摘要： An instrument and method for characterising eye-related optical systems, including the live human eye (18) involves scanning an illuminating light beam (22) from a light source and light detector unit (20) from element to element of a beam deflector array (12) of elements (14) arranged laterally across the optical axis (16) of eye (18). At each successive element (14) the illuminating beam (22) is deflected to form an interrogating beam (24) that is directed into the eye (18) at a peripheral angle that depends upon the lateral location of the deflector element. A return beam (23) is reflected or back-scattered from the cornea (38) and returned via the same deflector element to the light source and detector unit (20). This allows the interrogating beams to be scanned sufficiently rapidly into the eye to greatly reduce the variation of eye fixation and gaze that accompany other methods of measuring peripheral refraction or aberration of a natural eye. In addition to or instead of scanning the illumination beam (22) over each element (14) of the array (12), all or multiple elements (14) of the array (12) can be illuminated simultaneously and the multiple interrogating rays (24) thus generated can be gated by the use of an LCD aperture plate (26). Alternatively, an LCD aperture plate (28) can be interposed between a wide illuminating beam (22) and operated to selectively illuminate the beam deflector.

摘要： A contact lens having near vision and distance vision portions, the lens being movable on the eye between first and second positions, those positions corresponding with aligning the wearer's vision through the near vision and distance vision portions respectively. The lens is positionally stable on the eye in each of the two positions, and requires a force to be applied to the lens to move between the first and second positions. Preferably the lens has a back surface and a front surface, and said back surface has either one or two major back curve zones occupying a major portion of the lens back surface.

摘要： A method or process for providing an anti-myopia lens or treatment for a patient's eye with progressive myopia, which involves (in one form) generating biometric data relating to the central and peripheral refractive errors of the eye, optionally together with data relating to the patient's visual or lifestyle needs and the patient's predisposition to progressive myopia. This data is input to a processor or algorithm that generates a basic lens design, a customised design or a program for reshaping the cornea of the eye. The selected modality is applied to the patient and its suitability is assessed with the result of the assessment feedback to the algorithm to generate a refined output design, which is applied to the patient. The process is repeated at intervals to check continued myopia progression and adjust the design of the selected modality after further measurement.

摘要： An instrument and method is for characterizing the optical properties of an optical system, such as a lens, another optical device or the human eye, over an optical surface of the optical system. In one example, an incident beam is scanned over the surface of a lens to generate an emergent beam that is divided by a beam-splitter into two portions that are directed to respective two-dimensional detector arrays located at different optical distances from the lens. The detector arrays output the lateral coordinates of the points of incidence of the respective emergent beam portions so that the angle of emergent beam with respect to the optical axis or incident beam can be accurately determined. Determining the variation in the angle of the emergent beam over the surface of the lens allows many important optical characteristics of the lens to be characterized and mapped onto to the surface of the lens.
