Abstract
Light weight ophthalmic lenses include a curved back lens attached to a curved front lens assembly having a functional element. An ophthalmic lens includes a curved front lens assembly and a curved back lens. The curved front lens assembly has an essentially constant thickness, forms an external world-side convex surface of the ophthalmic lens, and includes a functional element operable to modify an image of a real world scene viewed via the ophthalmic lens. The curved back lens forms an external user-side surface of the ophthalmic lens, has a world-side convex surface that is shaped complementary to and interfaced with the front lens assembly, and provides a prescribed vision correction.
Claims16
An augmented reality lens comprising:
- a front lens assembly consisting essentially of a curved front lens and a curved augmented reality combiner embedded within the curved front lens or attached to the curved front lens, wherein the curved front lens forms an external world-side convex surface of the augmented reality lens, wherein the curved front lens has an essentially constant thickness between 0.8 mm to 1.0 mm and is formed from an impact resistance material so that the curved front lens provides impact resistance satisfying ANSI standards for safety eyewear, wherein the external world-side convex surface has a radius of curvature less than 300 mm, and wherein the curved augmented reality combiner is configured for overlaying virtual image content on a real world scene;
- and
- a curved back lens that forms an external user-side surface of the augmented reality lens, wherein the curved back lens has a world-side convex surface that is shaped complementary to and interfaced with the front lens assembly, wherein the curved back lens provides a prescribed vision correction for a user of the augmented reality lens, and wherein the curved back lens has a minimum thickness location at which the curved back lens has a thickness equal to or less than 0.25 mm.
An ophthalmic lens comprising:
- a first lens assembly consisting essentially of a curved front lens and an augmented reality combiner operable to modify an image of a real world scene viewed via the ophthalmic lens, wherein the first lens assembly forms an external world-side convex surface of the ophthalmic lens, and wherein the curved front lens has an essentially constant thickness between 0.8 mm to 1.0 mm and is formed from an impact resistance material so that the curved front lens provides impact resistance satisfying ANSI standards for safety eyewear;
- and
- a curved back lens that forms an external user-side surface of the ophthalmic lens, wherein the curved back lens has a world-side convex surface and provides vision correction for a user of the ophthalmic lens, and wherein the curved back lens has a minimum thickness location at which the curved back lens has a thickness equal to or less than 0.25 mm.
An augmented reality device comprising:
- an augmented reality lens comprising a first lens assembly and a curved back lens, wherein the first lens assembly consists essentially of a curved front lens and an augmented reality combiner configured for overlaying virtual image content on a real world scene, wherein the first lens assembly forms an external world-side convex surface of the augmented reality lens, wherein the curved front lens has an essentially constant thickness between 0.8 mm to 1.0 mm and is formed from an impact resistance material so that the curved front lens provides impact resistance satisfying ANSI standards for safety eyewear, wherein the curved back lens forms an external user-side surface of the augmented reality lens, wherein the curved back lens provides vision correction for a user of the augmented reality lens, and wherein the curved back lens has a minimum thickness location at which the curved back lens has a thickness equal to or less than 0.25 mm;
- a frame assembly that supports the augmented reality lens and is configured to be worn by a user of the augmented reality device;
- and
- electronics mounted to the frame assembly and operable to display the virtual image content via the augmented reality combiner.
