A thin film optical lens and method for coating an optical substrate serves to apply alternating layers, with varying thicknesses, of a high index dielectric material and a low index dielectric material on first and second surfaces of an optical substrate. The high and low index dielectric materials are layered through thin film deposition. The low index dielectric material is SiO. The high index dielectric material is ZrOand/or Indium Zinc Oxide. The spectral results from application of high and low index dielectric materials reduce infrared radiation, block HEV light transmission, and reduce backside ultraviolet reflections, while also increasing visible (ultraviolet) light transmission through the optical substrate. Thus, the layering of dielectric materials on the first surface of optical substrate reflects up to 40% of the infrared radiation; and the second surface of optical substrate transmits up to 99% of ultraviolet light in the wavelength range between 300 to 400 nanometers.

Thin film optical lens and method for coating a lens

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.

Method for treating a lens to reduce light reflections for animals and devices that view through the ultra violet light spectrum

A high energy visible (HEV) light absorbing material and application method for an ophthalmic substrate includes deposition of an HEV light absorbing material onto the ophthalmic substrate. The HEV light absorbing material is applied through physical vapor deposition as a thin layer on ophthalmic substrates for flexibility and color adaptation. The HEV light absorbing material includes at least one of: aluminum zinc oxide, indium zinc oxide and gallium zinc oxide with a material commonly used in the design of antireflective absorbing materials. The HEV light absorbing coating is antireflective and transmits up to 98% of light for the rest of spectrum. The HEV light absorbing material allows the ophthalmic substrate to selectively absorb blue light that falls in the wavelength range of about 400 nm to about 460 nm.
