It is mandatory for every inmate to receive a physical exam before entering a prison in the United States.
I pulled Sang Min's records from Halawa.
He did a short stint in 2008, at which time, his eyesight was 20/20.
However, his most recent exam earlier this year showed his eyesight to be 20/100.
Apparently, Mr. Su was offered spectacles at the time, which he declined.
