How the eyes read.

Do you know what your eyes are doing while you are reading? A group of researchers has determined that often, our left eye is not looking at the same printed letter as the right eye!
The team’s results demonstrated that both eyes lock on to the same letter 53% of the time; for 39% of the time they see different letters with uncrossed eyes; and for 8% of the time the eyes are crossing to focus on different letters.
A follow-up experiment with the eye-tracking equipment showed that we only see one clear image when reading because our brain fuses the different images from our eyes together.
I’m impressed that they can actually measure such things, as fast as the reading process goes in most adults. Link -via Reddit
