A method () of dispensing an ophthalmic lens for a wearer is disclosed. The method () includes 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 and processing () 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 () is also disclosed.

Ophthalmic lens dispensing method and system

A method of designing and/or selecting a progressive addition lens design for a wearer is disclosed. In an embodiment, the method includes displaying a graphical representation of an initial progressive addition lens design including design parameters having design values. A user interface is provided including, for each of one or more of the design parameters, a control that is adjustable over a range of levels, each level in the range being associated with a corresponding value of the respective design parameter. A control is adjusted to select a level and the selection is processed so as to substantially simultaneously update the displayed graphical representation in accordance with the selected level to provide a modified progressive lens design. A system for designing and/or selecting a progressive addition lens design for a wearer is also disclosed.

Ophthalmic lens design and/or dispensing

A method for testing a person's vision is disclosed. The method includes providing, for display to the person, one or more sequences of test images, each test image including one or more test symbols. For each test image, a target symbol is identified to the person. The person then views each test image in the sequence and activates a control in response to recognizing a test symbol that replicates the shape of the target symbol. At the completion of the sequence, a parameter value associated with the activations is processed and correlated with a vision metric. A system for testing a person's vision is also disclosed.

Vision testing system and method

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.

Selecting and/or designing ophthalmic lenses

A method of simulating an optical effect, and/or characteristic of a selected ophthalmic lens design for a wearer is disclosed. In an embodiment, the method includes retrieving simulation data for the selected ophthalmic lens design and processing the simulation data to generate output image data for an output image simulating the optical effect and/or characteristic of the selected ophthalmic lens design. The output image is displayed, using a head-mounted display worn by the wearer, for viewing by the wearer. A system for simulating an optical effect, and/or characteristic of a selected ophthalmic lens design for a wearer is also disclosed.

Ophthalmic lens simulation system and method

An ophthalmic lens element () for correcting myopia in a wearer's eye is disclosed. The lens element () includes a central zone () and a peripheral zone (). The central zone () provides a first optical correction for substantially correcting myopia associated with the foveal region of the wearer's eye. The peripheral zone () surrounds the central zone () and provides a second optical correction for substantially correcting myopia or hyperopia associated with a peripheral region of the retina of the wearer's eye. A system and method for dispensing or designing an ophthalmic lens element for correcting myopia in a wearer's eye is also disclosed.

Ophthalmic lens element for myopia correction

A method and system for designing a progressive lens is disclosed. The method includes modifying a reference progressive lens design having a peripheral design which is suitable for a wearer and design features with known values. The modification of the reference progressive lens design provides a new progressive lens design in which at least one of the design features have been customized according to the wearer's preference. The new progressive lens design has substantially the same peripheral design as the reference progressive lens design.

Method of designing progressive lenses

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.

Progressive lens

A progressive ophthalmic lens element including a lens surface having an upper viewing zone having a surface to achieve a refracting power corresponding to distance vision, a lower viewing zone having a greater surface power than the upper viewing zone to achieve a refracting power corresponding to near vision, and an intermediate zon extending across the lens element having a surface power varying from that of the upper viewing zone to that of the lower viewing zone and including a corridor of relatively low surface astigmatism, the progressive ophthalmic lens element including progressive design elements selected to reduce myopia progression.
