The Science Behind SOMNISE
What is Blue Light?
Blue light (380–500 nm wavelength) is the most potent portion of the visible light spectrum for disrupting sleep. It suppresses melatonin – the hormone that signals your body it's time to sleep – more than any other wavelength.
Modern lifestyles and technology have disrupted the natural signals that once kept our sleep cycles in harmony with the sun. A Harvard study found that just four hours of evening iPad use suppressed melatonin by 55% and shifted the body's internal clock by 1.5 hours.
The circadian connection
Your body runs on an internal 24-hour clock, known as the circadian rhythm. This system evolved over thousands of years to respond to the natural cycle of sunlight during the day and darkness at night.
Light tells your brain when to be alert. Darkness tells your body when to rest.

Melatonin: The sleep hormone
At night, in the absence of blue light, the brain releases melatonin – the hormone that signals it's time to sleep.
Melatonin doesn't just make you tired. It coordinates a whole cascade of nighttime processes: slowing the nervous system, lowering core body temperature, and preparing the brain for restorative sleep.
Today, our evenings are filled with phones, laptops, televisions, and LED lighting – all of which emit blue wavelengths similar to daylight.
To your brain, this light looks like the sun is still up.

How Blue Light Disrupts Your Sleep Cycle
Blue light at night can delay sleep and reduce sleep quality.
Blue Light at Night
Blue light disrupts sleep through a specific chain reaction in your brain.
Light-Sensitive Cells in Your Eyes
Specialised photoreceptors in our retina called intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths
Your Brain Gets the Signal
When stimulated by blue light, these cells send signals to the suprachiasmatic nucleus (SCN) in the hypothalamus
Your Body Thinks It’s Daytime
The SCN interprets this as a signal that it's daytime
Melatonin Is Suppressed
In response, melatonin production is suppressed
You Stay Alert When You Should Be Sleeping
The result: increased alertness when our bodies should be preparing for sleep
Built to protect your sleep
Our lenses block the specific blue light wavelengths that interfere with melatonin — without distorting the rest of your vision.
The Proof
SOMNISE was selected as the blue light blocking glasses of choice for a recent Harvard-affiliated study. Over 831 nights tracked across 31 participants, the results were clear.
Clinically tested over 831 nights of real-world use, SOMNISE blue light blocking glasses helped users sleep 21 minutes longer and wake up feeling significantly more refreshed. In this 28-day study, 8 in 10 participants reported better rest quality when wearing the glasses before bed – results that proved statistically significant (p<0.001).
72% of participants specifically praised the blue light glasses in their feedback, with multiple users calling them "the most impactful" product out of several sleep products being tested. Users reported their eyes feeling "heavy" and "sleepy" within minutes of wearing the glasses, helping them fall asleep faster and wake up more rested. Several participants noted falling asleep in under 5 minutes, while others called the glasses "a game changer" for working late on screens.
These findings are consistent with independent research: individuals with insomnia gained 30 minutes of additional sleep wearing blue light blocking lenses before bed (Shechter et al., 2018), while separate research showed blue-blocking glasses advanced the body's natural melatonin release by nearly half an hour (Liset et al., 2021).
