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 ( ), receivers on the user ( ) providing data to the interface ( ). During a test a standard set of frames ( ) are used, as are near ( ) and intermediate ( ) distance reading planes.

Method and system for prescribing and/or dispensing ophthalmic lenses

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 &plusmn;22.5&deg; 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.
