It's a reflex action. It's automatic, inborn/genetic, and done without thinking.

An organism reacts to a stimulus with a response.
Response. The stimulus is the light.
stimulus
Practically anything can be a stimulus, so organisms can respond to them in just about any way. The definition of 'stimulus' and 'response' are a little paradoxical in this context in that a stimulus is anything that provokes a response and a response is anything done to react to a stimulus. Perhaps some examples will make it clearer: if a predator grasps a lizard's tail (stimulus) it will detach the tail and escape (response). If the weather is excessively hot (stimulus), a plant will close the stomata in its leaves to conserve water (response). If a laboratory mouse notices a new object in its cage (stimulus), it will go investigate it (response).
A reaction is any response to a stimulus. Example:There's a loud noise (Stimulus), the dog turns his head to look for the noise (Response)
Automatic involuntary responses vary depending on the stimulus and the system involved. You need to be more specific.

An automatic response to an environment is known as a reflex. This is a quick, involuntary reaction to a stimulus that helps protect the body from harm. Reflexes are controlled by the spinal cord and do not require conscious thought.
A reflex is an automatic response to a stimulus that may not go all the way to the brain.
An animal's immediate automatic response to an external stimulus will vary depending on the circumstance. When the external environment is stimulated there is a response that is triggered.
Involuntary actions are movements or processes that occur automatically without conscious control, such as heartbeat or digestion. Reflex actions are quick, automatic responses to a stimulus that involve a specific neural pathway, like withdrawing your hand from a hot stove.
An involuntary action is a body process that occurs automatically regardless of external stimulus. In contrast, a reflex is an automated response to an external stimulus.
reflex
A quick involuntary response to a sensory stimulus (e-g knee-jerk) is called
Tropism: An involuntary orienting response; positive or negative reaction to a stimulus source. An example would be the involuntary movement of a plant towards sunlight.
Classical Conditioning?
A reflex is an involuntary response to an external stimulus, usually to protect the body. A reflex is much faster...
