There's two tales in which Doc loses his glasses. The first took place "50 years earlier at least" and we get to see what the dwarfs' leader looks like without his spectacles. Dopey helps him find them.
The second story occurs out in the forest. All the dwarfs and animals pitch in this time to locate the missing glasses.
