The method includes the steps of providing a measurement indicative of the refractive properties of the eye; establishing an optimization space corresponding to a plurality of possible eyeglass prescriptions for the eye; determining a merit function, wherein a value of the merit function corresponds to a visual function of the eye when corrected using one of the plurality of possible eyeglass prescriptions within the optimization space, wherein the merit function includes a term depending on a magnitude of a corrective astigmatism of the one of the plurality of possible eyeglass prescriptions and causing a less optimal value of the merit function the higher the magnitude of the corrective astigmatism and/or the higher the magnitude of a difference between the corrective astigmatism and a subjective corrective astigmatism; and determining the eyeglass prescription by optimizing the value of the merit function. The invention is further directed to a system for determining an eyeglass prescription and a corresponding computer program product. | 2015-12-03 |
20150346513 | Carbon Dioxide Sensing Color Changeable Dyes For Indicating Exposure, Methods of Making and Using Such Dyes, and Apparatuses Incorporating Such Dye - According to embodiments of the present application, a carbon dioxide sensing color changeable dye can comprise a carbon dioxide status indicator, a solvent, a polymer wherein the carbon dioxide status indicator is dispersed, an optional plasticizer, and an optional agent to facilitate mixing. The color changeable dye is a first color in the presence of a carbon dioxide rich environment and is capable of changing to a second color upon exposure to atmospheric condition for a period of time corresponding to the intended use time of a restricted, disposable or limited use product. Methods of making and using the color changeable dye and apparatuses incorporating such dye are also disclosed. | 2015-12-03 |
