What are the potential eye hazards at work?

Blood borne pathogens from blood or body fluids

Can you use prescription glasses be used as Safety Glasses?

These two are not the same, safety glasses provide optimal protection for your eyes on your job. Safety glasses are generally made from different materials or different thicknesses in order to withstand the impact of flying objects or hazardous materials.

Prescription lenses in normal glasses have a primary objective to correct vision and provide little to no protection from hazardous materials.
