All our polycarbonate glasses filter 99.9% of UV A, B or C (130 - 300 nm). Our UV400 glasses filter up to 400 nm.
Special filters can eliminate certain parts of light and a high proportion of the electro-magnetic spectrum (ultraviolet rays, infrared rays…).
Lens marking is composed by 2 numbers (separated in the middle by a "-"):
SYMBOL MEANING - EN166: 1: optical class allowing permanent wear of the spectacles

T: (F - B - A) Mechanical resistance to extreme temperatures -5°C/+55°C. N: Resistance to fogging of lenses. K: Resistance to surface damage by fine particles (anti-scratch).
An alloy is the combination of a metallic element with one or several other chemical elements by melting, with the aim of modifying the mechanical properties of the basic metal. Examples of known alloys: • Cast iron: iron + carbon (between 2,1 and 6,7 % in carbon mass) • Steel: iron + carbon (less than 2,1 % in carbon mass) • Brass: copper + zinc • Bronze: copper + tin
