Blue Blocker Glasses as a Countermeasure for Alerting Effects of Evening Light-Emitting Diode Screen Exposure in Male Teenagers (2014)
Research“We conclude that the use of [blue light-blocking] glasses in male adolescents while sitting in front of an LED screen in the evening can attenuate melatonin suppression and alerting effects before sleep. BB glasses therefore have the potential to acutely impede the negative effects modern lighting imposes on circadian physiology in the evening."

Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor
Research"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."

Even dim light before bedtime may disrupt a preschooler’s sleep (2022)
Research"A new study of preschoolers finds that exposure to even very low intensities of light before bedtime can sharply reduce production of the sleep-promoting hormone melatonin, interfering with sleep. It suggests that young children are highly susceptible to the physiological impacts of light at night and some kids are more sensitive than others."

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)
Research"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"
