Blue Blocker Glasses as a Countermeasure for Alerting Effects of Evening Light-Emitting Diode Screen Exposure in Male Teenagers (2014)

“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.

Scientific Studies on the Negative Effects of Artificial & Blue Light Exposure on Your Health

This is a group of studies that looking at how more generally blue and artificial light exposure interacts with our biology and is negatively impacting or overall health.

PLOS Biology:

Recommendations for daytime, evening, and nighttime indoor light exposure to best support physiology, sleep, and wakefulness in healthy adults (2022)

"ocular light exposure influences many aspects of human physiology and behaviour, including circadian rhythms, sleep, and alertness (both via circadian system–dependent and circadian system–independent routes), mood, neuroendocrine, and cognitive functions."

Chronobiology International:

Evening light exposure to computer screens disrupts human sleep, biological rhythms, and attention abilities (2017)

"Given the widespread use of electronic devices today, our findings suggest that screen light exposure at evening may have detrimental effects on human health and performance."

Life Sciences:

Association between light at night, melatonin secretion, sleep deprivation, and the internal clock: Health impacts and mechanisms of circadian disruption (2017)

"Exposure to Artificial Light At Night (ALAN) results in a disruption of the circadian system, which is deleterious to health."

"The IARC has classified shift work in group 2A of “probable carcinogens to humans” since “they involve a circadian disorganization.”

Journal of biological rhythms:

Effects of Light on Cognitive Brain Responses Depend on Circadian Phase and Sleep Homeostasis (2011)

"Shorter wavelength light exposure increases ongoing nonvisual cognitive activity in subcortical and cortical brain areas."

Journal of biological rhythms:

Entrainment of the Human Circadian System by Light (2005)

"Entrainment is a fundamental property of circadian systems by which the period of the internal clock is synchronized to the period of the entraining stimuli. An important aspect of entrainment in humans is the maintenance of an appropriate phase relationship between the circadian system, the timing of sleep and wakefulness, and environmental time (a.k.a. the phase angle of entrainment) to maintain wakefulness throughout the day and consolidated sleep at night."

Indoor and Built Environment:

The Impact of Light in Buildings on Human Health (2010)

"Exposure to light can have both positive and negative impacts on human health."

Health Promotion Journal of Australia:

Artificial light at night: a neglected population health concern of the built environment (2014)

"Artificial light at night (ALAN) is mentioned as disturbing sleep."

Science Daily:

Even dim light before bedtime may disrupt a preschooler’s sleep (2022)

"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."

Scientific Evidence Showing How Artificial Blue Light Can Cause Permanent Eye Damage

While getting healthy amounts of natural blue light during the day has many health benefits, being exposed to artificial sources of blue light from screens, devices, and LED and fluorescent lighting exposures us to very high levels of unnatural blue light, which studies clearly show this can lead to permanent eye damage. Symptoms can manifest in the form of sore and dry eyes, eye strain, headaches and migraines, and can even lead to conditions such as macular degeneration.

Let’s take a look at the evidence in the academic literature on what artificial sources of blue light can do to our eyes.

International journal of ophthalmology:

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

"short-wave blue light with wavelength between 415 nm and 455 nm is closely related to eye light damage. This high energy blue light passes through the cornea and lens to the retina causing diseases such as dry eye, cataract, age-related macular degeneration"

"harmful blue light-induced effects on human eyes should not be ignored, blue light can also produce different degree of damage to corneal, crystal lens and retina. Therefore, it is necessary to take appropriate protective measures when using blue light-related products"

Free Radical Biology and Medicine:

Retinal damage induced by commercial light emitting diodes (LEDs) (2015)

"The blue component of LED is the major cause of retinal damage"

"LED light caused a state of suffering of the retina with oxidative damage and retinal injury. We observed a loss of photoreceptors and the activation of caspase-independent apoptosis, necroptosis, and necrosis"

PLOS one:

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"

PLOS one:

Influence of Light Emitting Diode-Derived Blue Light Overexposure on Mouse Ocular Surface (2016)

"Overexposure to blue light with short wavelengths can induce oxidative damage and apoptosis to the cornea, which may manifest as increased ocular surface inflammation and resultant dry eye."

Cell Death Discovery:

Bystander effects elicited by single-cell photo-oxidative blue-light stimulation in retinal pigment epithelium cell networks (2017)

"blue LED light has been shown to induce more damage than white or green light, and induce ROS production and lipid peroxidation in RPE cells, resulting in apoptotic cell death. Finally, intense blue light can cause mitochondrial and nuclear DNA damage."

Scientific Studies on the Negative Effects of Flicker from LED & Florescent Lighting

Its important to look beyond just the high blue light output in our modern lighting, as there are other aspects of it such as flicker which is causing harm to our health. The studies below look at what flicker is and what impacts it is having on our health.

Journal of Clinical and Diagnostic Research:

Light Emitting Diode Lighting Flicker, its Impact on Health and the Need to Minimise it (2019)

"It is seen that with LED sources the severity and range of flicker is relatively very high when compared to conventional lights."

"The various adverse effects of flicker include eye strain, fatigue, headache, migraine, blurred vision as well as photo epilepsy in sensitive individuals"

National Library of Medicine:

The impact of flicker from fluorescent lighting on well-being, performance and physiological arousal (1998)

"The purpose of the study was to compare the impact on subjective well-being, performance and physiological arousal of fluorescent light powered by conventional and high-frequency ballasts."

PLOS One:

Potential Biological and Ecological Effects of Flickering Artificial Light (2014)

"Flickering light has been shown to have detrimental effects in humans and other species."
