Red-Dot scopes are intended to help you quickly find and aim at your target; the scope indicates your bullet's projected point of impact with an adjustable, red LED light. The light is only visible when you're looking through the scope. The scope is powered by a lithium battery installed on top of the LCD brightness dial. The scopes do not provide magnification, and therefore have no minimum eye-relief distance. The scopes are acceptable for rifles or handguns.
