Safety glasses and goggles have come a long way. They don’t just protect the eyes from flying particles or impact; they also help reduce eye fatigue. Sometimes all you need is a clear lens, but when there are multiple light sources, high light intensity or other hazards then you need a specific lens.
If it’s important to you that workers can see what they are doing, buy the right lenses for the job. If productivity and safety isn’t a big deal, keep doing what you’re doing.
Lenses should also protect against:
Eye protection needs to not only cover eyes, but protect them from projectiles and fragments. ANSI Z87.1 2015+ states that lenses must be a minimum of 2.0 mm with no
maximum thickness limits. These’s also a military ballistics standard MIL-PRF-31013 for spectacles and MIL-DTL-43511D for goggles.
If an employee works with hazardous radiation I the form of welding, lasers, fiber optics, soldering, brazing, ultraviolet or infrared light certain lenses must be used. It’s best to choose a lens that protect against the maximum intensity that a worker may face.
To avoid obscured vision, coatings are often applied to the inside and outside of safety eyewear and that help prevent fogging from both body heat and the environment.
A foam gasket on a pair of safety glasses can provide a better seal that is ideal for non-chemical and dust environments. They prevent debris from entering any gaps in eyewear and provide a more snug fit.
