More than 90,000 eye injuries occur each year in the United States. Many of these could have been prevented with proper protective eyewear. The California Occupational Safety and Health Administration (Cal/OSHA) requires that protective eyewear be worn wherever there is the potential for injury from flying particles, hazardous substances, or dangerous light. The eyewear must meet the standards put forth by the American National Standards Institute (ANSI) in Standard Z87.1-1989. Safety eyewear that meets this standard has “Z87.1” imprinted on the frame or lens. Since eye hazards are common in laboratories and shops, it should be a standard practice to wear eye protection in these areas.
