A paper published by Clinical and Experimental Optometry this month shows that reading from a smartphone for one hour can cause symptoms of tired, uncomfortable eyes and blurred vision. The research was conducted in 2013 as a Year 5 optometry research project by Ms Rene Cheung and Mr Simon Duong, and supervised by Dr Jennifer Long, Dr Lisa Asper and Ms Rosemary Paynter.
“It’s common to see people holding their smartphones very close to their eyes when they are reading from the display” says Dr Long. “In our study we found that our research subjects held the smartphone closer to their eyes at the end of a 60 minute reading task than when they commenced reading. This was associated with uncomfortable eyes.”
