Abstract: A deformable membrane assembly comprising a fixed support, a fluid-filled envelope, one wall of which is formed by an elastic membrane that is held under tension around its edge by a flexible membrane supporting member, the supporting member being coupled to the fixed support at a plurality of discrete control points around the supporting member by engaging members for controlling the position of the membrane edge; and an adjuster for adjusting the pressure of the fluid within the envelope to adjust the shape of the membrane; wherein at least three control points are provided that are situated around the membrane edge at spaced locations selected to increase the energy of the lowest order out-of-plane bending mode of the supporting member while allowing the membrane to deform according to one or more selected Zernike polynomials. An article of eyewear comprising such a deformable membrane assembly is also disclosed.

Abstract: A deformable membrane assembly comprises an at least partially flexible fluid-filled envelope, one wall of which is formed by an elastic membrane that is held around its edge by a resiliently bendable supporting ring, a fixed support for the envelope and selectively operable means for causing relative movement between the supporting ring and the support for adjusting the pressure of the fluid in the envelope, thereby to cause the membrane to deform. The bending stiffness of the ring varies round the ring such that upon deformation of the membrane the ring bends variably to control the shape of the membrane to a predefined form. The moving means comprise a plurality of ring-engaging members that are arranged to apply a force to the ring at spaced control points. There are at least three control points, and there is a control point at or proximate each point on the ring where the profile of the ring that is needed to produce the predefined form upon deformation of the membrane exhibits a turning point in the direction of the force applied at the control point between two adjacent points where the profile of the ring exhibits an inflection point or a turning point in the opposite direction.

Abstract: A deformable membrane assembly comprises a deformable membrane (70) in contact with a body of fluid (90) and a selectively operable adjuster for adjusting the pressure of the fluid (90) for causing distension of the membrane (70) in accordance with a predefined form. The membrane is held peripherally by a bendable supporting member (50) that is coupled to a fixed support by at least three engaging members (82) at spaced locations round the supporting member (50). An engaging member (82) is provided at or proximate at least one point round the supporting member (50) where the profile of the supporting member (50) corresponding to the predefined form of the membrane (70) exhibits locally maximum or minimum curvature in the direction of distension of the membrane (70),
