Goggles are provided having a lens cup with a seal portion extending around its peripheral rear edge. The seal portion is adapted to seal against the face of a wearer of the goggles via a face contact surface. The face contact surface is preformed to follow substantially the contours of the wearer's face around the wearer's eye socket, so that little force between the seal portion and the wearer's face is required to achieve sealing. The face contact surface may be preformed in accordance with the average wearer from a demographic group or preformed bespoke for the wearer.
