I almost lost an eye on 1995 when I was 20 years old. I had a piece of tool steel chip off a die at work and go straight through my pupil.It was almost painless....sorta felt like getting poked in the eye.All this fluid poored down my cheek and it went instantly white.Everyone thinks you would see black..but it was white.I looked in the mirror and my pupil was torn.It looked like a drip of black paint running from the bottom,if that makes sense.It went through the cornea and through the lense and was at the very back of the eye.They had to do a cat scan to find out if it was in the eye or if it had went through it.It destroyed the lense and it had to be removed completely.They replaced it with an artifitial lense about 6 months later.I had to wear a black patch over it during that time because it was very sensitive to light,because the pupil was very large due to the tear created.They closed that up later,but because of that it will not dilate completely..at night it is much smaller than the other one,making it a little hard to see in the dark. I didn't lose it,but 4 surgeries later my vision is 20/80..mostly due to scar tissue on the cornea.I laugh at how many people in my line of work take chances with their eyes...you don't realize how much of a blessing they are until something bad happens. I won't even work in the garage at home without safety glasses..and I sure won't ever take them off at work again.
