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.
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.
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.
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.
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).
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.
Our four featured lens colors plus transitional sunglasses for Daylights allows you to choose the ultimate protection for your eyes against digital eye fatigue and enhance your melatonin for better, deeper sleep.
When Dave Asprey set out to help people manage their light so they can live better quality lives, he knew light was a big challenge. He answered the issue with TrueDark technology imbedded in his blue light managing glasses.
Some people may have mixed insomnia that involves both sleep-onset and sleep maintenance difficulties, and people with chronic insomnia may find that these symptoms shift over time.
