Smart phone eye strain

Smart phone eye strain
Research has identified a couple of reasons behind smart phone eye strain. Because of the tiny screens and smaller fonts used on smart phones, the researchers found people generally hold their smart phones closer to their eyes than they would print text. Study results showed people held their phones an average of only 12.6 inches away from their eyes while reading website text and 14 inches when looking at a text message. (The average distance for printed text is nearly 16 inches.) It is noted that font sizes on smart phones were an average of 20% smaller than printed text. In some cases, viewed fonts were 70% smaller. What does this mean for us techno-suckers? Because of the size and distance, our eyes have a harder time focusing on the print. The strain involves two processes accommodation, the adjustment from near to far distance, and vergence, eye movement toward and away from one another.
