When people take their next trip to the cinema, they may be doing themselves more good than they think, according to one vision organisation.
The College of Optometrists has claimed that going to see 3D films may help to identify vision problems in certain people and therefore enable them to seek treatment early, the Daily Mail reported.
Research carried out at the college suggests that people who have difficulty focusing in 3D glasses and view blurred images could have an underlying eyesight problem which requires medical attention.
Alternatively, they may just have poor eyesight which can be treated through wearing contact lenses or glasses.
Susan Blakeney, a spokeswoman from the College of Optometrists in London, told the newspaper that the research could have a major bearing on persuading people to get their eyesight checked out.
"There is no evidence to suggest using 3D technology can damage the eyes. If you can"t see the 3D effect, or feel dizzy, tired or uncomfortable when viewing 3D and have not had this problem investigated before, we recommend an eye examination," she noted.
Ms Blakeney added that, as well as being able to determine whether people"s eyes are healthy, an optometrist may be able to incorporate lenses known as prisms into the glasses to help people view things more comfortably.
In a related article Dr Michael Duenas, associate director for health sciences and policy for the American Optometric Association, told the Associated Press that Nintendo"s 3D handheld console, the 3DS, could be a "godsend" for identifying children aged under six who are in need vision therapy.
