Definition - What does Safety Eyewear mean?
Safety-eyewear is an item of personal protective equipment (PPE) designed to protect the eyes of the wearer from hard blows or other injuries.

Safeopedia explains Safety Eyewear
The Occupational Safety and Health Administration (OSHA) have set forth standards for the use of safety eyewear and work conditions and activities that require it. There are different varieties of safety eyewear including prescription glasses, tinted or polarized glasses and glasses with built in or attachable side shields. These different varieties may have different safety ratings under OSHA's standards and should be made and selected according to OSHA's design specifications for safety. Employers should issue appropriate eye protection when working in conditions outlined by OSHA that require protective eyewear.
