Fit
Much like ear canals, people have different head/facial shapes and structures. There are thousands of styles and shapes of safety eyewear on the market today- some even with adjustable temples. It is recommended to have a few different styles of eyewear on site that best fit workers with rounder or narrower head and facial features. Shifting of eye protection can alter the coverage of safety glasses or goggles and result in eye injuries- making a secure fit crucial for workers performing dynamic movements.
Frame Linings
Many workers in different industries need eye protection from scratches and impacts along with protection from liquid splashes or airborne particles. Specific to goggles, it is important to un- derstand the difference between direct and indirect ventilation as it relates to liquid protection. Direct-vented goggles help mini- mize fogging and should be used when there is no liquid splash risk. Direct-vented goggles have straight-line perforations that allow direct airflow from the work environment. Indirect-vented goggles help minimize fogging and should be used when there is liquid splash risk. Indirect vented goggles have hooded vents to allow indirect airflow from the work environment.

be a godsend to prevent these particles from obscuring workers’ vi- sion. Employers may want to ensure that these types of glasses have anti-fog lenses, as glasses with foam padding can reduce airflow behind the lenses and cause lens fogging.
Simply put, it is a difficult, yet important task for employers to find a style of safety glass or goggle that closes the gap between protection, performance and comfort for all workers.
