"Unsure as to how fast it regenerates, but as Cameron says, it's much faster than normal Human regeneration. For a specific time? We don't know."

"1) It's assumable that the regrowth takes a matter of days. Mind you that most episodes are probably several days appart atleast. The Connors still sleep, eat, train and shop most of the week. ;)

2) Since skin grafts onto itself closing wounds, thus connecting veins, it's assumable that the veins are connected to the eyes also by regrowth, thus feeding the eyes with the fluids needed for them to stay 'healthy'."

"Okay, here's another question that had me puzzled.
