Lens materials
PC - Polycarbonate
Infield polycarbonate (PC) lenses and shields are extremely tough and have a high impact resistance. They are ideally suited for use in safety eyewear. PC lenses and visors are lightweight and, in contrast to glass lenses, are not susceptible to burn marks from hot metal sparks.
AC - Acetate
Infield acetate (AC) lenses and visors are highly flexible thus making them perfect for use in wraparound goggles.
TG - Toughened Glass
Toughened glass lenses are highly resistant to scratching and to damage from chemical splashes. However, toughened glass has a significantly lower impact resistance than polycarbonate.
Lens types
AS - Anti-scratch
A special hard coating that significantly increases the scratch resistance qualities of the lens surfaces. AF/AS - Combined Anti-Fog
Anti-scratch
In certain environments it is essential to use lenses and shields that do not steam up. Infield offer both the PC and AC materials with an anti-fog option. Lenses and shields incorporating the anti-fog option are also anti-static and scratch resistant.
AF/ASD - Dual-coat Anti-fog and Anti-scratch
Dual-coated lenses have an anti-fog coating on the back surface and an anti-scratch coating on the front surface.
WE - Welding Protection
Infield safety eyewear with the WE markings are suitable for use in welding applications. The number following the WE marking (for example WE 5) indicates the grade of infrared filter incorporated. Welding filters also protect your eyes from UV-radiation and glare.
SP - Sun Protection
Infield sunshades have an SP marking. Sun protection lenses and visors must not be used for welding.
UV - Ultraviolet protection
Infield lenses and visors with the UV marking give your eyes 100% protection against harmful UV radiation.
