Light is everywhere,
and it’s always on
Today, we live in an on-the-go society that is always “on”. In other words, humans no longer solely rely on sunlight and fire. We have light bulbs that illuminate our homes, office buildings, gyms, malls, and airports. And thanks to digital devices with LED screens (tablets, smartphones, laptops, etc.), we now have the power of light literally at our fingertips.
Natural Sunlight
Sunlight is comprised of red, orange, yellow, green, blue and violet light rays (the visible light spectrum). It’s specifically the blue rays that suppress melatonin levels and promote alertness.
Artificial Light Issues
Blue light is responsible for signaling to your brain that it’s time to wake up in the morning or go to sleep at night time. The key difference and problem that arises from using artificial light sources is that they mostly emit blue instead of the full visible light spectrum.
Circadian Rhythm
Many doctors and researchers are concerned about the amount of time people spend using digital devices, and the proximity of these screens to the user’s face, as these variables could have possible long-term effects on eye health, such as macular degeneration (the leading cause of blindness). At the very least, prolonged exposure to artificial blue light, or “junk light”, can unbalance your natural circadian rhythm.
Truedark technology
Key to Managing the Your Light
Remember that the sun changes its position in the sky and emits different amounts of blue light throughout a cyclical 24-hour period. In order to keep your natural circadian rhythm aligned with the rise and fall of the sun, your body needs different amounts of blue light to promote either wakefulness or sleepiness. That is why TrueDark provides an authentic 24-hour solution to help you block out the right amount of junk light at the right time of day (or night).
In this graph, the red line symbolizes cortisol, which promotes alertness. The blue line symbolizes melatonin, which promotes sleepiness. This pattern repeats every 24 hours.

How exposure to junk light affects your brain and body
Harmful blue light penetrates the macular pigment and can harm the retina.
When the melanopsin proteins detect blue light, they then suppress your body’s ability to produce melatonin, disrupting your natural sleep pattern.
