Safety goggles are used by woodworkers, chemists, and a whole range of other professions. They are used to protect the eye and surrounding area from chemicals, particulate matter, and flying debris. There are a wide range of different strengths from goggles that can withstand bullet impacts to ones that are designed only to block chemicals.
Safety goggles are very specific to the type of work being done whether its welding or hammering nails and cutting wood. They should have an ANSI rating that certifies that can withstand a certain amount of impact. Unless they are used to block vapors and chemicals they often have good ventilation and won’t fog up after long hours of hard work.
Safety goggles used for arc welding block out almost all visible light and also protect the entire face from intense UV light exposure. They are much darker than blowtorching and glass blowing safety goggles which mostly eliminate the red glare as opposed to actually darkening the area. There are goggles that can block laser light, and ones that can increase infrared light to see in the dark.
