More and more occupations in the US are placing employees in danger when they have to operate dangerous machinery or materials. For a long time, the US did not have any standards of safety that required companies to ensure that the safety of their employees was not compromised in any way. These employees needed to wear the right kind of personal protective equipment and among other items, OSHA prescription safety glasses
are a necessity. Faced with worrisome statistics, the US Congress in 1970 enacted some safety laws.
