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

In one aspect, the invention features a method for determining an eyeglass prescription for an eye. The method includes obtaining a measurement of a wavefront indicative of the refractive properties of the eye, establishing an optimization space corresponding to a plurality of possible prescriptions for the eye, determining a value for a merit function for each of the possible prescriptions in the optimization space, where the merit function value corresponds to a visual function of the eye when corrected using the corresponding possible prescription, generating a representation of the merit function values, and outputting the representation to an eye care professional.

System and method for prescription of visual aids

The present invention relates to novel ophthalmic lens elements and eyewear having wide field of view, low distortion, improved astigmatism correction where required and enhanced eye protection properties. Series of lens elements have steeply curved spherical reference surfaces. The edged lenses of the series have approximately consistent aperture size, shape and hollow depth across a range of common prescriptions. Novel sunglasses, laser protective eyewear, and lens edgings, coatings and frames are included in the invention.

Method of making wide field spherical lenses and protective eyewear

A progressive ophthalmic lens element including a lens surface having an upper viewing zone having a surface power to achieve a refracting power corresponding to distance vision, a lower viewing zone having a different surface power than the upper viewing zone to achieve a refracting power corresponding to near vision; and an intermediate zone extending across the lens element having a surface power varying from that of the upper viewing zone to that of the lower viewing zone one or more of the upper, intermediate and lower viewing zones being designed optically to reduce or minimise a selected measure of blur for the corresponding range of object distances; and at least a portion of the peripheral region of the surface of the ophthalmic lens element being designed to reduce or minimise one or more surface characteristics known to correlate with the sensation of swim.

Balanced progressive lens

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

Shaped ophthalmic lenses

Spectacles, frames and methods for providing the same are disclosed. The frames have a shape adapted for engagement of wrap-around lenses having significant changes in base curvature in the field of vision of the wearer.

Spectacle frames for shaped lenses defined by monoformal carrier surfaces

Wide field spherical lenses and protective eyewear

A series of progressive opthalmatic lens elements, each lens element including a lens surface having an upper viewing zone having a surface power 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; a corridor of relatively low surface astigmatism connecting the upper and lower zones, said corridor having a surface power varying from that of the upper viewing zone to that of the lower viewing zone; the progressive opthalmatic lens series including a first set of lens elements having a base curve(s) suitable for use in providing a range of distance prescriptions for a first category of patient; and a second set of lens elements having a base curve(s) suitable for use in providing a range of distance prescriptions for a second category of patient; each lens element within a set differing in prescribed addition power and including a progressive design, in at least one of the upper and lower viewing zones, depending upon the addition power of the lens element; the lens elements in the first set differing substantively in progressive design from the corresponding lens elements in the second set due to the differences in base curve(s).

The disclosure relates to spectacle frames including frames adapted to engage ovaline edges of lens elements having a toroidal or changing base curvature. In a preferred embodiment the frame shape corresponds to the edge of front surfaces of a pair of lens elements having a high curvature which is common to various prescriptions.

Spectacles frames for shaped lens elements

Disclosed are novel molding methods for injection molding thermoplastic lens elements and particularly adapted for the manufacture of steeply curved and/or thin-centered lenses.

The present invention relates to novel ophthalmic lens elements and eyewear having wide field of view, low distortion, improved astigmatism correction where required and enhanced eye protection properties. Series of lens elements have steeply curved spherical reference surfaces. The edged lenses of the series have approximately consistent aperture size, shape and hollow depth across a range of common prescriptions.
