Corrected entry: At approximately one hour into the film, Gandhi is shown wearing wire rimmed glasses with round lenses. At approximately the two hour point, the lenses now have a bi-focal segment that is a half circle in the lower section of the round lens. The addition of bi-focal lenses is consistent with the aging process, since the eyes can no longer focus on nearby objects. With bi-focal lenses, the lower portion of the lens is used for reading and the upper portion of the lens is used for distance. However, in subsequent scenes, Gandhi's glasses sometimes have the bi-focal lenses and sometimes they do not. His glasses alternate between bi-focal and regular lenses approximately seven times throughout the rest of the film. At the end, he is wearing black rimmed glasses without bi-focal lenses.

Correction: My mother has two pairs of glasses - one bifocal, one regular. It is possible to have two sets and use them for different times.
