality of a set of entries in the master catalog is selected for the input request. In a second step, a particular set of entries is selected using a confidence score.

Abstract: A flexible optical element adopting liquid crystals (LCs) as the materials for realizing electrically tunable optics is foldable. A method for manufacturing the flexible element includes patterned photo-polymerization. The LC optics can include a pair of LC layers with orthogonally aligned LC directors for polarizer-free properties, flexible polymeric alignment layers, flexible substrates, and a module for controlling the electric field. The lens power of the LC optics can be changed by controlling the distribution of electric field across the optical zone. Lens power control can be provided using combinations of electrode configurations, drive signals and anchoring strengths in the alignment layers.

Abstract: A contact lens has a central region and an annular region surrounding the central region, the central region having a first optical power and the annular region having a second optical power. In a method of measuring the add power, the wavefront aberration of the contact lens is measured; a polynomial is fitted to the measured wavefront aberration. Terms of the polynomial correspond to types of aberration comprising defocus and astigmatism and residual aberrations. The add power is calculated as a defocus corresponding to the residual aberrations.

Abstract: A wettable silicone hydrogel contact lens having a low ionoflux and low evaporation is manufactured by curing a silicone hydrogel polymerizable composition in a contact lens mold comprising front and back lens-forming surfaces, where one of the lens-forming surfaces has a higher polarity than the other lens-forming surface.

Abstract: The present disclosure provides systems and methods to aid in the resupply of product arrays, such as contact lenses. In an aspect, this is accomplished by providing a physical product array to a reseller. Additionally, a computer-operated application is provided that displays a virtual representation of the physical product array. The reseller can then manipulate the virtual storage array to more easily identify the specific product slots in the array that need to be restocked, and the application can interact directly with an ordering system for the product manufacturer to submit orders for fulfillment. In an aspect, the application stores the product attributes for each slot of the product array, so that a simple visual inspection of the physical array can be translated into the proper product without a reseller having to determine product attributes for the specific array slots.
