To be rated as safety glasses, both frame and lenses must adhere to particular ANSI standards. The frames are sturdier than "dress frames," and the lenses must be able to pass a "drop ball" test, which, as the name implies, involves dropping a hard ball onto the lens from a certain height. (Ouch!) If the safety eye glass lens cracks or shatters, it fails the test. A new standard, ANSI Z87.1-2003, was passed recently, which describes requirements for two types of lenses: high impact and basic impact. Employers who require safety eyewear for employees should consult OSHA (Occupational Safety & Health Administration) to help determine which type of lens is more suitable at their job sites.
