Side Shields for Glasses
Definition - What does Side Shields for Glasses mean?
Side shields are items of personal protective equipment (PPE) that are designed to reduce the chance of unwanted flying debris entering the eye through the gaps on the outermost sides of a pair of glasses. Many safety regulations at various workplaces and environments require the use of side shields for glasses. Some safety glasses have them built in and they can also be bought separately and attached to a normal pair of glasses.
Safeopedia explains Side Shields for Glasses
The Occupational Safety and Health Administration (OSHA) provides established standards for the use of side shields of any variety, including when they are required and what variety is suited to a particular activity or workplace. Varieties that are permanently attached are generally considered a higher safety level than those that are detachable. Added benefits of using side shields include tinted or polarized side shields and permanent eye shields which match sunglasses. These prevent unfiltered light from reaching the eyes from the large side gaps in glasses and thus improve the effect of polarized lenses in glasses or prescription lenses.
