It’s because of his unique internal cultivation technique. He took that rare ginsaeng when he wasn’t ready and he had a surge in internal energy beyond what he could handle. The golden eyes are proof his energy control is incomplete. And it’s one theory I read but it’s possible he himself doesn’t want to show them either, since he considers himself a genius and all that lol
It been so long since I’ve read this that I don’t remember what happened to his eyes lol
