What is Blue Light and Where does it Come From?
Over the past several years, there have been major improvements in the field of optics. Recent research has indicated that high-energy visible radiation (HEV), otherwise known as blue light, is severely damaging to our eyes. “Blue light,” or the shortest and highest-energy light ranging from 380nm-500nm within the visible spectrum, is essentially everywhere. Light travels from the sun through the atmosphere onto the Earth’s surface. The shorter, high-energy blue wavelengths collide with the air molecules causing blue light to scatter everywhere. This is what makes the sky look blue (pretty cool, right?). Cool up until the point of affecting the future of our eyesight. That is why everyone needs blue light filter sunglasses.
Blue Light: The Good and the Bad
Different ranges of blue light have different effects on our bodies. Some good, some bad. Blue light in the 470nm-500nm range is generally considered beneficial and provides natural reflexes protecting our eyes against light overexposure. In its natural state, your body uses good blue light from the sun to regulate your natural sleep and wake cycles, memory and cognitive performance. Good blue light also helps boost alertness, improve reaction times, elevate moods, and increase the feeling of well-being.
On the other hand, bad blue light rays live in the range of 380nm-470nm, and this is the blue light we need to be concerned about. Lengthy exposure to this bad blue light may cause retinal damage and contribute to age-related macular degeneration, which can lead to an irreversible decrease in sharpness and clarity of vision.
So while some natural blue light is good for us, our eyes can’t naturally filter out or protect us against the bad blue light rays from the sun. This is where blue light filter sunglasses come in to play.
