This lecture from Alexander Wunsch was presented at the 84th International Conference on Light and Vision of the College of Syntonic Optometry (CSO) in Indianapolis, IN, USA.
In photobiology, the definition of action spectra is a crucial step in understanding the underlying mechanisms. Once the action spectrum is found, it often serves as a guide for phototherapeutic interventions, aiming to match the wavelength as closely as possible. Lasers and LED light sources are on the rise and widely available. Monochromatic light is highly effective - but mother nature´s light sources are differently composed. The presentation discusses the value of diligently combined wavelengths even from opposite regions of the light spectrum for phototherapy, photoprevention and cosmetic use.
Remarks: Some of the topics have been addressed in other presentations provided on my vimeo account. Anyhow, repetitions can help to make things clearer. Or, in Latin words: repetitio est mater studiorum...
