ABSTRACT:
An eyeguard for a low light level or night vision rifle sight which does not rely on uniform axial pressure for proper opening comprises a moulded rubber body having a front portion which fits on the viewing end of the sight, a back cup portion angled with respect to the front portion, and a middle thin walled deformable portion to which a single flap is secured. The flap is biased towards a closed position by the resilience of the body but is opened by angular pressure applied by an observer's eye socket to the cup portion.
