Ophthalmic lens dispensing method and system
First Claim
Patent Images
1. A method of dispensing an ophthalmic lens for a wearer, the method including:
- measuring the relative location of, and/or relationship between, selected anatomical features of a wearer'"'"'s head or face to obtain one or more measurement values for generating a contour map representing a frontal aspect of the wearer'"'"'s head or the wearer'"'"'s face;
processing the one or more measurement values to design and/or select an ophthalmic lens having a shape, wherein the shape is a three-dimensional optical surface shape, that depends on the measured values to substantially conform with the contour map, wherein the measurement values are matched to appropriate features of the shape of the ophthalmic lens; and
dispensing the ophthalmic lens to the wearer.

Abstract
A method (100) of dispensing an ophthalmic lens for a wearer is disclosed. The method (100) includes measuring (104) the relative location of, and/or relationship between, selected anatomical features of a wearer'"'"'s head or face to obtain one or more measurement values and processing (106) the one or more measurement values to design and/or select an ophthalmic lens having a shape that depends on the measured values. The ophthalmic lens element is then dispensed to the wearer. A dispensing system (200) is also disclosed.

21. A system for dispensing an ophthalmic lens for a wearer, the system including:
-
a measuring apparatus for measuring the relative location of, and/or relationship between, selected anatomical features of a wearer'"'"'s head or face to obtain one or more measurement values for generating an approximation of a contour map representing a frontal aspect of the wearer'"'"'s head or the wearer'"'"'s face; and a processing device for processing the one or more measurement values to dispense the ophthalmic lens, the dispensing including selecting or designing an ophthalmic lens having a shape, wherein the shape is a three-dimensional optical surface shape, that depends on the one or more measured values to substantially conform with the contour map, wherein the measurement values are matched to appropriate features of shape of the ophthalmic lens. - View Dependent Claims (22, 23, 30)

25. An integrated scanning and processing system for selecting and/or designing an ophthalmic lens for dispensing to a wearer, the system including:
-
a scanning device for scanning the wearer'"'"'s head or face to provide three-dimensional scan data; an input device for inputting or selecting anatomical features of the wearer'"'"'s face or head; and a processing device for obtaining, from the three-dimensional scan data, one or more measurement values expressing the relative location of, and/or the relationship between, the anatomical features and to process the measurement values to design and/or select an ophthalmic lens for dispensing, the ophthalmic lens having a shape, wherein the shape is a three-dimensional optical surface shape, that depends on the measured values, wherein the measurement values are matched to appropriate features of the shape of the ophthalmic lens. - View Dependent Claims (32)
