Although Liberty Sport sports eyewear is designed to offer the best possible protection during certain sporting activities, there is always the possibility that the wearer may sustain an eye, face, or other injury due to impact or because of the nature of the athletic activity. If the frame incurs an severe impact it must be replaced. If the frame is neglected or misused, or is worn improperly, the degree of eye protection provided may be reduced and may result in permanent eye, face, head, or other injuries. Neither the designer, manufacturer, nor Liberty Sport Inc. claims their sports eyewear is unbreakable or eliminates the possibility of injury.
