If you get a bit of firberglass insulation into your eye, your eye will feel uncomfortable and tear up, then wash out the firberglass insulation. However, sometimes you can't quite get it out by yourself. First of all, do not rub your eye, and do not go poking around in your eye with any kind of sharp tip. See an eye doctor as soon as possible.
well, in my opinion, it is dangerous to have this kind of insulation into your eyes, and in some cases, it may lead to some eye problems, such as pink eyes, blurry vision, for insulation consists some chemicals which will be the irritates for your eyes. At this moment, you should clean your eyes with pure water as soon as possible. And then try to use some cool tea bags under your eyes. Just repeat it. And then it can be fine. Anyway, just be careful about it.
