Photobiology

Photobiology is the scientific study of the interactions of light (technically, non-ionizing radiation) and living organisms. The field includes the study of photosynthesis, photomorphogenesis, visual processing, circadian rhythms, bioluminescence, and ultraviolet radiation effects.

The division between ionizing radiation and nonionizing radiation is typically considered to be 10 eV, the energy required to ionize an oxygen atom.
