WHAT IS BLUE LIGHT? WHAT ARE THE EFFECTS OF BLUE LIGHT EXPOSURE ON OUR HEALTH
- Blue light is a color in the "visible light spectrum" that can be seen by the human eye.
- Blue light has a wavelength of between approximately 380nm and 500nm (nanometers); making it one of the shortest, highest-energy wavelengths.
- Sources of blue light include the sun, digital screens (TVs, computers, laptops, smartphones, and tablets), electronic devices, and fluorescent and LED lighting.
- In a series of studies, it has been demonstrated that blue light is a fundamental requirement to initiate aspects of circadian rhythm. These studies have shown that a small percentage of retinal ganglion cells contain a pigment, melanopsin, whose absorption of blue light triggers a mechanism via the brain which regulates melatonin levels in the blood.
- When the retina is exposed to light with a blue component the absorption within melanopsin initiates a process whereby melatonin production is suppressed, and the individual exposed “wakes up.” By contrast, switching off absorption at night regulates melatonin production, and the individual goes to sleep.
- High exposure to blue light at night can impact the quality of your sleep.
- Because they are shorter, these "Blue" or High Energy Visible (HEV) wavelengths flicker more easily than longer, weaker wavelengths. This flickering and glaring may also be one of the reasons for eyestrain, headaches, physical and mental fatigue caused by many hours sitting in front of a computer screen or other electronic device.
HOW OUR GLASSES PROTECT YOU AND YOUR KIDS FROM THE BAD BLUE LIGHT
- The human eye is not very good at blocking blue light. Virtually all visible blue light passes through the cornea and lens and reaches the retina.
- Please limit the use of electronic devices or your exposure to LED lights from 7 PM onwards.
- We have developed a special lens that blocks up to 85% of the bad blue light.
- By wearing The Blue Busters® glasses at least 2 hours before going to sleep you will be protecting the melatonin production, and therefore the quality of your sleep.
