Hidden method of reading revealed
At the BA Festival of Science in York, the researchers also revealed that our brain can fuse two separate images to obtain a clear view of a page. Sophisticated eye-tracking equipment allowed the team to pinpoint which letter a volunteer’s eyes focused on, when reading 14-point font from one metre away.

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.
