Dye Lens i4 / i5 Dyetanium Northern Fire.

The treatment of the i4 mask thermal shields provides UV-A, UV-B, UV-C protection and is optically treated to provide superior optical clarity. The screens are also 4D treated, with anti-fog and anti-scratch treatment for optimal durability. A selected number of screens provides dyetanium ™ treatment to reduce glare and balance light transmission.

Unlike many masks on the market, our screens are not flat plastic tips that are pressed and curved. Instead, we use a proprietary process to thermoform our screens and provide them with perfect optical clarity.
