On the last page of the article we have this in the form of expert testimony: "You also have scattering occur which can affect vision performance when you hit like optometric lenses, like glasses, or if it goes into the eye, if you have any cataract or opacities in the lens or in the cornea of the eye itself, which can result in vision performance loss.” Correct me if I'm wrong (and I may be), but ... don't you pretty much need perfect vision to fly[1]? And if so, how is the quoted testimony relevant to this specific case? I accept that it's potentially dangerous and that it should be further studied. But by the pilots' descriptions no more so than oncoming traffic on a dark street. In addition, the only information we had about after effects was anecdotal and seemed to consist of a couple of pilots reporting migraines and tingling. I don't know - when you're throwing someone in jail from 2-14 years, I just think there should be more than a couple of anecdotes to support threat of the action that got you there. 1. after reading further comments, looks like my assumption here is wrong - it's possible to fly with these conditions, presumably vision must be correctable to perfect?
