Trapped

The first time Lex used the Fancy Monocle, the amount of details it provided were overwhelming. It analyzed the material of each and every item it saw, and started randomly measuring things in detail he found difficult to even imagine ever needing. To be able to keep it at a level where Lex could actually use it, he had to disable many features and keep it limited in what information it provided him. As a result, in the early days, it had even saved his life by detecting the arrival of zombies before he himself was able to see them.
