Why Is It Important to Wear Safety Glasses?

It is important to wear safety glasses around sources that can send debris airborne, to prevent eye injury. Eye-damaging particulate matter can be seemingly benign or large, hot- and sharp.

Anything people work with that sends chemicals or physical debris into the air, or that has the potential to send debris into the air, puts people's eyes at risk. This is why most factories and medical facilities require workers to wear eye protection. For an example of chemicals, a spilled bucket of acetone can splash chemicals into the air, and into unprotected eyes. For a physical debris example, a sewing machine operator who is sewing quickly can hit a thick spot in fabric, shattering the needle and sending sharp bits into the air and into unprotected eyes.
