| 20120069297 | EYEGLASS PRESCRIPTION METHOD - In general, in some embodiments, the disclosure provides a method that includes making a subjective refraction of a person to determine information about the person's vision, making a wavefront measurement of one or both of the person's eyes to determine information about the optical properties of one or both of the person's eyes (e.g., aberrations), calculating a prescription for the person based on the information about the person's vision and the information about the optical properties of one or both of the person's eyes, and outputting the prescription. | 03-22-2012 |
| 20100039614 | SYSTEM AND METHOD FOR PRESCRIPTION OF VISUAL AIDS - In one aspect, the invention features a method for determining an eyeglass prescription for an eye. The method includes obtaining a measurement of a wavefront indicative of the refractive properties of the eye, establishing an optimization space corresponding to a plurality of possible prescriptions for the eye, determining a value for a merit function for each of the possible prescriptions in the optimization space, where the merit function value corresponds to a visual function of the eye when corrected using the corresponding possible prescription, generating a representation of the merit function values, and outputting the representation to an eye care professional. | 02-18-2010 |
| 20100030570 | SYSTEMS AND METHODS FOR ORDERING LENSES - Methods for dispensing eyeglasses are disclosed. The methods involve making a subjective refraction and an objective refraction and sending the information to a calculation computer to combine both refractions to calculate the person's prescription. The person's prescription is subsequently sent to a manufacturing location separate from the calculation computer for manufacture of the lenses. | 02-04-2010 |
| 20090015787 | APPARATUS AND METHOD FOR DETERMINING AN EYEGLASS PRESCRIPTION FOR A VISION DEFECT OF AN EYE - The disclosure relates to a method for determining an eyeglass prescription for a vision defect of an eye. In certain embodiments, the method includes optimizing a caustic in the area of the retina of the eye for a light ray passing through the eyeglass prescription and the eye. The disclosure further relates to an apparatus that is suitable for carrying out the method. | 01-15-2009 |
| 20080231802 | EYEGLASS PRESCRIPTION METHOD - In general, in some embodiments, the disclosure provides a method that includes making a subjective refraction of a person to determine information about the person's vision, making a wavefront measurement of one or both of the person's eyes to determine information about the optical properties of one or both of the person's eyes (e.g., aberrations), calculating a prescription for the person based on the information about the person's vision and the information about the optical properties of one or both of the person's eyes, and outputting the prescription. | 09-25-2008 |
