Does Reading in Dim Light Really Hurt Your Eyes?

It’s the age-old question: Does reading in dim light really hurt your eyes? Contrary to popular belief, there is no evidence to support that reading in the dark causes any long-term damage to the eyes, according to Jim Sheedy, a doctor of vision science and director of the Vision Performance Institute at Oregon’s Pacific University.

Dr. Sheedy also goes on to say that even though reading in dim light can’t cause any long-term damage to the physiology of your eyes, it may cause fatigue or discomfort. When you read in the dark, your pupils dilate due to the lack of available light, which results in a smaller depth of field. Because your eyes are working harder to change focus, reading in the dark will most likely make your eyes feel fatigued.

It turns out that it may have been an old wise tale, a ploy used by moms to get their children to go to sleep at a reasonable hour.

How Does Reading on a Tablet in the Dark Affect Your Eyesight?

Nowadays, it seems like a lot of people prefer ebooks over traditional paperbacks. So, how does reading a tablet in the dark compare to reading the printed word? According to Dr. Sheedy, it won’t damage your eyes. In fact, pixel density and screen resolution on tablets has reached a point to where the eye actually doesn’t know if it is reading a tablet or paperback.
