I am an avid bedtime reader, for better or for worse. So this article from the Wall Street Journal, “Does reading in dim light hurt your eyes?” certainly piqued my curiosity. It’s worth a read, if for nothing else than the part about pirates and eye patches.
“Turns out, our parents were wrong. “There is no reason to believe nor evidence to support that any long-term damage to the eyes or change in the physiology to the eyes can be caused by reading in the dark,” Dr. Sheedy says.
… “The predominant determinant of myopia is genetics.” No link to long-term damage has ever been conclusively shown, says Dr. Sheedy. “It’s an old tale, a ploy used by moms to get kids to go to sleep when they wanted them to,” he says.
Reading on a tablet device won’t damage your eyes, Dr. Sheedy says. His team has studied various fonts, computer displays and pixel resolutions, and found the difference in effect on the eye between reading e-ink and the printed word to be negligible.”
Reading in the dark hurts your eyes: more myth than reality? While it likely varies on an individual basis, there might be some science to be said about backlit screens around bedtime, but I much prefer an E-Ink screen for reading in the dark.
And on a related note, check out this neat article from the San Francisco Chronicle: “Reading in the dark – with a headlamp”
“Usually when reading, we may be concentrating on a line or a sentence, but somewhere in the back of our minds, we’re also seeing the larger context, the whole paragraph, the page, and even the next page. We notice whether the paragraphs to come are long, whether we’re at the end of a chapter; sometimes our eyes wander from the sentence to look ahead, reading a few words or a sentence, and then returning to where we were …
The headlamp changed everything. There was nothing but that circle of light that didn’t even cover the whole page, just a small chunk of words. To see the next group of words, I had to move my head slightly or move the book. I was no longer reading in a context, but reading each line as it came into view.”
The immersive aspect of our eyeballs focused on just a circle of words sounds wonderful to me. I kind of want to buy a headlamp now.
