Scientific Research on Blue Light

We have extensively researched blue and artificial light mitigation.

Our products are evidence-based and align with the latest academic research, ensuring optimal performance.

This page features top independent scientific studies that explain the issues with blue and artificial light exposure and the science behind our products.

Scientific Evidence Suggesting

Artificial Blue Light Can Cause Eye Damage

While healthy exposure to natural blue light during the day offers many benefits, artificial sources of blue light from screens, devices, and LED and fluorescent lighting expose us to unnaturally high levels. Studies clearly show that this excessive exposure can lead to permanent eye damage. Symptoms include sore and dry eyes, eye strain, headaches, and migraines, and can even result in conditions such as macular degeneration.

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"

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

Light causes damage to the retina (phototoxicity) and decreases photoreceptor responses to light. The most harmful component of visible light is the blue wavelength (400–500 nm). Read the entire study here.

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

In recent years, people have become increasingly attentive to light pollution influences on their eyes. In the visible spectrum, short-wave blue light with wavelength between 415 nm and 455 nm is closely related to eye light damage. Read more about this research here.

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." Full study here.

Studies on the Benefits of Blue Blocking Glasses

Blocking nocturnal blue light for insomnia: A randomized controlled trial (2018)

"Our underlying theory is that the reduction in blue-light exposure is the likely mechanism whereby amber lenses, compared to clear lenses, improve sleep in individuals with insomnia symptoms." - Journal of Psychiatric Research

Protective effect of blue-light shield eyewear for adults against light pollution from self-luminous devices used at night (2015) 

Sleep efficacy and sleep latency were significantly superior for wearers of the blue-light shield (P < 0.05 for both), and this group reported greater sleepiness during portable device use compared to those using the control eyewear. Participants rated the blue-light shield as providing acceptable visual quality. Study abstract here.

Amber lenses to block blue light and improve sleep: a randomized trial (2009) 

All light is not equal: blue wavelengths are the most potent portion of the visible electromagnetic spectrum for circadian regulation. Therefore, blocking blue light could create a form of physiologic darkness. At the end of the study, the amber lens group experienced significant (p < .001) improvement in sleep quality relative to the control group and positive affect (p = .005). Mood also improved significantly relative to controls. View abstract here.

Blue blocker glasses impede the capacity of bright light to suppress melatonin production (2006) 

"Blue blockers represent an elegant means to prevent the light-induced melatonin suppression."

“Our data show that, irrespective of gender, orange lens glasses can effectively block the capacity, of a 1-hr light pulse of 1300 lx in the eye, to suppress melatonin production.”
