The brain and the eye work together to recognize and process visual information. Light enters the eye, where the retina translates the perceived image into nerve signals that are sent, thanks to optical pathways, to the brain. The latter blends the visual stimuli from each eye into a single three-dimensional image.
Therefore, for the correct binocular vision, it is important that both eyes are facing in the same direction.
The process that allows binocular vision begins to develop from the first months of life and, during childhood, the normal alignment of the two eyes allows one to develop good vision. In strabismus, since the eyes are misaligned and not oriented in the same direction, only one eye fixes an object. The risk is that the deviated and unused eye will become lazy due to the onset of amblyopia. In addition to aesthetic damage, therefore, the most serious consequence of strabismus is the loss of vision with both eyes (binocular).
