Abstract: A face protector includes a one piece shield in which an optical center is displaced away from the normal straight ahead line of sight toward an activity specific line of sight to minimize image shift that occurs when a direction of gaze passes across the edge of the shield. An apex of the shield is formed at a forwardmost point of the shield, or a virtual extension of the shield, when the shield is in an as worn position on a wearer. In particular examples, an optical axis extends through the optical center, at a non-zero angle to the normal straight ahead line of sight and substantially parallel to the activity specific line of sight, with the optical center being placed away from the apex. In particular examples, the optical axis is closer to (or coincident with) an activity specific line of sight of one of the right or left eye. The face protector is particularly useful in activities such as sports, for example hockey, football, or baseball which involve activity specific lines of sight.
