The Science Behind Blue Light Blocking
Understanding Blue Light
Blue light is a high-energy visible (HEV) light with wavelengths ranging from 380 to 500 nanometres. While natural blue light from the sun is essential for regulating our sleep-wake cycle and boosting alertness, artificial blue light from screens can be harmful, particularly with prolonged exposure.
Impact on Sleep
Exposure to blue light, especially during the evening, can interfere with the production of melatonin, a hormone that regulates sleep. This can lead to difficulties falling asleep and poor sleep quality. Wearing our glasses in the hours leading up to bedtime can help maintain your natural sleep cycle, promoting better sleep.
Multi-mode Blue Light Blocking
FULL SPECTRUM MODE
Brighter light akin to the sun-rise to get your body moving in the morning.
AMBER MODE
A soothing sunset-orange light that mimics the ambience of reading by a campfire.
RED MODE
Completely free from blue and green light, this optimal red light setting is perfect for late-night reading or use in the middle of the night.
Benefits of Blocking Blue Light
Exposure to blue light in the evening can interfere with your body’s natural sleep processes by suppressing melatonin, the hormone responsible for regulating sleep. Traditional lamps often contain blue wavelengths, which can trick the brain into staying alert. By switching to our TRU Light Bulb you create a sleep-friendly environment that promotes relaxation and supports a natural circadian rhythm.
How Red/Amber Light Helps You Sleep
Warm red and amber light closely resemble the colours of a natural sunset, helping to cue the body that it’s time to prepare for rest. By eliminating blue light, our Tru Light Bulb allows for a seamless transition into sleep, helping you to fall asleep faster and stay asleep longer. Whether used for reading or general bedroom lighting, this bulb fully supports your body’s natural circadian rhythm.
