PVS14 / PVS31 Eyecup | Comfort & Light Signature Reduction for Night Vision

Eyecups for PVS14 optics play a crucial role in the use of night vision devices. They block lateral light leakage, thus reducing the visible light signature for an external observer and improving the user's stealth in tactical or sensitive environments.

They also contribute to greater user comfort by stabilizing eye positioning, limiting glare, and helping to preserve natural adaptation to darkness. In practice, they improve perceived image quality and reduce eye strain during prolonged use.
