ABSTRACT It has been recently discovered that blue wavelengths form the portion of the visible electromagnetic spectrum that most potently regulates circadian rhythm. We investigated the effect of blue light-blocking glasses in subjects with delayed sleep phase disorder (DSPD). This open-label trial was conducted over 4 consecutive weeks. The DSPD patients were instructed to wear blue light-blocking amber glasses from 21:00 p.m. to bedtime, every evening for 2 weeks. To ascertain the outcome of…

Effect of blue-blocking glasses in major depressive disorder with sleep onset insomnia: A randomized, double-blind, placebo-controlled study
TLDR
It is hypothesized that wearing blue-blocking glasses in the evening may influence circadian rhythm disturbances in patients with major depressive disorder (MDD), resulting in improved sleep and mood and Glasses fitted to individual patients may improve efficacy and safety.
Daily Profiles of Light Exposure and Evening Use of Light-emitting Devices in Young Adults Complaining of a Delayed Sleep Schedule
TLDR
This study suggests that individuals complaining of a delayed sleep schedule engage in light-related behaviors favoring a later circadian phase and a later bedtime.
Evening wear of blue-blocking glasses for sleep and mood disorders: a systematic review
TLDR
There was substantial evidence for blue-blocking glasses being a successful intervention for reducing sleep onset latency in patients with sleep disorders, jet lag, or variable shift work schedules.
Interventions to reduce short-wavelength (“blue”) light exposure at night and their effects on sleep: A systematic review and meta-analysis
TLDR
There is some, albeit mixed, evidence that wearing color-tinted lenses in frames to filter short-wavelength light exposure to the eye before nocturnal sleep can improve sleep, particularly in individuals with insomnia, bipolar disorder, delayed sleep phase syndrome, or attention-deficit hyperactive disorder.
The Clinical Effect of Blue Light Therapy on Patients with Delayed Sleep-Wake Phase Disorder
Objective To investigate the feasibility and patient acceptance of applying blue light glasses to treat delayed sleep-wake phase disorder (DSWPD). Methods Fifteen patients with DSWPD were collected…
Circadian phase, dynamics of subjective sleepiness and sensitivity to blue light in young adults complaining of a delayed sleep schedule.
Long-Term Reduction of Short-Wavelength Light Affects Sustained Attention and Visuospatial Working Memory With No Evidence for a Change in Circadian Rhythmicity
TLDR
Evidence is provided that prolonged reduction of BL exposure directly affects human cognitive functioning regardless of circadian rhythmicity, and both for sustained attention and visuospatial memory.
Optimized office lighting advances melatonin phase and peripheral heat loss prior bedtime
TLDR
Optimized dynamic workplace lighting has the potential to promote earlier melatonin onset and peripheral heat loss prior bedtime, which may be beneficial for persons with a delayed circadian timing system.
Blue light insertion at night is involved in sleep and arousal-promoting response delays and depressive-like emotion in mice
TLDR
The results showed that blue light could induce delays in sleep and arousal-promoting responses, and molecular changes indicated that certain brain regions are involved in blue light-induced response processes.
Strategies to decrease social jetlag: Reducing evening blue light advances sleep and melatonin
TLDR
Findings show that controlling light exposure at home can be effective in advancing melatonin secretion and sleep, thereby helping late chronotypes to better cope with early social schedules.

Amber lenses to block blue light and improve sleep: a randomized trial.
TLDR
Results demonstrated that sleep quality at study outset was poorer in the amber lens than the control group, and at the end of the study, the Amber lens group experienced significant improvement in sleep quality relative to the control groups and positive affect, and Mood improved significantly relative to controls.
Wearing Blue-Blockers in the Morning Could Improve Sleep of Workers on a Permanent Night Schedule: A Pilot Study
TLDR
Blue-blockers seem to improve daytime sleep of permanent night-shift workers, and subjective vigilance generally improved on Fridays in the fall–winter group.
Blue blocker glasses impede the capacity of bright light to suppress melatonin production
TLDR
This hypothesis that cutting the blue portion of the light spectrum with orange lens glasses (blue blockers) would prevent the light‐induced melatonin suppression was tested, a test broadly used as an indirect assessment of the circadian clock sensitivity.
Home Lighting Before Usual Bedtime Impacts Circadian Timing: A Field Study
TLDR
It is demonstrated that the light intensity people can generate at home in the few hours before habitual bedtime can alter circadian timing, and people should reduce their evening light exposure to lessen circadian misalignment.
Blocking low-wavelength light prevents nocturnal melatonin suppression with no adverse effect on performance during simulated shift work.
TLDR
Normalization of endogenous melatonin production while wearing goggles did not impair measures of performance, subjective sleepiness, or alertness, and all subjects demonstrated preserved melatonin levels in filtered light similar to their dim-light secretion profile.
Phase-shifting effects of bright morning light as treatment for delayed sleep phase syndrome.
TLDR
It is found that 2 h of bright light exposure in the morning together with light restriction in the evening successfully phase advanced circadian rhythms of core body temperature and multiple sleep latencies in patients with delayed sleep phase syndrome.
Delayed sleep phase syndrome: A placebo‐controlled cross‐over study on the effects of melatonin administered five hours before the individual dim light melatonin onset
TLDR
The results show that analysis of DLMO of patients suffering from DSPS is important both for diagnosis and therapy, and actigraphy showed a significant advance of sleep onset and polysomnography, a significant decreased sleep latency.
Evening use of light-emitting eReaders negatively affects sleep, circadian timing, and next-morning alertness
TLDR
It is found that the use of portable light-emitting devices immediately before bedtime has biological effects that may perpetuate sleep deficiency and disrupt circadian rhythms, both of which can have adverse impacts on performance, health, and safety.
Sensitivity of the human circadian pacemaker to nocturnal light: melatonin phase resetting and suppression
TLDR
It is demonstrated that humans are highly responsive to the phase‐delaying effects of light during the early biological night and that both the phase resetting response to light and the acute suppressive effect of light on plasma melatonin follow a logistic dose‐response curve, as do many circadian responses to light in mammals.
Light level and duration of exposure determine the impact of self-luminous tablets on melatonin suppression.
