If you’re looking for proof, a recently leaked document obtained by Gizmodo might have provided us with the closest thing to confirmation to date. The document in question is a report compiled by a Environment Health and Safety contractor for Apple, which was mistakenly sent to hundreds of Apple employees and subsequently fell into the hands of Gizmodo.
The report mentions several incidents that happened at Apple’s campus, one of which reads, “After BT4 user study, user advised study lead, that she experienced discomfort in her eye and said she was able to see the laser flash at several points during the study. Study lead referred her to optometrist and secured prototype unit for analysis.”
Another incident reads, “Employee reported eye pain after working with new prototype, thought it may be associated with use.” This has led to speculation that this mysterious device employees are working on could be the rumored AR glasses. However given its vague language it’s hard to say if it is or if it could be something else entirely, so take it with a grain of salt for now.
