1. 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.
    Abstract:
    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...
