⚡ At a Glance
- • Wearing Comfort: Soft rubber construction cushions the eye socket and helps reduce pressure during long sessions
- • Best for: Field observers and night-vision operators using PVS-14 or PVS-18 gear who need improved comfort
- • Not ideal for: Users requiring compatibility beyond PVS-14 and PVS-18 night-vision systems
Soft rubber construction and a durable snap ring allow easy fitting and removal. Designed to prevent light intrusion while remaining usable on either eye.
Reduced eye fatigue – thanks to soft rubber construction
Soft rubber forms a flexible seal around the orbital area, conforming to facial contours and cushioning contact points. The material reduces local pressure while maintaining a close fit to the housing.
Less pressure on the brow and cheekbone makes longer observation periods more comfortable and reduces the need for frequent breaks.
Secure, repeatable fit – with a durable snap ring
A durable snap ring attaches the eyecup to the mounting flange, locking the eyecup in place for consistent alignment. The ring design allows quick attachment and removal without tools.
Consistent alignment between uses reduces setup time and keeps the seal reliable during field swaps or maintenance checks.
Ambidextrous use – with reversible fit for left or right eyes
Symmetrical eyecup geometry and an open mounting interface permit positioning for either eye without modification. No handed alteration is required to switch sides.
Operators can change viewing sides quickly, useful when sharing kit or alternating posture during extended watches.
