How safe is safe?
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.
