What is blue light? Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call “white light” or sunlight.
What are blue light blocking glasses? It is a particular type of glass fitted with filters in the lenses to absorb or block blue light and, in some instances, other detrimental lights from getting through to the user’s eyes. Therefore, the use of these glasses against screens can help reduce exposure to a wave of lights that can keep you awake, especially at night. Exposure to harmful blue light does not mean the end of life. It is presumed that blue light blocking glasses are useful in filtering the blue light, thus restore healthy life to individuals affected. Wearing blue light blocking glasses means healthy sleep, thus reducing the chances of other risks. Read a few more info on what are blue light glasses.
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.
Avoid dry eyes. As stated above, the primary reason staring at a computer screen is so harmful to your eyes is that you tend to blink less. To combat dry eyes, keep artificial tears nearby and use them when necessary. Other factors that can cause dryness include humidity-controlled offices that pull moisture out of the air and, during the winter, heaters. A desktop humidifier can help introduce moisture into your environment and give your eyes some relief.
Blue light exposure may increase the risk of macular degeneration. The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important, because laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina. This causes changes that resemble those of macular degeneration, which can lead to permanent vision loss. Although more research is needed to determine how much natural and man-made blue light is “too much blue light” for the retina, many eye care providers are concerned that the added blue light exposure from computer screens, smartphones and other digital devices might increase a person’s risk of macular degeneration later in life.
