Eye and Head Protection
Safety glasses are designed to protect the eyes from harmful influences such as bright light, chemicals, dust, splinters, or weather conditions. They are therefore primarily used in the workplace and in sports. Safety glasses for both purposes are essentially constructed like regular eyeglasses. The most common type is single- or double-lens safety glasses, which, like conventional eyeglasses, are secured over the ears with temples.
Full-view safety glasses offer additional eye protection thanks to a circumferential seal. An adjustable headband ensures a tight fit. So-called clip-on safety glasses are attached to eyeglasses or to single- or double-lens safety glasses. (Wikipedia)
Protecting your eyes while working is crucial. External influences can often cause irreparable damage to your eyesight. This can happen suddenly (e.g., from flying particles) or gradually (for example, due to insufficient protection from UV radiation).
Therefore, all safety glasses must comply with the specific requirements of the European standard EN 166 and be certified accordingly by an independent testing institute. The additional features of safety glasses are often decisive.
The German Social Accident Insurance (DGUV) regulations BGR 192 (Berufsgenossenschaftliche Regeln für Sicherheit und Gesundheit bei der Arbeit) point out that additional factors must also be considered. Classic safety glasses that meet the requirements of DIN EN 166 can offer up to 100% UV protection. Accordingly, damaged glasses or components must be replaced.
Safety glasses are used, for example, in the work environments of natural stone, wood, and metal processing companies, chemical laboratories (where they are also called chemist’s goggles), and medical practices where laser treatments are performed. Safety glasses for the latter work environment are usually made entirely of plastic and have lenses that are sometimes heavily tinted where protection against excessive light or radiation is required. For those who wear prescription glasses, larger safety goggles are available that can be worn over them; otherwise, safety goggles are the same size as regular eyeglasses. When performing electric and oxy-fuel welding, the eyes of the person welding must be protected by safety goggles, as otherwise severe burns to the conjunctiva (known as “arc burn”) can occur.
