They do and did. only for reading glasses, but that's what he needed. I remember the displays as a youngster only a few years after that Twilight Zone was filmed.

They usually carry reading glasses up to about +3. . . . and up until the 1950s, some even carried some generic distance glasses with minus diopters. If you have more complicated eye sight problems such as astigmatism, then an over-the-counter set of glasses is not going to be much help.
