When these people read using the modified formatting, their reading instantly improved.' Schneps, who was the lead author on the paper, said, 'What made the difference was the ability of the device to display lines of text that were extremely short (about two or three words per line), as well as its ability to space out the text. The study found that people with dyslexia read more effectively, and with greater ease, when using the e-reader compared with reading on paper.

A 2013 study in the journal PLOS One observed reading comprehension and speed in 103 high school students with dyslexia. Individuals with poor eyesight or reading disorders like dyslexia can benefit more from e-books because they provide a range of options for changing the text size and spacing of lines. E-books also impaired alertness the following day. 'Artificial light exposure from light-emitting e-readers may interfere with users' ability to sleep, ultimately leading to adverse impacts on health.'Ī 2014 study published in the journal PNAS found that reading an e-book before bedtime decreased the production of melatonin, a hormone that preps the body for sleep. Merga, a reading and education specialist in Australia, told CBS News in an email.

There are also potential considerations for those reading e-books on light-emitting e-readers at night (although a number of e-readers do not use light-emitting screens), Dr. High levels of screen luminance from an electronic device can contribute to visual fatigue, a condition marked by tired, itching, burning eyes. Paper suits readers with sleep problems and eye strain Perhaps this somehow aids the reader, providing more fixity and solidity to the reader's sense of unfolding and progress of the text, and hence the story.' 'When you read on paper you can sense with your fingers a pile of pages on the left growing, and shrinking on the right,' the lead researcher, Anne Mangen, of Norway's Stavanger University, told the Guardian. The Guardian reported on an experiment from Norway where people were given a short story to read either on a Kindle or in a paperback book when they were quizzed later, those who read the paperback were more likely to remember plot points in the right order. Several small studies suggest that reading on paper instead of an electronic screen is better for memory retention and focus.
