Besides scopes and binoculars, the stretchable Bushwacker™ Optic Covers are also designed to fit a variety of flashlights and round headlamps. The covers employ a simple snap-lock feature providing for dust and watertight integrity and emit a transparent Green, Blue or Red light, each with a particular benefit. The colored cover quickly and quietly flips up to utilize the standard white light. The Bushwacker™ Flashlight Covers in Green reduce the strain and adjustment needed for eyes to focus at night. A perfect example is walking out of a bright house into the yard at night. It takes the eyes a few starry seconds to adjust to the dark. The Green lens offers the same degree of brightness from your flashlight without the strain. Ideal for hunters walking at dusk or dawn, campers, pilots, law enforcement, those digging for night crawlers and stronomers just to name a few.
