A' had only one good eye. He was employed by 'B' on a work in which some risk to the eye by injury was clear. However, the risk was not so great as to necessitate supply of protective goggles to the workmen with both eyes good. 'B' knew the fact that 'A' had only one good eye but did not supply protective goggles to 'A' because no other workman was supplied with protective goggles. During the course of employment, the good eye of 'A' was injured. 'A' brought an action in tort.
