The light that filters in the human eye is divided into visible spectrum, in wavelengths between 380 and 780 nm, and non-visible spectrum, which includes light in the ultraviolet (UV light) field and in the infrared field (IR light). The blue light component between 380 and 500 nm is also known as High-Energy Visible light (HEV). HEV light lenses create a “feel” due to the effect of the elements and oxides used in the colour dyes and coatings. This treatment stimulates the receptor cells on the retina creating a brain experience sensation from each specific lens colour. Colours are seen as “pop” thus making the perfect solution for any particular lifestyle. Red, green, and yellow colours seep in resulting in improved contrast, a better separation of colours, and a higher sense of depth. The results are faster reactions and better performances.
The RWX by NXT ® lens has got both high-tech and fashion features. Powered by the state-of-the-art
photochromic technology, it provides the right level of protection when needed as it adapts instantly to the
light environment. From bright sun to sunset, the lens protects your eyes from 100% of the UV rays. The
photochromic molecules are directly embedded in the mass of the polymer and confined close to the front
surface. Therefore, it guarantees durably optimal photochromic control. In particular, the RWX by NXT ® lens
includes fast kinetics such as activation and fading speed. RWX by NXT ® lens is versatile with its large photo
range: version smoke with blue mirrored treatment goes from category 1, when not activated, in
environments and weather conditions with low light, to category 3, when activated, in bright conditions.
Specially designed for the high mountains, the RWX by NXT® lens on an amber base with red mirror goes
from category 2, when not activated, in the presence of lower light conditions, to category 4, if activated, in
the presence of strong conditions brightness.
In addition to its technical features, the RWX by NXT ® lens will also magnify your look! Note that this mirror
coatings contribute to protect from glare and reduce eye fatigue. The oleophobic front-side coating
prevents scratches, smudges, fingerprints, dust and water on the external surface of the lens. Thus,
decreasing the discomfort from fog droplets or light rain as the surface is sliding allowing to move forward
in the activity in mixed weather. At last, to keep the lens gloss and neat, it also minimises the risk to
damage the colour coating as cleaning is facilitated.
Photochromic lenses contain substances that are sensitive to UV rays that change their chemical structure based on the intensity of the light. The lens has a light base color that gets darker when sunlight is more intense, to quickly return to its original color when the light fades. This technology allows you to always wear glasses, passing from shaded areas to particularly bright areas and vice versa. The colors available are CRX bronze and smoke (passage from category 1 to 3) available on models 019 - 005; bronze (change of category from 2 to 4) on models 59G-008 - 007 and transparent (change of category from 0 to 2) on model 838.
Human eye cannot separate the horizontal rays from the vertical rays composing the light. Polarized lens contains a special “polarizing filter”, which absorbs the horizontal rays, responsible of glare and image distortions, and keeps the vertical rays only. Polarized lens assures the best vision, the right colours and contrast perception and a bigger comfort, as it absorbs the glares that normally strain the eye.

In addition to that, the Polarflex RWP lens undergoes a "multicoating" treatment on the external surface of the lens which has the purpose of reducing the light blinding of the glaring surfaces (water, snow, and ice) and at the same time enhancing its filtering power.
For best eye protection against optical radiations: our lens IR infrared is available. Optical radiation damages on the eyes are due to their wavelength and power. Radiations are ultraviolet UV light (length: 100-380 nm), visible light (length: 380-780 nm) and infrared IR-A light (length 780 m-1 mm). IR lens totally stops the absorption of UV lights (UV-A, UV-B, and UV-C) cause of several diseases (cataract, retina degeneration, and photokeratoconjunctivitis). It stops blue light absorption (380-550 nm) one of the cause of photoretinitis. It stops the absorption of infrared IR-A rays, which cause heat damage on eyes, cataracts, damages on retina and cornea and keratocongiuntivitis. IR lens guarantees a clear vision and best depth; protection cat. 2.
Quattro lens is developed for the mountain, with top protection cat. 4. The basic colour, a special smoke shade, is developed to reach a relaxing effect with highly reflective surfaces (snow and ice). The front mirroring aims at reducing the glare.
