Abstract: The present invention involves the prescribing and/or dispensing ophthalmic lenses, such as progressive addition lenses, for a wearer. In one form of the invention lens usage information is obtained from a wearer and entered into a programmed computer. The programmed computer processes the lens usage information to provide a separate weighted lifestyle score for each of one or more respective lifestyle score categories, such that each weighted lifestyle score is a function of a predetermined relationship between the respective lifestyle score category and at least ophthalmic lens design feature. The programmed computer then selects or designs an ophthalmic lens design using one or more of the weighted lifestyle scores such that the selected or designed ophthalmic lens has at least one lens design feature which has been customised using one or more of the weighted lifestyle scores.

Abstract: A system and method for prescribing and/or dispensing ophthalmic lenses for a wearer. The method includes determining at least the wearer's individual visual behavioural patterns in terms of head movement and/or eye movement, processing those patterns with respect to a predetermined relationship between known head movements and/or eye movement characteristics and available ophthalmic lenses, such that the processing categorises wearers into a head movement or eye movement category that can then be used to produce a recommendation for an ophthalmic lens for the wearer. The system includes a transmitter unit (10), receivers on the user (12, 14) providing data to the interface (16). During a test a standard set of frames (18) are used, as are near (20) and intermediate (22) distance reading planes.
