The bulletproof, 2.7mm thick, optically correct lens is a key feature of each option, providing a remarkable level of protection. It’s CE certified and meets with military ballistic impact standard MIL-DTL-43511D. The lens offers a 170-degree field of view and has a permanent antifog element built into the lens polymer. Lenses can be changed quickly and easily by unlatching the clips on either side, and the Iriz and standard can be fit to hold the roll-off system. If you prefer tear offs, the lens comes with mounts for those and a pack of tear offs at purchase.
