Light provides predictive power to an organism. That is, light can provide information about action at a distance, of relevance to the future, if there is a brain to process it. Neurons connect and disconnect via hebbian and anti-hebbian processes in response to the stimulus, so in a way the impact of light energy is structured within a biological substrate.
