An optical sight, system, and method for a firearm. The optical sight includes a housing including a base. A first support and a second support extend from the base. A top support extends between the first support and the second support. The top support extends over an optical element and includes a surface adjacent to the optical element. A second cross member defining one or more openings between the first cross member and the first and second supports. An optical element supported by said housing between said first support and said second support. A reticle is displayed on the optical element.

A reticle for an optical gun sight is provided having a plurality of vertical reference lines which extend below a horizontal reference line. The grid pattern of vertical reference lines and horizontal reference lines further provide a pattern of at least five vertical lines which extend below a horizontal reference line to a left side of a vertical center line and a second pattern of at least five reference lines which extend below the horizontal reference line and to a right of a vertical center line.

An anti-reflective lens and method for treating a lens to reduce visible light and ultraviolet light at levels perceptible to the vision system of an animal and a detection device having tetra-chromatic vision or di-chromatic vision. The treatment method produces an optical substrate that is less perceptible to an animal and detection device perceptible to view through the UV light spectrum. The method provides a substrate treated on opposite sides with an anti-reflective coating so that reflections from visible light and UV light are not visible to the animal and detection device, from incident angles between 0 to 60. The anti-reflective coatings are applied in varying amounts of constituents and thicknesses, consisting of: adhesion layer, low index material (SiO.sub.2), high index material (ZrO.sub.2), and superhydrophobic layers. The substrate is initially UV treated, and then coated with the anti-reflective coating to minimize visible light and UV light reflection between 300-400 nanometers.

An aiming device is provided including a body, an illumination device associated with the body and an optical element, where the illumination device is operable to selectively display a dot on the optical element being visible to a user. The optical element can include an upper edge and a lower edge, and the dot can display closer to the upper edge than to the lower edge, in some cases in the upper half or one third of the height of the optical element. The device can include a protective frame to which the optical element is joined, and the optical element upper edge can be unconcealed by any part of the protective frame above the upper edge, falling within an open top span of the frame. The optical element can be removable and replaceable relative to the protective frame, with a retainer plate temporarily securing the element to the frame.
