Abstract: A data record contains at least the following data values: spatial coordinates of a reference point at each eye of the wearer; a spatial direction vector for specifying a viewing direction of the wearer through the spectacle lens; and a spatial rim curve or edge curve. The data record can be used to produce a spectacle lens. A method and a computer program for generating the data record, and a method for producing the spectacle lens are also disclosed. It is possible to produce the spectacle lens after a single capture of a data record for adapting the spectacle lenses to the wearer of the pair of spectacles and to the spectacle frame selected by the wearer. A different spectacle lens as the spectacle lens originally selected can subsequently be used as the spectacle lens without having to record a further data record for the adaptation for the wearer.

Abstract: A pneumatic tire is described which includes a tread, a carcass and a belt structure interposed between the carcass and the tread. The belt structure includes a first and second working belt, wherein the angle of the working belts range from about 12 degrees to about 35 degrees, wherein the belt structure further includes a low angle belt located radially inward of the working belts. The first working belt is the radially innermost working belt, and is the widest belt. The second working belt is the radially outermost belt. The pneumatic tire may further include a second optional low angle belt, that is located between the first low angle belt and the first working belt.
