My friend heard that reading while lying down is more strenuous (unhealthy) for eyes.
I like reading in bed (books, tablet). Is there some study that confirms this hypothesis?
I use two positions (looking to the book on the side or looking to the ceiling having the book in iron stand).
There seem to be a few factors that act
- Light intensity and color
- Light direction
- Distance of the book
- Material of the reading item (book, tablet, laptop)
- Position (on side, on back) and gravitation forcing on the liquid in the eye
Let's say we will define ideal conditions for points 1, 2, 3, 4. What interests me most is if the point 5 will cause something bad, if it's worse than reading while sitting or standing
