I.S.S.F. eye shield flip-up - white with crossbar clamp 367 is for your non-aiming eye. This fits on any current Champion Shooting glasses frames. You can leave the gray panel up so that you get maximum light to your eye while not seeing anything through the diffused panel; or you can swing the gray panel down for complete occlusion.
