Bolle Contour Clear glasses

     Bolle Contour Clear glasses

The comfortable light and elegant protection glasses with a metal made frame that is equipped with spring temples and which is finished with a anti-skid rubber layer in the places contacting the body. They protect not only from mechanical injuries and the UV radiation, but also from sudden flame impacts ( up to the temperature of 420 degrees Celsius ). 

     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.

     Optical class

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 1^st 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 3^rd 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.
