VIF Two White x Snow Blue

Product detailed description

Material: The lenses are treated with a special hydrophobic filter, which is scratch-resistant and water-repellent, so even in the rain the lenses are perfectly transparent. In addition to all the accessories, this pair of VIF sunglasses contains exclusively a black polarized lens, which reduces unpleasant glare in intense light. The rubber of the nose-piece and temples stay grippy even when wet, so the glasses will stick to your nose during any sports activity, they ensure comfort even when the glasses are worn for a longer period of time and most importantly, during a potential crash.

VIF sunglasses branded as TR90 have a frame made of Grilamid. Grilamid TR90 is very light, flexible and durable and its properties surpass classic polycarbonate or nylon and significantly affects the comfort, safety and durability of the entire glasses. TR90 is a transparent polyamide made of mixtures of various synthetic resins. It is characterized mainly by very low weight, high flexibility and strength. This material is partly used in Formula 1.

Polarized lenses contain a layer of triacetate (TAC), which reduces glare, increases image clarity and increases scratch resistance. TAC lenses are extremely light and also absorb less moisture, thus, the glasses do not fog up.

The photochromic lens with UV400 filter and a light transmittance ranging from S0 - S2 is the ideal choice for sports in variable sun conditions, such as cycling or running in the woods. The photochromic lenses are self-darkening, allowing them to adjust themselves to the surrounding weather within a pre-defined range of solar intensity. NTS (non-temperature-sensitive) technology activates the tint of the glasses according to the intensity of UV radiation, not the ambient temperature. It takes 10-15 seconds to darken the visor, depending on the UV intensity of the location. In the dark it is completely clear, in the light it achieves the colour of classic sunglasses.

TIP: Do you know how to make sure that the glasses really have a polarized filter? If you place two polarized glasses behind each other, it is visible through them as normally, however, if you rotate one 90°, they will become opaque. Crossing both polarized lenses, filters out the vertical and horizontal waves so that no light passes through.

Note: The polarized lens may affect the perception of LCD screens and other displays.
