Abstract
The present invention generally provides systems, methods and ophthalmic lenses for image display of a virtual image, such as the display of a holographic image. According to the invention, an ophthalmic lens is advantageously configured for optimizing the visualization of said displayed virtual images.
Claims9
An Ophthalmic lens supply system for providing an ophthalmic lens configured to be fitted onto a frame and worn by a wearer, said ophthalmic lens comprising a holographic mirror and said frame comprising a build-in image source configured for illuminating said holographic mirror so as to cause, upon reflection onto said holographic mirror, the visualization of a virtual image by the wearer, said ophthalmic lens being configured for correcting the wearer's virtual vision, said supply system comprising:
- first processing means configured for placing an order of an ophthalmic lens, wherein said first processing means are located at a lens ordering side and comprise:
- inputting means configured to input wearer prescription data;
- inputting means configured to input frame data, wherein said frame data comprise at least one image source data;
- second processing means configured for providing lens data based upon wearer prescription data, wherein said second processing means are located at a lens determination side and comprise outputting means configured for outputting said lens data, and
- first transmission means configured for transmitting said wearer prescription data and for transmitting said frame data, from said first processing means to said second processing means;
- manufacturing means configured for manufacturing an ophthalmic lens based upon lens data and frame data, wherein said manufacturing means are located at a lens manufacturing side;
- and
- second transmission means configured for transmitting said lens data from said second processing means to said manufacturing means, wherein
- said manufacturing means comprise means configured for recording the holographic mirror by performing holographic recording of a film of unrecorded holographic medium by generating interference between a reference beam and an illumination beam to provide the ophthalmic lens comprising the holographic mirror, wherein
- the holographic recording is performed in an optical arrangement that takes into account at least the configuration of the frame, such that the illumination beam is configured to differentially record a plurality of areas on the film of unrecorded holographic medium, and wherein
- each area corresponds to equal or distinct values of distance of visualization of said displayed virtual image by the wearer, or corresponds to equal or distinct directions of visualization of said displayed virtual image by the wearer.
A method for providing an ophthalmic lens configured to be fitted onto a frame and worn by a wearer, wherein said ophthalmic lens comprises a holographic mirror and wherein said frame comprises a build-in image source configured for illuminating said holographic mirror to cause, upon reflection onto said holographic mirror, visualization of a virtual image by the wearer, said ophthalmic lens being configured for correcting the wearer's virtual vision, said method comprising:
- providing an ophthalmic lens having a front surface and a rear surface,
- wherein said ophthalmic lens comprises a film of unrecorded holographic medium;
- and
- performing holographic recording of said holographic medium by generating interference between a reference beam and an illumination beam to provide an ophthalmic lens comprising a holographic mirror, wherein the holographic recording is performed in an optical arrangement that takes into account at least the configuration of the frame, wherein
- the optical arrangement is such that:
- (i) the illumination beam is configured to differentially record a plurality of areas on the film of unrecorded holographic medium, wherein each area corresponds to equal or distinct values of distance of visualization of said virtual image by the wearer, or corresponds to equal or distinct directions of visualization of said virtual image by the wearer, and
- (ii) the reference beam simulates the beam of the build-in image source to be used for illuminating said holographic mirror, to cause display of the virtual image to be visualized by the wearer when wearing the frame.
