摘要： The invention provides a method of moulding a vision correction lens from a transparent resin. The resin is introduced into a mould cavity, the sides of which cavity which correspond to the front and rear surfaces of the lens being formed by two sheets, at least one of which is flexible. The amount of resin in the cavity is adjusted to deform the flexible sheet(s) so that the shape of the lens defined by the sheet(s) will provide a desired power, and the resin is then cured. The sheets can be transparent, and a user can look through them as the amount of resin is adjusted, to ensure that the lens is of the desired power. Further, the amount of resin in the cavity can be adjusted to accommodate changes in the refractive index of the resin as it cures.

摘要： The invention relates to a variable focus lens (10), comprising a rigid ring (22), a flexible membrane (20) attached to the front surface of the ring, a rigid transparent front cover (40), attached to the flexible membrane (50), and a rigid rear cover (20) on the rear surface of the ring (22). A cavity (60) is formed between the flexible membrane (50) and the rear cover (20), and the cavity is filled with a liquid. The amount of liquid in the cavity can be varied to vary the curvature of the flexible membrane and so vary the optical characteristics of the lens. The rear cover can be integral with the ring, or formed separately. Further, a second flexible membrane can be positioned between the rear cover and the ring. The various parts of the lens can be held together by adhesive.

摘要： The invention provides a variable focus lens, comprising a ring with a front surface and a rear surface. A flexible membrane is held between the front surface of the ring and a generally rigid transparent front cover, and a rear cover is attached to the rear surface of the ring (optionally with a second flexible membrane sandwiched between the rear cover and the ring). A cavity is formed between the flexible membrane and the rear cover (or the second flexible membrane) is filled with a liquid, and the amount of fluid in the cavity can be varied to vary the curvature of the flexible membrane and so vary the optical characteristics of the lens. The ring of the lens may be coloured, and may be transparent, translucent or opaque. Alternatively, a decorative cover may be attached to the front of the ring to give the appearance of a frame. The lenses may be used in variable focus spectacles.

摘要： Variable focus optical devices, in particular lenses, can include a cavity at least partially defined by a flexible member (2), which may be retained between engaging portions of a frame member (8) and a ring member (12), such that a peripheral region of the membrane is caused to change direction more than twice. The engaging portions of the ring and frame may be high-friction surfaces. In addition, methods of filling a cavity of a lens with transparent fluid, methods of adjusting the pressure of fluid in the cavity, and methods of sealing such a cavity are described, as well the use of such lenses in adjustable spectacles.

摘要： A near eye display comprising: a display device; and a waveguide; wherein the waveguide comprises an entry diffractive element and an exit diffractive element; wherein the display device is arranged to direct light into the waveguide via the entry diffractive element and wherein the exit diffractive element is arranged to direct light from the waveguide towards a user's eye; wherein the display device is arranged to output images in a repeating sequence of two or more different colours. Providing the images are transmitted in sufficiently quick succession, the brain will not perceive them as separate images, but will instead essentially merge them (as if they were overlaid on top of one another. As the brain is good at pattern recognition, it can compensate for any minor misalignments that occur between the different images. In this way the time-multiplexing approach avoids the need for multiple parallel waveguides for each specific colour or colour band.

摘要： The technology described herein provides a system and method for measuring an amount of virus in a sample to be tested. The system comprises a light emitting diode operable to emit UV light towards a sample to be tested, and a detector operable to detect light from fluorescence events induced in a sample by UV light emitted from the light emitting diode. An amount of virus in the sample is then estimated based on at least the light from fluorescence events that is detected by the detector.
