It implies that the lenses of safety glasses must pass a drop ball test, in which a ball is dropped on the lens to test whether it is hard enough to withstand all kinds of accidental assaults. The lenses are most commonly made of virgin resin polycarbonate which is stronger than regular lenses. The light weight and impact-resistant lenses of the safety glasses come in both prescription and non-prescription forms.

There are mainly two types of lenses: high impact and basic impact. It is the responsibility of the employers who require protective eyewear for their employees to consult OSHA (Occupational Safety & Health Administration) regulations to know which type of safety glass is required at their job sites.
