Yeah, i rather hope that's not the case to-but i figure if it was, it should have done it a long, long time ago, when the numerous instances of overwhelming blunt force head trauma occurred, or very shortly thereafter. Can it do that, so long afterward? I know for sure those injuries are a factor, if they effect the eye region muscles, they must effect the eye and vision as well-i know this , due to the problems with glare, and "problems" i guess you would say in the surrounding eye area since.
