    Abstract: A laminated vehicle glazing comprising a first ply of a glazing material and a second ply of a glazing material having a substantially co-extensive ply of an interlayer material laminated there between, at least a portion of the ply of interlayer material having a wedged cross-section, wherein the ply of interlayer material is pre-shaped by stretching such that either: (a) when the wedge angle is calculated at a plurality of points across the glazing, by taking measurements of a deflection of a laser beam as it passes through the glazing, the standard deviation in the magnitude of the wedge angle of the wedged portion is less than 0.05 mrad; or (b) when a grid pattern is projected onto the glazing, the standard deviation in the displacement between observed primary and secondary images of portions of the grid is less than 0.85 mm.
