Protecting horses and other animals from blue light
View Patent ↗Masks and goggles having lens that block blue light from the eyes of animals to provide for better rest and to increase their melatonin levels are disclosed. Methods of using the blue light blocking masks and goggles to block blue light and even longer wavelengths of light are also disclosed.
1 . A method of providing better rest for an equine animal, as indicated by a significant rise in the equine animal's melatonin level, by placing a pair of goggles or a mask on the equine animal and leaving it on the animal during the night, the goggles or mask having lens covering the eyes of the equine animal, the lens blocking at least some visible light waves only having wavelengths from about 400 to about 575 nanometers from reaching the equine animal's eyes.
2 . The method of claim 1 wherein the lens material blocks about forty percent or more of the visible light waves having wavelengths in the range of about 400 to about 525 nanometers.
3 . The method of claim 1 wherein the lens material blocks about one hundred percent of the visible light waves having wavelengths in the range of about 400 nanometers to about 510 nanometers.
4 . The method of claim 1 wherein the lens material blocks about one hundred percent of visible light waves having wavelengths in the range of about 400 nanometers to about 510 nanometers and partially blocks light waves having wave lengths up to about 575 nanometers.
5 . The method of claim 4 wherein the equine animal is a horse.
