Reflex arch is a neural pathway that do not directly pass into the brain, but synapse in the spinal cord. When bright light is focussed on our eyes, this signal do not directly passes into the brain but synapses in the spinal cord which allows us to respond at a much faster rate and this results in immediate closing of our eyes in respond to bright light.

Answer:
When the bright light is focused on your lights the photoreceptors generate electrical impulses and send it to the sensory neurons
they carry the stimuli to the spinal cord which transports the message to the brain
the brain revert back the message by the motor neurons which contract the Pupil.
The sequence of events which occur is as follows:-
Receptors ->sensory neurons -> brain ->motor neurons ->eye muscles-> pupil
