20100321483 | METHODS FOR THE TRANSFORMATION OF MEASURED VALUES OF A CHARACTERISTIC OF THE CORNEA AND APPARATUS FOR THE MEASUREMENT OF THE TOPOGRAPHY OF THE CORNEA - A method for the transformation of measured values of a characteristic of the cornea and apparatus for measuring the topography of the cornea. The method involves using a parameterized assignment rule, providing a slider as an operating control, determining a current setting of the slider, and determining a parameter of the assignment rule based on the determined setting of the slider. The observer can sift through a large number of variants of the assignment rule within a short time without prior knowledge by means of the slider to extract information at different parameter settings in an economical manner. | 12-23-2010 |
20120287398 | HEADS-UP VISION ANALYZER - A binocular vision analyzer apparatus is used for determining a prescription of visual aids for the eyes of an individual. The apparatus includes first and second targets respectively corresponding to the first and second eyes of the individual and at least one illuminator unit for illuminating the targets. An optical system is configured to present respective virtual images of the first and second targets so as to be viewable by the respective first and second eyes. At least one beam splitter disposed in front of the first and second eyes directs the virtual images toward the respective eyes. The apparatus also includes first and second spherical correction devices and first and second cylindrical correction devices that respectively correspond to the first and second eyes. | 11-15-2012 |
20140375949 | ANTI MYOPIA LENS - A pair of multifocal contact lenses, each including an optical zone portion and a stabilization zone portion. The optical zone portion has a distance prescription zone and a near prescription zone. The near prescription zone has a near vision add power appropriate to reduce accommodative effort to substantially zero for a selected working distance and convergence support having base-in prism combined between the pair of multifocal lenses appropriate to reduce convergence effort to substantially zero for the selected working distance. The stabilization zone portion is structured to maintain orientation of the pair of lenses with a base of the base in prism directed substantially nasally. | 12-25-2014 |
