On the other end of the visible light spectrum, blue light rays with the shortest wavelengths (and highest energy) are sometimes called blue-violet or violet light. This is why the invisible electromagnetic rays just beyond the visible light spectrum are called ultraviolet (UV) radiation.

Adults have their own issues to deal with. As we age, our eyes “remember” and retain energy. Blue light not only penetrates all the way to the retina in the back of the eye, it builds up over time. The cumulative effect causes eye strain, dry eye, and unnecessary exhaustion. Because of its temperature and frequency, blue light tends to affect both the retina and the cellular anchors, leading to early onset of Advanced Macular Degeneration, an issue which must be corrected through surgery. Consistent melatonin disruption has also been linked in recent studies to an increased risk of obesity and some cancers.
You may be wondering why using a computer is so much harder on your eyes than reading printed materials like a book or magazine. The main reason is that when we stare at computer screens, we tend to blink less. In fact, while focusing on digital displays, a person’s blink rate can be reduced by a third to a half, which causes their eyes to dry out. Additionally, many of us are not viewing these screens from the optimal distance. In recent years, a popular solution to this problem has been blue light filters; namely, expensive computer glasses. However, these glasses, as well as other blue light filters, are no more effective at reducing the symptoms of eye strain than a neutral filter. Instead of spending money on something that may not help, try these simple and effective tips first.
Like ultraviolet radiation, visible blue light — the portion of the visible light spectrum with the shortest wavelengths and highest energy — has both benefits and dangers. Here are important things you should know about blue light: Blue light is everywhere. Sunlight is the main source of blue light, and being outdoors during daylight is where most of us get most of our exposure to it. But there are also many man-made, indoor sources of blue light, including fluorescent and LED lighting and flat-screen televisions. Most notably, the display screens of computers, electronic notebooks, smartphones and other digital devices emit significant amounts of blue light. Find more details on this website.
