Popularity Of 3D Films Exposes Eye Problems
The popularity of 3D films and television has led to a significant number of people finding undiagnosed sight problems, eye experts say.
Children and adults with less than perfect sight can suffer nausea, blurred vision and dizziness after watching films such as Avatar, Alice in Wonderland or How to Train Your Dragon.
Specialists say that these symptoms can occur when the eyes are slightly misaligned, but the problem can be corrected.
Some manufacturers are selling 3D-capable televisions in time for the start of the Fifa World Cup this week. England’s matches are also due to be shown live in 3D at selected cinemas.
Almost two million people in Britain have eye conditions that could impair “stereoscopic vision” — normal, two-eyed depth perception — making it difficult, or even impossible, for them to experience 3D effects.
John Lee, President of The Royal College of Ophthalmologists, said: “Approximately 2-3 per cent of the population can’t see 3D because of early onset squint, or an eye problem that develops later in life.”
Smita Trivedi, a behavioural optometrist in North London, said: “Some people come out of a screening feeling like they’ve had a visual work-out or motion sickness.”
