Gunstar BlinderGunstar Blinder These Blinds clip onto your hat and are to either shade you from the sun or cover your non aiming eye while in full draw. Gunstar has the answer for archers who tend to close one eye when they shoot. The Eye Blinder LH attaches to the right side of the brim of a hat of a left handed archer, so it blocks the right eye. The Eye Blinder RH attaches to the left side of the brim of a hat of a right handed archer, so it blocks the left eye.
