Problems solved by technology

However, these coatings do not provide adequate protection
Additionally, these conventional coatings alter the geometry and thus the optical design of the optic
As a result, optics may no longer deliver the optical goals they were designed to meet

Embodiment Construction

[0029] refer to Figure 1A to Figure 1C, shows a first embodiment 10a of the optical article of the present invention. Optical article 10a can include primary optical layer 34 having opposing first and second primary optical surfaces 42a and 42b and film layer 38 having opposing first and second film surfaces 46a and 46b. Optical article 10a may have any suitable shape; for example, the optical article may be spherical, toric, or aspheric. To illustrate, optical article 10a may have inner surface 14 defined, for example, by first primary optical surface 42a and outer surface 18, for example defined by second film surface 46b. Inner surface 14 may be concave and outer surface 18 may be convex; however, in other embodiments, each of the inner and outer surfaces may be concave, convex, or flat, which Depends on the intended use of the optical article 10a.

[0030] Film layer 38 may be embossed such that first film surface 46a defines a plurality of concave optical elements 22a...

Abstract

The present disclosure includes optical articles comprising a film layer that has first and second film surfaces and is embossed such that the first film surface defines a plurality of concave optical elements and the second film surface defines a plurality of convex optical elements. The present optical articles can include one or more optical layers coupled to the film layer. Each of the optical layer(s) can encapsulate the concave optical elements or the convex optical elements.

Description

technical field [0001] The present invention relates generally to optical articles, particularly but not limited to optical articles comprising encapsulated optical elements defined by embossed films. Background technique [0002] Optical articles, such as lenses, can be used to correct refractive errors of the eye, such as nearsightedness, hyperopia, presbyopia, and astigmatism. Some lenses include optical elements (such as microlenses) on the lens surface that can assist in the correction of these refractive errors. For example, microlenses can provide a positive add value to focus a portion of incident light in front of the retina, thereby controlling myopia progression. [0003] Microlenses are also used in other applications. For example, microlenses are used in digital projectors, imaging devices (such as photocopiers and cell phone cameras), microscopes (such as for uniform illumination), displays, and to improve the light collection efficiency of CCD arrays, among ...
