FAQs and Pilots’ Questions:
(What is suitable for flying?)
Are photochromic sunlenses suitable for flying?
Yes they are. There is quite a lot of misleading information around relating to old technology photochromic spectacles and the potential problem of moving from a bright environment to a dark one, rendering the wearer unable to see clearly. Bigatmo photochromic lenses are activated by UV – which is largely blocked by the windshields of cars and aircraft – so that in the driving and flying environment the lenses rarely change. Our lenses also have extremely fast reaction times and a carefully controlled range over which they operate. In three years of intensive testing we have not encountered any problems.
Are polarized lenses suitable for flying?
Currently polarized lenses are not recommended for flying. Traditional polarized lenses are poor in the cockpit environment because the stresses in the windscreens are very visible and instrument screens, both LCD and CRT, are visually unstable. A flight deck test programme for Bigatmo polarized lens will be undertaken in due course. Additionally, there are many people who fly aircraft with traditional analogue instruments and open cockpits who may be happily using polarized lenses. If you are let us know. Sea plane pilots should not wear polarized lenses because of the potential loss of visual cues which are used to judge height above the surface.
What lens tints are most suitable for flying?
This issue is often a little emotional and there are some who have extremely strong views. Our sunlens technology is extremely sophisticated and modern sun-filters do much, much more than just darken the image. During our initial lens development program we considered many tints, some of which were considered to be natural aviation lenses, but we discarded all but two. Our Bigatmo Alutra and Zeolite lenses are brimming with technology and have been developed to have exceptional properties but with different personalities. Take a look: lens demo .
Are progressive lenses suitable for flying?
Yes they are. In recent years progressive lens technology has advanced at an incredible pace. Today’s lenses have big ‘sweet spots’ and smooth transition between them. Information on prescription sunglasses for pilots Until recently the prospect of producing accurate prescriptions for wrapped sunlenses would have been out of the question – it was just too complicated – but now thanks to powerful computers and advanced finishing lab machinery this is available to all. In order to make it work for you in the best way possible, you will need to supply your optician with some key information about your work environment (basically you will need to take a few simple measurements). To help you there is a pdf available to download at the bottom of this page.
Progressive lenses don’t suit everyone; please make sure you are comfortable wearing progressive lenses before ordering.
