Lawman (1958)

Season 2: Episode 7

When Beth, a girl who works in the Bird Cage, is murdered, the killer is seen by Oren, an old man with very thick glasses. The glasses are broken as the killer rushes out the door, leaving him dazed and nearly blind. Dan sets a trap, insisting that Oren saw the whole thing and can identify the killer as soon as he gets his new glasses.
