Luminette: Pioneers
in Light Therapy

Since 2006, Luminette has led the way in portable light therapy. Developed at the University of Liège, our patented glasses offer a proven, wearable solution for boosting energy, mood, and sleep.

Trusted by experts and users in 20+ countries, we make light therapy simple, effective, and part of daily life.

We regularly support scientific studies

4 years of research for an innovation

Luminette came out as a rigorously designed light therapy solution, recognized in 2017 as Most Innovative Mental Health Device of the Year. Its progress was made possible thanks to the involvement of leading professors and professionals:

RETINAL SAFETY

During Light Therapy

This study examined retinal responses in participants using a portable light device over an eight-week period. Retinal function was measured at several points during the study and compared with a placebo (dim red light) condition. Across the study period, no meaningful differences were observed between participants using Luminette® and those using the placebo device.

In an 8-week study, use of a portable light device (Luminette®) was not associated with measurable changes in retinal function, as assessed by electroretinography (ERG), when compared with a placebo device (dim-red light).

Bright Light Boosts Post-Lunch

FOCUS

This study examined how different strategies influenced attention and focus after lunch. Participants either rested, took a short nap, or were exposed to different light conditions before completing attention-based tasks. Compared with control conditions, both short naps and bright light exposure were associated with more consistent post-lunch focus and reduced feelings of fatigue. The light sessions were generally well tolerated.

In a study involving 25 healthy adults, post-lunch exposure to bright light using Luminette® was associated with more stable attention and task-switching performance compared with a dim-light condition. The observations were comparable to those seen after a short nap.

Bright Light Exposure and

MOOD REGULATION

This 10-week study examined how participants with mood variability responded to using Luminette® either in the morning or at midday. Mood-related scores showed positive trends across both timing options. Most participants tolerated the sessions well. A small number experienced temporary mood changes, which improved after adjusting light exposure.

A 10-week randomized, double-blind, dose-escalation Phase I/II study involving 34 participants examined the effects of daily bright light exposure using Luminette® glasses, administered either in the morning or at midday.

Post-Night

SHIFT SLEEPINESS

This exploratory study followed 21 individuals working night shifts, who recorded their perceived sleepiness hourly from 21:00 to 07:30. Participants used either Luminette® or a reference light during a short session between 05:00 and 05:30. Following the light session, in the group who received blue-enriched light, sleepiness displayed a more prolonged reduction.

In a small study of 21 night-shift workers, early-morning use of Luminette® was associated with more sleepiness reduction compared with a red-dim light. Participants also reported high comfort ratings.

Bright Light Support for

POSTPARTUM REST

This study followed 114 postpartum women over six weeks as they monitored their nightly rest and daily well-being. Participants who incorporated Luminette® sessions alongside wellness guidance reported greater improvements in perceived sleep quality compared with those following usual routines. These positive patterns were maintained during the follow-up period, and the sessions were generally well received.

In a six-week three-arm randomised controlled trial study, postpartum women using Luminette® as part of a structured light-dark routine reported positive trends in sleep, morning energy, and overall daily functioning. Participants reported good comfort and acceptance.

Nurse Work-Related

WELL-BEING

This study followed 84 operating-room nurses across two four-week periods: one with Luminette® use and one without light exposure. Perceived stress was assessed before and after each period. Participants reported larger positive changes during the periods that included Luminette® use, and this pattern was consistent across both study phases.

In a crossover study involving 84 operating-room nurses, four weeks that included Luminette® use were associated with more favourable perceived stress scores compared with periods without light exposure.

Acute

SLEEP DEPRIVATION

This study examined how individuals responded to early-morning light exposure after a night without sleep. Participants were exposed to different light conditions at 5:00 a.m., and their levels of sleepiness and other attention related measurements were monitored into the morning. Compared with dim light, both Luminette® and a traditional light box were associated with improved sleepiness and attention during the early morning hours. The light sessions were generally well tolerated by participants.

In a study involving 18 sleep-deprived participants, early-morning light exposure using either Luminette® or a light box was associated with more favourable alertness and attention measures compared with dim light conditions.

ALERTNESS

without stress

This study explored how healthy young adults responded to different types of light exposure during the two hours before bedtime. Participants experienced either a blue-enriched light condition and a lower-intensity red-light condition. Compared with the red-light condition, blue-enriched light was associated with changes in attention-related measurements, and indicators linked to stress and overall comfort remained broadly similar between conditions.

In a study involving 17 healthy young adults, evening exposure to blue-enriched light using a head-mounted device was associated with changes in alertness-related measures compared with a red-light condition. No notable changes in cortisol levels were observed.
