A viewing lens and method for treating lenses to minimize glare and reflections for birds with tetra-chromatic vision. The anti-reflection lens is treated to with a coating on the surface. The coating is configured to enable the lens surface to be less perceptible to a bird with tetra-chromatic vision by reducing reflections therefrom. The lens treatment includes applying an anti-reflective coating in multiple coats. The coats comprise an adhesion composition, a low index composition (such as SiO), a high index composition (such as ZrO), and a superhydrophobic composition that are applied in subsequent layers of varying nanometer thicknesses. The treated lens exhibits minimal reflection properties in the visible range of the electromagnetic spectrum and almost no reflection in the UV-A range. This creates a lens surface that is difficult for birds with tetra-chromatic vision to see a reflection therefrom.

Viewing lens and method for treating lenses to minimize glare and reflections for birds with tetra-chromatic vision

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&#xb0; to 60&#xb0;. The anti-reflective coatings are applied in varying amounts of constituents and thicknesses, consisting of: adhesion layer, low index material (SiO), high index material (ZrO), 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.
