Continuity: During the scene where Streisand sings "Papa, Can You Hear Me?" toward the beginning of the film, Yentl's glasses are laid down in front of her and the style of glasses shown in this scene have modern temple/ear pieces - inappropriate for the time period. However, during other scenes where Yentl takes off or puts on her glasses, the glasses are the old-fashioned, cable-temple/wrap-around-the-ear-style glasses - appropriate for the time-period.
