The goggles have a very high lens hardness factor value - F - for airsoft conditions. It expresses the mechanical resistance of the material. In this case, we are dealing with resistance to so-called low-energy impacts. The lenses are designed to withstand the impact of a steel ball with a diameter of 6 mm and a weight of 0.86 g moving at 45 m/s. In conversion, this translates into a kinetic energy of 0.87 J.
The optical class of glazing is determined by its optical performance. Eye and face protection is divided into 3 classes. Glazing in optical class 1 is designed for continuous use (so these glasses can also be used as sunglasses or safety glasses for everyday use), while glazing in class 3 is designed for short-term use.
What is EN166?
The EN166 standard applies to all types of personal eye protection used to protect against the various hazards that may be encountered in industry, laboratories, school buildings, DIY, etc., where damage to the eye, or impairment of vision, may occur, with the exception of radiation of nuclear origin, X-rays, laser emissions and infrared (IR) radiation emitted by low-temperature sources. The specifications of this standard do not apply to eye protection where separate and complete standards exist, such as laser eye protection, sunglasses for general use, etc., provided that these standards refer to this standard. Eye protectors fitted with corrective lenses are not excluded. Tolerances for focusing ability and other characteristics correlated with corrective measures are detailed in ISO/DIS8980-1 and ISO/DIS8980-2.
