Sunglasses Technology

Initially developed for pilots, Bigatmo advanced sunglasses technology works, not just for pilots on the flight deck, but for you when you’re driving, playing sports, or just relaxing on a beach.

Bigatmo is in the vanguard of lens and frame technology.

In the past, there was always a compromise.

You could buy tough sunlenses with poor optical properties, or fragile sunlenses with excellent optical properties.

Finding eyewear that performed well, and had all characteristics we were looking for was just not available. We had tried numerous pairs, but our search was fruitless. We knew that many other people shared the same disappointments and frustrations as us.

We decided to make a difference and push the boundaries of sunglasses technology we set to work.

We drew together a team of designers, optical experts, and specialist manufacturers to work on development. To evaluate our progress, a team of professional airline, display and air-race pilots.

During our three year adventure we made an enormous number of development decisions, each governed by our ultimate objectives; to create the very best sunglasses available; anywhere.

The result – a collection of sunglasses with the most advanced technical specifications on the market, where compromise is out of the question!

NXT®/Trivex® Technology

  • Lightweight

Our patented Next Generation NXT®/Trivex® urethane material forms the core of all Bigatmo sunglasses’ lenses. We chose it because NXT® was formulated in the early 1990s for new generation attack helicopter windshields so it has great impact resistance, it’s lightweight, and has superior optics.

  • Clear

Bigatmo NXT®/Trivex® optical lenses are the next stage in its evolution. They’re formed in glass moulds with long, carefully controlled curing times which produces lenses with very low internal stresses, and improved optical quality.

  • Strong

NXT®/Trivex® is the strongest lens material on the market, passing ANSI’s High-Velocity Impact Test. This is a stringent test where 1/4-inch steel spheres are fired at the lens at a velocity of 150 feet-per-second. If an NXT®/Trivex® lens receives an impact, the material returns to its original shape with virtually no residual distortion.

Three Lens Options

Although NXT®/Trivex® is the lens material used in all Bigatmo sunglasses, we offer three different lens options to suit your lifestyle.

  • Copper/Brown Photochromic Lens

Bigatmo Copper/Brown Alutra lenses deliver a punchy view of the world with excellent vibrant colour acuity and high definition optics. The photochromic core is perfect for when you’re out and about, moving between sun and shade. This lens also allows you to comfortably read instrument panels in high contrast environments, like the flight deck when flying; or the dashboard when driving.

  • Grey High Contrast lens

Bigatmo Grey High Contrast Zeolite lenses use advanced Light Management Technology to enhance colours by filtering out the wavelengths that fall between red, blue and green – the primary colours in which we see. Your eyes receive more specific colour information improving overall image sharpness and clarity.

  • Grey High Contrast Polarized lens

Bigatmo Polarized lenses have the same colour enhancing technology as our Zeolite lenses, together with a polarizing filter which dramatically reduces glare from roads, snow, sea and sand, revealing all kinds of hidden details and textures in High Definition.

Industry Leading Lens Coatings

All of our lenses receive a series of industry leading lens coatings to enhance them further.

  • Omniphobic Coating

An “omniphobic” treatment applied to both sides of the lens is designed to disperse water, sweat, make-up and suntan lotion, so lenses are not only easier to clean; but also stay cleaner for longer.

  • 8-layer anti-reflective coating

An industry leading 8-layer anti-reflective coating is applied to the back of all Bigatmo lenses to prevent irritating reflections and also avert reflected UV from entering the eye.

  • Anti-scratch Quarz® layers

High quality anti-static and anti-scratch Quarz® layers are applied to the raw lens and provide superior scratch resistance which helps to make Bigatmo sunglasses extremely durable and long lasting.

  • Optional cosmetic mirror finish

An optional cosmetic mirror finish that looks great, whilst still allowing the lens to perform as it was designed to.

RX Prescription

Bigatmo sunlens technology, lens material, lens design and finishing technology, combined with the expertise of our finishing lab, enable us to produce outstanding RX prescription sunglasses.

Every pair of our prescription sunglasses starts with a pair of semi-finished lens-blanks. The front surface of the lens-blank is the finished part and carries all the sunlens filter technology in the first 0.9 mm. This ensures that our prescription lenses have the same sun-filters and uniform tint as the Alutra, Zeolite and Zeolite Polarized non-prescription lenses.

Sculpted Titanium Frames

  • Titanium Frame Material

All Bigatmo frames use pure titanium for the rims and for all parts of the sunglasses frame where rigidity is important. We chose titanium because it’s ultra lightweight, very strong, extremely workable, corrosion resistant, hypo-allergenic and has a beautiful natural finish.

  • Springy Temples

Beta-titanium, a titanium alloy, is used primarily for the ‘temples’ of our sunglasses frames because it has very similar properties to pure titanium except that it is springy; and it is these springy properties that apply just enough pressure against the side of the head to keep the frames securely in place.

  • Hand Finished

Every Bigatmo frame is hand polished and hand finished, allowing minuscule differences between them and so making each one unique.

Customised Comfortable Fit

All Bigatmo frames Have

  • Adjustable Nosepads

Soft silicone adjustable nosepads for a customised personal fit.

  • Slim Temples

Bigatmo sunglasses fit neatly to the head because, the temples and ear tips are extremely thin and ergonomically shaped. Made from beta-titanium, they’re tensioned to provide a comfortable and secure fit. The inside of the tips are coated with a special epoxy finish designed to provide grip without pulling hair.

  • Styled Hinges

The hinges of the sunglasses are designed for smooth operation, incorporating stops to prevent the ear tips damaging the lenses.
