Our brain works as a Cyclop

London: Ever wondered how we can see sharp images though a blur is projected in each retina?

This is because when each eye separately has a different level of blur, our brain uses as sharp reference the image projected through the eye with the lesser aberration, reveals new research. In this way, the brain works like a Cyclop - the mythical one-eyed creature. The finding could help to improve the treatment for presbyopia.

The research reveals that despite these blur differences; the perception of each eye separately about the sharper image is the same, regardless of the eye we use to make the test and coincides with the blur image projected through the eye with the lesser aberration.
