Smartphones with 3D screens are bad for your sight


A new research has revealed, that working with 3D screens on mobile devices may damage your sight and cause severe discomfort. The most popular devices with 3D screens are the LG Optimus 3D, the Nintendo 3DS and the HTC Evo 3D. The research, posted in Journal of Vision, has analyzed the effect of watching 3D screens on 24 adults. The results showed that when they watched the screen from a close distance, people felt discomfort. They also felt the same way,when watching 3D movies on the big screen. The reason for that is that when we watch something in 3D, we have to adapt to both the distance to the screen and to the distance to the image, which may be positioned in front of or behind the screen.
