Alutra Photochromic Lens (copper/ brown)

High Contrast Photochromic Sun, Sports and Driving Lens.

A crisp and punchy high definition, copper/brown photochromic lens. Enhances true colour, contrast, and depth perception.

Superior visual acuity, colour clarity, lightweight comfort and protection from both impact and damaging sunlight. This lens is a sophisticated sun, sports and driving lens. Tested and trusted by pilots, in challenging high contrast environments where precision and performance matter.

When it comes to sun lens performance, controlling the piercing glare from bright sun-light, is only part of the story. To properly protect your eyes from the damaging elements of the sun you need to be wearing UV protective lenses in all sorts of weather conditions not just strong glare. Be it dull or dazzling light, Alutra adjusts itself to have the perfect tint level for any given situation meaning you are more likely to keep your glasses on and remain protected. Also, the Alutra lens enables clear view of instrument panels in high contrast situations such as the dashboard of a car, just part of the reason it’s such a high performance, driving lens.

The photochromic element keeps everything in a state of equanimity; images sharper, colours more saturated and eyes relaxed so the wearers vision is optimised.

As our test pilots or drivers would testify, Bigatmo’s Alutra Copper P20 Photochromic lenses used in our sunglasses have been optimised for high contrast environments.

The Alutra lenses allow your eyes to relax and focus the vibrant colours whatever the weather.

LMT - (Light Management Technology)

The objective of Light Management Technology is to filter out wavelengths that clutter our vision and this results in bolder colours together with improved contrast and definition.

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, or you can simply appreciate the view in changeable weather.

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.
