Description

     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.
