Eyeball

The eyeball is a miscellaneous item in Fallout: Brotherhood of Steel.

Characteristics
In appearance, it's just an average eyeball. However, this eye once belonged to someone with access the laboratories of the Secret Vault. An extremely useful, albeit gruesome, means of getting past the retinal scanner during the quest Learn Mutant Plans.

Location
Dropped by a super mutant in the Secret Vault Laboratories One, near the Lab Two entrance.
