Protective glasses with tinted lenses for sunny days. The nose’s were made of soft rubber while as the temples are made of a material that can be formed and adapted to the shape of the head and the ears. Attractive looks and the renowned and worldwide known brand for reasonable price – these are the main features of this product. The extremely light-weight of 30g is another advantage.
The tinted lenses are covered with the Safeguard layer that prevents the fogging and that has got a good scratch resistance. The whole product meets the EN 166 standard and characterizes itself with the F hardness class.
lenses meet the MIL-PRF-31013 184.108.40.206
and the MIL-V-43511C 3.5.10 military
The glasses come with a soft fabric case and a flexible neck band.
Safety and durability
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 glasses’ lenses meet the MIL-PRF-31013 220.127.116.11 military ballistic standard in accordance to which the round weighting about 0,3758g and moving with the velocity of about 640-660 FPS ( 195-201 m/s ) and which generates the kinetic energy on the level of 7,15 – 7,6J.
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, sunglasses for daily use and so on – under the condition that the standards correspond to the aforementioned standard. The eye protection measures equipped with correction lenses are not excluded from the field of its application. The tolerance of the concentration abilities and other characteristics corresponding with the correction actions are listed in the ISO/DIS8980-1 and in the ISO/DIS8980-2.
