Lens: Alutra (copper/brown) P20 Photochromic lens
Mirror: Silver Gradient
Model No: 0495
Bigatmo Iono 0495 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.
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.
Bigatmo Alutra (copper/brown) P20 Photochromic lens technology
These lenses have a silver gradient mirror finish. Bigatmo gradient mirrors use a more traditional chromium compound on the top half of the lens to reduce light transmission. This reduces extreme glare from above whist retaining the lens properties below, making them ideal for high contrast environments such as driving or flight deck conditions
