One of four The Twilight Zone (1959) episodes to include an eye, not a spiral, at the introduction. The other three are Mr. Bevis (1960), A World of His Own (1960), and The Mighty Casey (1960).
Does not have the classic four-note theme at the beginning.
This episode owes a lot to the story "Evening Primrose" by sometime TZ contributor John Collier. Collier's tale appeared as a teleplay several years later on ABC, starring Anthony Perkins.
In 1951, John Collier published "Evening Primrose" a short story in the collection "Fancies and Goodnights", which in 1966 was adapted by ABC. There are great similarities in the plot that address the theme of people who are living mannequins in a parallel dimension in stores.
