Movie bosses have declined to comment on people"s claims that 3D films are leaving them with headaches and visual stress.
According to Optician Online, both 20th Century Fox and Disney will not reveal whether they are considering warning viewers about the side effects of seeing 3D films such as the box office-topping Avatar.
Disney highlighted that all of its 3D films, including Up and Frozen were also available for people to view in 2D if they has any concerns.
Also speaking to the news provider, cinema giant Odeon said it would be happy to exchange tickets to a 3D showing for a 2D one where available, or supply a refund, if people have problems during a 3D viewing.
However, the majority of the population do not appear to be put off 3D films, with James Cameron"s Avatar being named the highest grossing film of all time, toppling the director"s Titanic off the top spot.
