Plano lenses must fit a worker’s face properly in order to be effective. They should not restrict the normal vision and eye movements of the user and must be reasonably impact protective. It is ideal that these lenses are clear, scratch free, washable and reusable for some time. In the U.S., they should comply with Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI) Z87.1 or equal standards.
