Title: “It’s All In The Eyes”

Jerry dates a cinephile who only sits in the front row of the cinema.

Elaine suspects that her vision impaired boyfriend cheated on her with her when she had a sore throat.

Kramer applies for “medical grade magnifiers” at a hospital so he can read other people’s newspapers on the subway.

George meets a successful man his age at the same hospital who resembles father. He becomes convinced they were swapped at birth.

Each of them uses “it’s all in the eyes” at one point in the episode to justify/explain what they’re struggling with.
