PVS-14 Sacrificial Lens
A PVS-14 Sacrificial lens protects any PVS-14 style objective lens from dirt and debris. This sacrificial lens attaches by press fitting around the objective lens. Most night vision systems use PVS-14 objective lenses so these will work with RNVG, DTNVG (non anvis), DTNVS, PVS-14, and any other goggle with PVS-14 objective lenses.
Once a lens is scratched they must be replaced. Sacrificial lenses are a great way to protect your investment from unnecessary damage and prevent unnecessary lens replacement. These are a great option for those who are using night vision in force on force training, air-soft, off-roading, and other uses where debris and foreign objects can damage the objective lens.
