UV420

Light is categorized by wavelengths: the shortest is ultraviolet, followed by visible and infrared. In the visible light spectrum, the shortest wavelength and highest energy light falls between 400-420 nm and this light is considered high-energy visible (HEV) light.

Sun, LEDs and digital screens emit at high energy a type of short wavelength light, called “blue light”. In this part of visible spectrum, because the blue light has such high energy it is described to be harmful due its capacity to pass through the cornea and concentrate directly on the retina inducing physical and chemical reactions.

Revolutionary UV420 technology protects the eyes against the types of light that can produce damages by cutting HEV light in the 400-420nm part of the spectrum, in addition to blocking all UV wavelength. UV420 technology is designed for daily lifestyle as it neutralizes completely high energy visible blue-violet light and allows healthy blue-turquoise transmission in order to achieve exceptional clarity and improved contrast for better natural color perception. Studies revealed UV420 technology prevents eyestrain and fatigue and in the same time reduces glare for more comfortable vision.

All these benefits make UV420 technology a premium choice for sake of long-term health of the eyes because it does not compromise quality or protection. Considering UV420 is available in a wide range of products and indexes, this alternative can satisfy patients of all ages: kids, adults and seniors.
