Visual information is visible because light passes through the cornea and is focused by the lens as an inverted image on the retina (Ellis, 2004). The retina is made up of photoreceptor cells; rods and cones with the greatest density of cones located in the fovea, so vision is sharpest for images and information projected to the fovea (Ellis, 2004). Subsequently, visual information from lateralized foveal stimuli projects to the cerebral hemisphere in the brain. In the brain, the left visual hemifield projects to the right hemisphere and the right visual hemifield projects to the left hemisphere (Lavidor, Ellis, Shillcock, & Bland, 2001). Generally for most individuals (especially right-handed people), visual recognition of words and information is most effective when displayed in the right visual field. However, it is debated whether lateralized foveal information in the left or right visual field is doubly projected to both hemispheres or unilaterally projected to the contralateral hemisphere because the fovea is anatomically divided and there is differential contribution of the two hemiretines. Two theories have been put forward. forward on how visual information is projected to the hemispheres. According to the split fovea theory, hemispheric division of processes occurs up to the point of fixation. When the eyes are fixated on a written word, visual information about letters falling to the left of fixation initially projects to the right cerebral hemisphere, while visual information about letters falling to the right of fixation projects to the left cerebral hemisphere. Foveal processing is divided so precisely at the vertical midline that all letters on either side of fixation project (unilaterally) toward the middle of the paper......occurring in foveal vision away from the line median, regardless of how non-visible or obvious it may be when recognizing visual information. There is an overlap in the center of the fovea where information projects to both hemispheres simultaneously, which is consistent with bilateral theory. On the other hand, split fovea theory is an interesting theory of fixation effects that was inspired by previous research unrelated to split fovea theory and therefore unable to provide appropriate evidence. More recently, the split fovea theory has been based on experiments carried out specifically on its support but in which fixation locations were not monitored and the stimuli went beyond foveal vision. It's good to see that research in this area is starting to improve, but it's hard to be excited about a theory when there is no compelling evidence to support it..
