Eyes

Norma stood up, but she did not look at Louis.

"Uncle, who's the person beside you?"

"My friend. He's a doctor."

"Uncle, I'm not ill," Norma said, turning her head away.

Chen Zhao realized that Norma had not been looking at them.

Blind? Chen Zhao looked at Louis in surprise.

Feeling Chen Zhao's stare, Louis nodded gently.

"Ms. Norma, nice to meet you."

"Hello, sir, thank you for coming here, but I don't need a doctor." It was clear that Norma was well-educated.

Chen Zhao realized that Norma's eyes were abnormal.

A normal person's pupils are surrounded by the iris sphincter muscle and the iris dilator muscle.

The pupil is the dark hole at the center of the eye. The iris sphincter muscle is a circular muscle around the pupil whose function is to narrow the pupil.

On the other hand, the iris dilator muscle runs radially to the pupil and can enlarge the pupil.
