Provide protections against high-speed impact (120 m/s) at extremes of temperature (55 C and -5 C), penetration, splash of liquids, heat, molten metals and hot solids.
Best optical quality (highest ranking at the tests of spherical refractive power, astigmatic refractive power, prismatic refractive power, and light diffusion).
Protective films on both sides (prevent damages and scratches during transportation).
Aluminum bound (faceshield can be bent/adjusted easily).
Complied with CE EN166, ANSI Z87+, CSA Z94.3
