The present invention discloses a vehicle glazing having a sharply curved portion and the method for bending such glazing The sharply curved portion of the glass may extend along the surface of the glass. The sharply curved portion is obtained by locally heating by means of a laser source, heating the portion of the glass to a temperature sufficiently high enough to allow said portion of glass to bend. In preferred embodiments, the sharply curved portion comprises a first bent portion described by a first radius and a second bent portion described by a second radius, wherein the point where the radiuses of the first and second bent portions change their orientation generate an inflection point. The radius of curvature of the first and second bent portions is of less than 150 mm.
