Ten years of blindness due to psychological factors is indeed quite long.
Ruan Qi looked up in surprise, "Did your friend's younger brother suffer a major psychological shock?"
"Yes." Yu Jin nodded, sighed, "I heard from my friend that his little cousin was abducted ten years ago, and it took a lot of effort to rescue him."
Ruan Qi's expression changed slightly, her hand that was about to close the car door suddenly halted.
Yu Jin didn't notice her change and continued, "That kid became withdrawn for several months after coming back, and when he recovered, he couldn't see anymore. Over the years, he's seen many psychologists, even ophthalmic experts, but all the examinations concluded the same: the psychological stimuli were too strong, causing functional blindness. The psychologist said he might have seen something terrifying after being kidnapped, leading to a subconscious self-defense mechanism, hence the blindness. Teacher Ruan, can you treat this kind of situation?"
