3bi) The light rays from the object pass through the
conjuctiva, cornea, aqueous humour, lens and
vitreous humour in that order. All these
structures refract the light such that it falls on
the retina. This is called focussing. Maximum
focussing is done by the cornea and the lens.
The light then falls on the retina.
This light is received by the photoreceptors –
rods and cones, on the retina. The absorbed light
activates the pigments present in the rods and
cones. The pigments are present on the
membranes of the vesicles. Thus, the light is
then converted into action potentials in the
membranes of the vesicles. These travel as
nervous impulses through the rod or the cone
cell and reach the synaptic knobs. From here the
impulses are transmitted to the bipolar nerve
cells, then to the ganglions and then to the optic
nerves. Thus the nervous impulses generated in
the retina are carried to the brain by about a
million neurons of the optic nerve. The vision is
controlled by the occipital lobe at the back of
the brain. The information received is processed
and we are able to see the image. The image
formed on the retina is inverted. However, the
brain makes us see the image erect. So, though
the eyes are essential for vision, any damage to
the optic nerves also results in impairment of
