Night vision headgear: head harness with nightvision scope or red dot riflescope.

Given that the magnification is somewhat lacking, range may be restricted, potentially rendering it difficult to acquire or maintain targets.
You may find that wearing the head harness for long or unaccustomed periods of time slightly uncomfortable.
