The Carson Flashshield Anti-Reflective Device is an optical accessory that minimizes reflection by the objective lenses of a 42 mm binocular. Simply by clipping the reflection shield in front of each objective, the honeycomb-shaped light baffle will reduce light reflecting off the lens. In addition to controlling reflected light that can expose the observer’s location to wildlife, each FlashShield acts as a sun shade that blocks glare and also protects the lens surfaces from scratches and dirt.
