Over the last two years, I used the Revision Military SAWFLY Military Eyewear System exclusively for all shooting and they have kept lower velocity bits of shrapnel and other debris from injuring my eyes. Keep in mind that these glasses are not designed, nor will they stop bullets, but they kept stray capsules and the such away from my eyes. Additionally, I have used them as eye protection for other mundane projects like running chainsaws; so, having good eye protection was very important. According to Revision, the lenses offer “flawless optics” and “distortion-free vision.” I do not have the scientific equipment to test these claims, but I can say that none of the lenses introduced any perceptible distortions when I wore them.
The SAWFLY lenses are interchangeable, and easily swap out. I was concerned that by changing lenses, the frame would become loose and the lenses would not be securely held, or I would break them, which was completely unfounded, as the lenses, all of which offer full UV A/B protection and the same level of impact resistance, always seemed very secure. According to the company the eyeweat system exceeds civilian impact standards of ANSI Z87.1-2010 and military standards for spectacles (MIL-PRF-31013, clause 220.127.116.11) and goggles (MIL-DTL-43511D, clause 3.5.10). These full wrap-style (strap can be easily removed) spectacles, offering protection forward and to the sides.
MONS GEARBOX highly recommends the Revision Military SAWFLY Military Eyewear System for virtually any purpose, offering very good protection, not sacrificing optical clarity by wearing them. The ability to swap lenses to meet varied needs is a real bonus. If you want the best in protection for your eyes, give the Revision SAWFLY a look.
