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.

A sighting device is provided, configured to aim at a target, including a main body, a lens module, a display module, an infrared light assembly, and a filter member. The main body includes a first side and a second side. The lens module is disposed on the first side and has a lens element and an image sensor. The display module is disposed on the second side, connected to the lens module and configured to display an image. The infrared light assembly is disposed on the first side and can be switched between an open state and a closed state. The filter member is disposed between the lens element and the image sensor, and an infrared cutting region thereof is overlapping them or not according to the infrared light assembly in the closed state or the open state.

An improved firearm laser sight comprising a pattern generating element and an enlarging lens for enhanced projection of sight patterns onto an intended target is disclosed. The device is meant to be an accessory for firearms of all types by comprising any standardized methods for attachment, and may serve to decrease the time needed to acquire an intended target before firing. The device may implement a variety of sight patterns that may be projected larger and in a more pronounced way, when compared to standard firearms sights, to provide a clear image that may be quickly acquired even over longer distances. The improved firearm laser sight may be made available with a red or green visible laser, an infrared laser, or an ultraviolet light depending on the intended use of the device.

A tritium housing includes a body extending from a first end to a second end to define a hollow extending therebetween. A lens is disposed adjacent and surrounded by the first end of the body and a sleeve is disposed within said hollow and extends from a closed end disposed adjacent the second end of the housing to an open end disposed adjacent the lens. A tritium vial is disposed within the sleeve to produce illumination visible through the lens. The body is comprised of a colored plastic material for magnifying and brightening the tritium illumination during a daylight use of the tritium housing.
