EyeKon’s Natural Yellow Lenses For Optimal UV Protection
Yellow lenses are UVA blocking and violet light filtering! These intraocular lenses use
2-HydroxyKynurenine for hydrophilic IOL’s and
4-Phenyldiazenyl Phenyl Methacrylate for hydrophobic IOL’s, having the same light spectrum. This is the way Mother Nature designed our natural lens. It blocks UVA and filters out the harmful violet rays, while still allowing some beneficial violet rays to enter.
What are Intraocular Lenses?
An Intraocular lens (IOL) is a biocompatible material that is surgically implanted to replace or supplement the eye’s natural crystalline lens. They have been used in the United States since the late 1960s to restore vision to cataract patients, and more recently are being used in several types of refractive eye surgery. To understand how an intraocular lens works, you need to understand how the eye’s natural lenses function.
The eye works like a camera with two lenses. One lens is the cornea, a clear membrane that covers the front of the eye. The other lens is the eye’s natural crystalline lens, which is located behind the pupil. The cornea is responsible for about 70 percent of the eye’s focusing power, while the natural lens “fine-tunes” the image before it is focused on the retina at the back of the eye. The retina works like the film in a camera, receiving light images and sending them through the optic nerve to the brain. If both lenses are working properly, the image is focused precisely on the surface of the retina, and the result is perfect “20/20” vision.
What is a Cataract?
A cataract is a clouding of a part of the eye known as the crystalline lens. This is a clear tissue located behind the pupil – the dark circular opening in the middle of the iris or colored part of the eye. It works with the transparent cornea, which covers the eye’s surface, to focus light on the retina at the back of the eye. When this lens becomes cloudy, or cataractous, light cannot pass to the retina properly, and vision is blurred and decreased. Surgery to remove the diseased lens is the only effective treatment for a cataract. Neither diet nor medications have been shown to stop cataract formation. Cataract surgery is now a frequently performed operation in most parts of the world. More than one million cataract procedures are performed every year, and in the majority of those cases, the diseased tissue is replaced with artificial devices known as IOL’s.
