Devices providing adjustable optical power have previously been proposed for use as corrective lenses in prescription eyeglasses. There is disclosed a lens having optical power adjustable by relative lateral translation of two lens elements, the lens comprising: a first lens element sealed to a cover to define a cavity therebetween; a second lens element disposed within the cavity and coupled to an elongate drive element extending laterally from the second lens element, the second lens element being arranged to be driven laterally relative to the first lens element by lateral translation of the elongate drive element to thereby adjust the optical power of the lens, the lens comprising a lateral projection into which the cavity and drive element extend, the lateral projection having there mounted an adjuster for driving lateral translation of the elongate drive element. The lens reduces or prevents the ingress of dirt, moisture, sweat and grease between surfaces of the lens elements. There is also disclosed an eyeglasses frame, such as may be particularly suited to said adjustable power lens.

A telomerization process is used to prepare a reaction product containing a noncyclic hydrocarbonoxy-functional polyorganosiloxane. The process includes heating a composition including (A) a cyclic polyorganosiloxane, (B) a silane, and (C) a Lewis Acid telomerization catalyst. The cyclic polyorganosiloxane has formula [(RSiO)], where subscript n is an integer of 4 or more, and each Ris independently H, a hydrocarbyl group, or a halogenated hydrocarbyl group. The silane has formula RSi(OR), where subscript m is an integer from 1 to 4, each Ris independently H, a hydrocarbyl group, or a halogenated hydrocarbyl group, and each Ris independently a hydrocarbyl group. The telomerization catalyst is a Lewis Acid of formula [M]+[RSO]where M is a metal atom selected from Aluminum (Al), Bismuth (Bi), Cerium (Ce), Chromium (Cr), Iron (Fe), Gallium (Ga), Indium (In), Lanthanum (La), Scandium (Sc), Samarium (Sm), and Ytterbium (Yb); Ris selected from an oxygen atom (O) and CF; and x represents a number up to a maximum valence of the metal atom selected for M.

A method of making a lens having adjustable optical power is disclosed. The lens is adjustable by relative lateral translation of at least two lens elements. The method may comprise providing a function yielding optical properties of the lens from starting geometries for the lens elements; refining the function to approximate required gaze angle optical performance over a range of said lateral translation; and using the refined function to derive geometries for making the lens elements. The function may comprise first and second functional parts respectively for the lens elements, and the method comprises using the function to derive geometries for making the lens elements, wherein the function relates optical path difference to a position across the lens elements, and the rate of change of curvature of the first functional part with position is different to the rate of change of curvature of the second functional part with position. There is also disclosed a lens having adjustable optical power. The lens is adjustable by relative lateral translation of at least two lens elements. The adjustable lens may be used for corrective eyeglasses.

The present disclosure provides a sealing device for use in variable focus lenses that includes a guide member having at least one internal cavity and a passageway intersecting the internal cavity. A pinch member is slidably engaged within the internal cavity of the guide member and a portion of the pinch member slides across the passageway and into a portion of the internal cavity to deform and seal a fluid tube extending through the passageway. A set of adjustable eyeglasses employing the sealing device is also provided.

Eyeglasses which comprise a pair of optical plates for each eye. Each of the optical plates is made up of a front plate and a rear plate and a return and hinge mechanism links the optical plates of each pair with one another. An adjustment mechanism facilitates relative movement of the optical plates, of each pair, in a plane substantially perpendicular to a viewing direction of the eyeglasses. The return and hinge mechanism and the adjustment mechanism are decoupled.
