****, it takes less than a second to ruin your life. *

Yep it sure does. My brother in law was pulling a nail out of a stud
during a basement framing project. The nail was overhead and he was
wearing prescription safety glasses with side shields. The nail
flipped off of the claw of his hammer and managed to get between his
eyebrow and the glasses. He too sustained cornea damage. He has
regained much of his sight in that eye but has to take eyedrops
constantly to prevent dryness. Still, lucky if you can call a freak
accident lucky.
