UK cinemas have banned the use of Google Glass over fears the device could be used to make pirate copies of movies.
Prototypes of the high-tech eyewear became available in Britain last week with a price tag of £1,000.
But Phil Clapp, chief executive of the Cinema Exhibitors' Association, said: "Customers will be requested not to wear these into cinema auditoriums, whether the film is playing or not."
The Vue chain has said cinemagoers will have to remove Google Glass as the lights dim.
The device - which allows the wearer to read emails, take videos, and browse the web via a display fixed over the right eye – launched two years ago in the US.
Theatre companies are also considering how to respond to the likely rise of Google Glass use in the UK.
Andrew Lloyd Webber's Really Useful Group, which runs six London theatres, is currently "evaluating the implications".
Hospitals are also likely to ask visitors to remove Google Glass to protect patient privacy.
A Google spokesman told the Independent: "We recommend any cinemas concerned about Glass to treat the device as they treat similar devices like mobile phones: simply ask wearers to turn it off before the film starts.
"Broadly speaking, we also think it's best to have direct and first-hand experience with Glass before creating policies around it.
"The fact that Glass is worn above the eyes and the screen lights up whenever it's activated makes it a fairly lousy device for recording things secretly."
