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.
Abstract:
A modular worktop, and method of assembly, including a surface member, a front edge, and a backsplash, the components preferably being removably attached to each other. Each of the surface member, front edge, and backsplash may be selected from a predetermined group of decorative surfacing options, resulting in a worktop that is aesthetically pleasing to the consumer or person selecting the components. Additionally, each of the components is sized and configured so as to bring assembly and installation within the skill range of the average consumer. Because the front edge is removably attached, the front edge is changeable at the discretion of the consumer, for example, for aesthetic reasons.
