The light glasses are made with high attention to the protective features and also to the visual aspects. They protect perfectly from the UV radiation without limiting the view at the same time. The profiled temples ensure the comfort of use. The lens is covered with a layer protecting it from scratching in order to ensure comfort while the long-lasting use of the eye protection measure.
Safety and durability
The glasses have a very high F value of the lens’ hardness factor as for the airsoft conditions. It expresses the mechanical durability of the material. In this case we are handling with the low energy hit resistance. The lenses are to withstand an impact of a 6mm 0,86g steel BB pellet that moves with the velocity of 45 m/s. When recounted – this result in the kinetic energy of 0,87 J.
The lens’ optical class is determined on the basis of its optical parameters. The means of eye and face protection are divided into three classes. The 1st optical class lenses are designed to be constantly used ( so these glasses can be also used as sunglasses or every day use protective glasses ) while as the 3rd optical class glasses are designed to be used for a short period of time.
What is the EN166?
The EN166 standard applies for all types of individual eye protection used to protect from all types of dangers that can be met in industries, laboratories, in school buildings, in the do it yourself field and so on where you can hurt your eye or distort the vision – this excludes the nuclear type radiation, X rays, laser emissions and the infrared radiation (IR) that is emitted by low-temperature sources. The specifications of this standard do not apply to the eye protection when other complete standards exists – such as the eye protection against lasers.
