Bigatmo Tropo feature advanced Alutra (copper/brown) P20 photochromic lenses which have been developed using pilot feedback and thousands of hours of in-flight flight deck testing.
- Allow you to read instrumentation in high-contrast environments
- Instantly become darker in bright sunlight and lighter in shade
- Help your eyes remain relaxed and reduce eye fatigue
- Deliver true colour perception and landmark clarity
- Remain comfortable for many hours whilst wearing a headset
Developed with pilots, for pilots: Bigatmo use flight deck testing and pilot feedback throughout our on-going development process. We produce lenses that take care of problematic high contrast environments allowing your eyes to relax, reducing eye fatigue and remain comfortable for many hours even under a headset.
How do the Bigatmo Alutra (copper/brown) P20 Photochromic lenses work? Bigatmo Alutra (copper/brown) photochromic P20 lenses are optimised for high contrast environments, such as flying and driving, where it can be extremely bright outside but where instrumentation is in deep shade. The photochromic element is activated by UV light and so rarely activates on an airliner flight deck due to the thick windscreens. UV penetration into other cockpits and car interiors depends on the screen material and the sun-lenses will activate and adjust accordingly.
