Not only blue light - but also green light, affects your melatonin levels

Research have shown, that we must protect ourselves from 400-550nm light wavelengths.

  • Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor

    "Polychromatic action spectra were reasonably consistent in indicating that the spectral region between 400nm and 550nm provides the strongest. stimulation of circadian and neuroendocrine responses."This means is the wavelengths of light between 400 - 550nm should be completely blocked for optimal melatonin secretion after dark."

Unveiling Scientific Proof: The Peril of Permanent Eye Damage Caused by Artificial Blue Light

While incorporating a sufficient amount of natural blue light into our daily routines offers various health benefits, it's crucial to acknowledge the potential risks associated with prolonged exposure to artificial sources of blue light. Screens, devices, and artificial lighting, particularly LED and fluorescent sources, can subject us to heightened levels of unnatural blue light. Scientific studies consistently highlight the potential for permanent eye damage as a consequence of this exposure. Common symptoms include discomfort such as sore and dry eyes, eye strain, headaches, and migraines. Moreover, these effects may escalate to more severe conditions, including the development of macular degeneration.

  • Removal of the blue component of light significantly decreases retinal damage after high intensity exposure (2018)

    "Retinal photodamage caused by a conventional light source (cold) can become chronic if exposure is high and long enough. In contrast, the use of blue-blocking filters can significantly alleviate the functional loss of retinal photosensitive cells. Therefore, these filters might be an effective mechanism to protect us from ocular pathologies"

  • Research progress about the effect and prevention of blue light on eyes (2018)
