As our test pilots or drivers would testify, Bigatmo Alutra Photochromic lenses have been optimised for high contrast environments.

Unlike conventional sunglasses which simply darken your immediate surroundings, the optimised tint of the Alutra Photochromic allows enough light to pass through so that you can easily read your instruments – even inside a dark cockpit or on a shady car dashboard.

Bigatmo Photochromic lenses are perfect for high contrast situations

However, as soon as you step outside into bright sunlight, Bigatmo Alutra Photochromic lenses instantly react to the increase in UV light. Whereas the tint of the lens remains lighter in the shade or when behind a windscreen, it becomes much darker when exposed to direct sunlight.

Following thousands of hours of real time testing and development, Bigatmo Alutra Photochromic lenses have evolved into something quite unique: a high speed lens that reacts so rapidly to changing light conditions that they’re amongst the fastest on the market. This allows your eyes to feel permanently relaxed, and as the photochromic material is integrated into the core of the NXT® lens, it can’t wear off.
