This Standard sets down the requirements for non-prescription eye protection.
Section 4 deals with personal eye protectors in industrial settings and gives examples of specific hazards together with recommended eye protection.
Section 7 deals with prescription eye protectors.​
There are four critical elements in compliant prescription eyewear.
1.) Appropriate frame
2.) Appropriate lens material and thickness
3.) Appropriate fitting
4.) Labelling and assuring compliance
Face shields provide further protection and can also be worn over the safety eyewear. ​Prescription safety glasses and non-prescription forms must conform to a higher standard of impact resistance than regular eyeglasses. The best assurance is the use of the Standards Mark. Specific criteria have to be met. Safety glasses can allow air around the eye area instead of a seal against the face to avoid dust and splashes.
