Macbook Pro 16 blue light screen protector: Generally, scientists say the visible light spectrum comprises electromagnetic radiation with wavelengths ranging from 380 nanometers (nm) on the blue end of the spectrum to about 700 nm on the red end. (By the way, a nanometer is one billionth of a meter — that’s 0.000000001 meter!) Blue light generally is defined as visible light ranging from 380 to 500 nm. Blue light sometimes is further broken down into blue-violet light (roughly 380 to 450 nm) and blue-turquoise light (roughly 450 to 500 nm).
Understanding the physics of light and how it interacts with the human eye is the first step to understanding why too much of it can be bad for us. All light is waves, and different colors have different energies. Towards the beginning of the visible spectrum is red light, made up of low energy waves. This light is easier on our eyes, especially at night. As we get closer to the higher energy side of the spectrum, light becomes more tiresome for our eyes to process. Blue light occupies the highest energy portion of the visible spectrum. It penetrates all the way to the retina in the back of the eye.

Dry eye can result in a series of problems with your eyes apart from making your eyes irritated or itchy. Although dry eyes can be linked to your age, you can take measures to prevent it, like using eye drops or turning on the humidifier in your home or office to relieve the condition. If it persists, you can contact your optometrist for advice or treatment. You may have to stop diuretic medicine. If you walk in the sun often or the nature of your work requires spending a few hours in the sun, protect your eyes by wearing sunglasses to protect your eyes from the ultraviolet rays that come from the sun. The ultraviolet rays can damage your eyes. Why endangering your eyes when you can get a good pair of sunglasses for a few bucks?
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.
