Title: Progressive multifocal ophthalmic lens
Inventor: PEDRONO CLAUDE
IPC: G02C7/06
Filed: 1992-10-26
Abstract: The lens has an aspherical surface (S) having a zone (VL) for far vision, a zone (VP) for near vision, and between these two zones, a zone (VI) for intermediate vision, with a meridian curve (MM') along which the curvature of the surface varies progressively and which is inclined from top to bottom towards the nose side of the lens, at least in the intermediate zone (VI). The portion (DP) of the meridian curve situated in the intermediate and near zones (VI and VP) includes a segment (DC) at an angle  alpha  to the vertical where the value of  alpha  is an increasing function of the power addition A of the lens. In a horizontal and vertical system of coordinates (X'X, Y'Y), a point (C) of the segment (DC) has an ordinate whose value is also an increasing function of the power addition A. At said point (C), the mean sphere value of the surface (S) corresponds to a power addition lying in the range of 0.8 to 0.92 times the nominal power addition A of the lens. <IMAGE>

Title: Light emitting polymers
Inventor: ARTLEY RICHARD JOHN
IPC: C09K11/06
Filed: 1994-02-17
Abstract: Organic materials capable of emitting visible light, particularly blue light, with a high degree of control over the brightness and wavelength, when a voltage potential is applied across them consist of fully conjugated polymeric chains to which sidechains are attached, these sidechains not being directly intermolecularly conjugated to the polymeric chains and containing chemical sequences of the type usually termed liquid crystalline. The sidechains should preferably be oriented parallel to the electrodes used.
