Anti-reflective lens and method for treating a lens to reduce light reflections for animals and devices that view through the ultra violet light spectrum

A method for treating a lens to reduce light reflections for animals and devices that view through the ultra violet light spectrum, the method comprising:

• providing a substrate, the substrate being defined by a front surface, a rear surface, and a circumferential edge;
• integrating an invisible dye into the substrate, the dye absorbing at least 97 percent of ultra violet light in the ultra violet light range;
• cleaning the surfaces of the substrate;
• plasma etching, with an ultrasonic etching device, the surfaces of the substrate;
• applying a primer solution to the surfaces of the substrate;
• applying multiple coats of an anti-reflective coating to the surfaces of the substrate by vacuum coating, the anti-reflective coating including at least one of the following:
• an adhesion layer, a low index material comprising SiO2, a high index material comprising ZrO2, and a superhydrophobic layer, the anti-reflective coating being applied in the following sequence:
• applying the adhesion layer;
• applying about 164.53 nm of the low index material;
• applying about 14.16 nm of the high index material;
• applying about 23.5 nm of the low index material;
• applying about 101 nm of the high index material;
• applying about 76.19 nm of the low index material;
• applying the superhydrophobic layer;
• and
• inhibiting light glare and light reflections from the substrate for an animal having tetra-chromatic vision or di-chromatic vision, the inhibition of light glare and light reflections being at an incident angle from 0° to 60° when viewed by the animal.

An anti-reflective lens for reducing light reflections for animals and devices that view through the ultra violet light spectrum, the anti-reflective substrate comprising:

• a substrate defined by a front surface, a rear surface, and a circumferential edge;
• an invisible dye integrated into the substrate, the dye absorbing at least 97 percent of ultra violet light in the ultra violet light range;
• and
• an anti-reflective coating applied in multiple coats to the surfaces of the substrate, the anti-reflective coating including at least one of the following:
• an adhesion layer, a low index material comprising SiO2, a high index material comprising ZrO2, and a superhydrophobic layer,
• whereby the anti-reflective coating configures the surfaces of the substrate to minimize reflection of light in the ultraviolet light range between about 300 to 400 nanometers, whereby the anti-reflective coating configures the surfaces of the substrate to have an internal absorption of at least 97 percent of the ultra violet light range between about 300 to 400 nanometers.
