Ya. We think we figured out why I got cataracts in that eye at such a young age. When I was about 23 or so I was installing a stereo in my car. Lying under the dash drilling into metal and got a metal sliver in that eye.
Hurt like hell but not until many hours later. Emergency room froze the eye and pulled it out. For months I had a little rust ring on my iris. Doc figures that started the breakdown of the protein in the lens way back then.
