Abstract: The present disclosure provides for a system and method for remote image projection. The system may comprise a compact optical system to provide remote projections of images. The system may comprise an image correction subsystem, an image motion and positioning subsystem, an image relay and deflection subsystem, a source image, a warped image, a remotely projected image. The method may comprise processing the source image with a dewarping algorithm. The image correction subsystem may comprise a source image, a dewarping algorithm. When the system comprises an intermediate image plane, the warped image may be configured to project on the target projection surface upon arrival to the intermediate image plane. The image relay and deflection subsystem may comprise passive mechanical relay optics to refine the remotely projected image and direct the remotely projected image to the target projection surface.

Abstract: The system and methods are made to apply interferometry to ophthalmic applications. The system makes use of a low-coherence interferometer to obtain a plurality of measurements of a contacts lens. The system and methods characterizes the surface profile of both surfaces of a contact lens, a thickness profiles, and combines these measurements with an index information to reconstruct a complete model of the contact lens.

Abstract: An ophthalmic lens incorporating a usage compliance indicator may be utilized to indicate when the lens should be discarded or otherwise treated. The usage compliance indicator comprises a material that is clear when the lens is removed from its packaging and transforms to a visible marking over a given period of time corresponding to the manufacturer's suggested usable time. The material is compatible with the lens material and does not interfere with the optics.

Abstract: An ophthalmic lens incorporating clearly identifiable, highly visible inversion marking(s) that become invisible when placed on the eye may be utilized to allow an individual to easily distinguish between the normal state of the lens and the inverted state of the lens. The ophthalmic lens comprises a thin material layer capable of changing its optical state from diffusive light scattering, colored, or both, to invisible transparent at the corneal temperature of a normal person, at the influence of ambient light, or a combination thereof.

Abstract: Modified MZ (Mach-Zender) interferometers are utilized to analyze the transmitted, aspherical wavefront of an ophthalmic lens by mounting the lens in a cuvette having a rotatable carousel that can hold multiple lenses. Fresh, temperature controlled, saline solution is circulated about the lenses, and the cuvette is positioned in a vertical test arm of the interferometer configuration. Reverse raytracing is utilized to remove aberrations induced into the wavefront as it is imaged from immediately behind the lens to the detector of the interferometer.
