Thanks to the experience of Salice Occhiali and continuous research, Salice products protect the eyes from harmful radiation from the cold and wind. Salice Glasses must have these characteristics, together with a refined aesthetic and an excellent fit.

Light and the human eye

Our eyes are usually able to process a light spectrum between 380 and 780 nanometers, while they cannot perceive light with shorter (UV) and longer (IR infrared) waves, that is, everything that lies below and above the visible light spectrum.

Glasses are not just a simple style accessory but must protect the eyes from harmful short-wave UV radiation, completely invisible to the human eye, as well as allowing us more comfortable vision.

Lens protection factors

Sunglasses are classified according to their ability to absorb light. Some lenses have the ability to vary their absorption capacity depending on the intensity of the light and thus adapt to environments where the brightness can vary very quickly.

Category Tone % Absorption Recommended Use
0 Clear lenses 0-20% Cloudy Days / Night
1 Lightly tinted lenses 20-58% Partly cloudy days / Urban areas
2 Medium shade lenses 59-82% Average sunlight
3 Dark lenses 82-91% High intensity light / Beach / Meadow
4 Very dark lenses 91-98% Very high intensity light / Mountain / Sea

Lenses and their treatments

Salice boasts a very wide range of lenses and technical treatments that adapt to different types of use.

HC – High Contrast Lenses

 

Blue light filter lenses create a “sensation” in the wearer due to the effect of the chemicals and oxides used in the dyes and colored coatings. This treatment stimulates the retinal receptor cells, creating a sensation in the brain for each specific color of the lens. The colors are seen as “pop” and are suitable for all types of sports and non-sports activities. In particular, the colors red, green and yellow are able to filter through the treated lens, creating greater contrast, better separation of visible colors and a greater sense of depth. The result guarantees faster reactions and better performance for those who wear them.

RWX by NXT® Lenses

The RWX by NXT® lens combines high-tech elements with elements of great aesthetic appeal. The RWX by NXT® lens is developed on the basis of the most advanced photochromic technology and provides the right level of protection when needed as it immediately adapts to any light intensity. From bright sunshine to sunset, the lens protects the eyes from 100% of UV rays. The photochromic molecules are directly incorporated into the polymer mass and inserted on the outermost surface of the lens, ensuring long-lasting and optimal photochromic control. In particular, the RWX by NXT® lens ensures fast kinetics both in the activation phase and in the lightening phase. The RWX by NXT® lens is available in the category 1-3 and category 2-4 versions.

The first varies the versatility with the transition from category 1, when not activated, in the presence of lower brightness conditions, to category 3, if activated, in the presence of higher brightness conditions for the smoke version with blue mirroring.

Specially designed for high mountains, the RWX by NXT® 2-4 amber-based lens with red mirroring goes from category 2 in low light conditions to category 4 in high light conditions. In addition to its technical properties, the RWX by NXT® lens also improves the appearance of the wearer! These mirroring treatments help protect against glare, thus reducing eye strain. In addition, the RWX by NXT® lens is subjected to an oleophobic surface treatment that allows dust and water to easily slide off the external surface of the lens and also prevents the formation of scratches, stains and fingerprints.

CRX Photochromic Lenses

CRX photochromic lenses contain UV-sensitive substances that change their chemical structure based on the intensity of the light. The lens has a light base color that darkens when the sunlight is more intense, quickly returning to its original color when the light decreases. This technology allows you to always wear glasses when moving from shaded areas to particularly bright areas and vice versa.

The available colors are:

  • CRX bronze and smoke (category transition from 1 to 3)
  • CRX Bronze (progress from category 2 to 4)
  • CRX transparent (category transition from 0 to 2)

The human eye cannot separate the horizontal and vertical light rays that make up light. Polarized lenses contain a special “polarizing filter” that absorbs horizontal light, responsible for glare and image distortion effects, and lets only vertical light pass through. The use of polarized lenses guarantees optimal vision, correct perception of colors and contrast, and greater comfort thanks to the absorption of reflections that normally tire the eye. In addition, the Polarflex RWP lens undergoes a “multilayer” treatment on the external surface of the lens that has the purpose of reducing reflections from dazzling surfaces (water, snow, and ice) and at the same time increasing the filtering power of the lens.

IR Infrared Lens

For maximum eye protection from optical radiation, the IR infrared technical lens is available. The harmful effects of optical radiation on the eye are determined by their different wavelengths and the resulting energy level. Radiation is divided into ultraviolet UV radiation (length: 100-380 nm), visible radiation (length 380-780 nm) and infrared IR-A (780 nm-1 mm). The IR lens completely blocks the absorption of ultraviolet rays (UV-A, UV-B, UV-C), responsible for pathologies such as cataracts, retinal degeneration and photokeratoconjunctivitis. It also blocks the absorption of blue light (380-550 nm), responsible for photoretinitis. It blocks the absorption of infrared rays (IR-A), which cause thermal damage and induce cataracts, as well as being responsible for corneal and retinal damage, and also protects against dry keratoconjunctivitis. The IR lens guarantees clear vision and maximum depth; cat. 2 of protection.

Lens Four

The Quattro lens is a lens developed for high mountains with the highest protection factor in cat. 4. The base color, a particular shade of smoke, has been developed to obtain a greater relaxing effect in the presence of highly reflective surfaces such as snow and ice. The external mirroring is intended to reduce reflection.
