Consumers using 3D smartphones are in danger of damaging their sight and suffering from headaches, a new study has claimed.
Scientists at the University of California claim that 3D smartphones can cause damage to sight as they put a huge demand on our eyes to focus on the screen and simultaneously adjust to the distance of the content.
Researchers revealed that consumers suffered discomfort when content from 3D mobile phones and other short distance displays appeared in front of the screen rather than behind it.
Professor Martin Banks from the University of California said: ‘The discomfort that occurs when viewing stereo 3D object is a big problem that could limit the use of technology. We hope this can inspire further research in this field.’
These claims come just weeks after the world’s first 3D smartphone, the LG Optimus 3D, was released earlier this month.
The Android-powered LG Optimus 3D features a 3D screen and allow users to capture their own 2D or 3D videos and images and view them on a 4.3-inch WVGA display screen without the need for glasses.
Industry insiders have speculated that these new claims could potentially hinder the sales of the highly-anticipated smartphone as concerns over associated health risks increase.
An LG spokesperson told Mobile: ‘According to the American Optometric Association (AOA), there's no evidence that 3D can cause permanent harm to vision. Nonetheless, LG has implemented a number of measures to remove any potential short-term discomfort and to ensure that LG Optimus 3D users have the best possible experience.
‘The LG Optimus 3D was developed with a crosstalk-free display. This provides bright and flicker-free images and allows users to fully immerse themselves in diverse 3D content. In addition to advice and warnings on start up, the Optimus 3D also has a feature that allows users to adjust 3D depth when enjoying video, images or games. This enables users to alter the display to suit their specific needs and preferences.
‘As with most activities, moderation is important. Although the time limitations should be no different than for viewing 2D content, taking frequent breaks while using 3D for long durations is recommended.’
