From a reddit comment, so could be lies:

yes...here's an excerpt from the story...

"An Electrician ended up with stars in his eyes after being zapped by 14,000 volts during a serious accident at work. The 42 year-old man from California developed the eye disease cataracts after the high voltage current surged through his body. His shoulder touched a live wire and the current passed through his entire body - including the optic nerve, which connects the eye to the brain. The effect was two bizarre star-shaped electrical burns in his eyes, according to The New England Journal of Medicine. Dr Bobby Korn, an associate professor of clinical ophthalmology at the University of California, San Diego, treated the unnamed patient. Dr Korn told NBC News: "The extreme current and voltage that passed through this important natural wire caused damage to the optic nerve itself." Cataracts is clouding on the lens inside the eye which leads to limited vision and the most common cause of blindness. The electrician's story was published in the January issue of the journal. The accident happened 10 years ago and the patient still has poor vision in both of his eyes."

To go through that with only "poor vision", pretty damn lucky

Who's to say that Ai Hoshino isn't also blind?

So you're assuming he was lucky and survived?
