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.

Abstract: A progressive ophthalmic lens including a far vision zone, a near vision zone and an intermediate vision zone is provided having a relatively high, relatively wide near vision zone and a relatively wide intermediate zone. A surface correction(s) for reducing optical aberrations in peripheral regions of the lens may be provided within a pair of generally horizontally disposed opposed segments approximately ±22.5° above and below a generally horizontally axis passing through a fitting cross. Two or more progress ophthalmic lenses differing in prescribed addition power may be placed in series to provide a range of distance prescriptions for one or more of emmetropes, hyperopes and myopes. A method of designing the progressive ophthalmic lens is also disclosed.
