Sensitive pigmented layer of eye is :

Retina is the innermost thinnest and softest but most complicated tunic of an eyeball. It has two main layers an outer, simple epithelium of cuboidal or low columber and heavily pigmented (melanin contaning) cells and an inner layer. The inner layer in the optic region is thick and highly complex containing light sensitive elements nerve cells and fibres. This is the actual neuro-sensory layer of eye. It consists of outer or peripheral layer of rods and cones, middle layer of bipolar nerve cells and inner or medial layer of large ganglionic nerve cells. The layer of rods and cones conisists of the highly specialized neurosensory cells which are actual light sensitive cells, shaped like rods and cones and placed perpendicularly upon the pigmented epithelium.
