Description

     Bolle Viper Smoke

The protective glasses have got wide profiled
lenses. They guarantee a tridimensional protection thanks to which they protect
the eyes not only from direct hits, but also from ricochets or shrapnel. The lenses
used in these glasses meet the European EN 172 standard thanks to which the
protect 100% from UV  radiation and they
are covered with a layer preventing scratches. Besides the glasses the set also
includes a flexible band that can serve to keep the glasses  your neck.  

    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.
