What is the most sensitive part of the retina
The most light sensitive part of the retina is an area in the centre of the retinal surface which is packed with smaller sized hexagonal cone cells. This part is called the fovea centralis or simply the fovea. This region has the highest concentration of cone cells than anywhere else in the retina, because it is this region which is focussed on a point in the visual field when we have to concentrate on that point.
