Not like this, there ain't.
Like I said there are a lot of questions but this puts him closer to the scene and sure there are a whole lot of reasons why people get blinded, where you did give some explanations.
Dude, your own quote pointed out that the conjuctivitis need not be explained as caused by combat.
So, that's not exactly new 'evidence.'
At best, it's more wiggle room for people to believe what they want to believe already.
The type of conjunctivitis he had was associated with this type of incident, which earlier researchers did not notice.
But if he'd gotten it in combat, or in any type of service-related event, it would have been brought up when he separated, and he'd have received some sort of compensation for it, nu?
It's not really a winning hand to find that researchers ignored evidence which doesn't really support a claim. Pointing it out is just a louder silence on the claim you're trying to support.
Anyway it sounds like you've come across some interesting people.
It's the bell curve.
If you come across enough people, then there will be bigger numbers at both ends of the curve.
But still, if there are six or twelve ways to cause a type of eye damage, the fact of the damage is not evidence for one of them.
I've seen a lot of people hurt in the service, many of them while the Nation was at war. Not a one of them were in combat at the time.
The fact is that the way the military works, only a very few are actually at the sharp end of the stick and poked into combat.
