Dye Precision i4 Goggle System Thermal Lens - Dyetanium Gold

The Dye Precision i4 features an industry first compound radius lens with thermal technology, giving the player the ultimate vertical/ horizontal peripheral vision. Dye thermal lenses provide the bench mark for anti-fog performance. All Invision lenses provide perfect optical clarity and set the standard for visual performance.

The i4 offers unmatched peripheral vision, more than any other mask system on the market today. This added vision makes movement easier to recognize, providing a distinct tactical advantage for users. In addition the i4 goggle comes standard with HARDCOAT, a scratch resistant coating that protects both sides of the lens against scratches and minor abrasions. The included UV coating also provides exceptional protection from the sun's harmful rays.

It offers a rapid lens change system, allowing lens changes in ten seconds or less. It is as simple as pushing on each interior tab arm and then sliding them forward, instantly freeing the i4 lens for replacement.

The pictures may seem as if the lenses are completely different, but it really depends on the angle of which you look at the lens. It is in fact the same lens.
