So, stay tuned to learn how you can filter blue light from your digital devices.

What is Blue Light?

Visible light from the sun and the display of your digital devices is made up of colors with varying wavelengths and energy levels. Colors include red, orange, yellow, green, blue, indigo, and purple. Blue light, which includes both indigo and violet light rays, has short wavelengths and high energy. Devices such as computers, TVs, smartphones, tablets, and LED lamps contain artificial blue light. The blue light of the sun is beneficial in that it regulates your body clock and also helps in the proper development of children’s vision.

Due to its high energy level, blue light leads to a state called digital eye strain. If you are experiencing pain, fatigue, and dry eyes in your back and upper body with episodes of pain and soreness, then your digital eyes are strained. Macular degeneration is another consequence of over-exposure to blue light from devices. It is an age-related disease where your retinal cells break down slowly. Blue light increases the chances of developing this condition in your life. Macular degeneration makes you look blurry as it attacks the space responsible for defining your point of view.

Effect of blue light on sleep

Naturally, you never had to get acquainted with the blue light at night. Blue light from sunlight is something that keeps you alert during the day and promotes cognitive functions such as memory. In developed and developing countries, most people have access to digital devices and the Internet, and because of this, they continue to work and entertain in the light of day. This keeps them awake and alert until late at night and makes it really difficult to catch sleep.

The brain detects the absence of blue light and stimulates the release of melanton, a hormone that helps you sleep. If you work on your Mac at night, the brain interprets the presence of blue light as the time of day. It stops the production of melatonin and when you retire to bed, it takes time for you to fall down and fall asleep. Repeated exposure to blue light at night can cause a change in your circadian rhythm, which means you will suffer from chronic insomnia.

The cause of blue light harm is purely biological. Sleep is a part of the circadian rhythm, a cycle of biological processes that are partially determined by the levels of light and darkness in our bodies. In the most natural environment, which is a place where we are only exposed to sunlight, our retina is felt when our sunsets and the atmosphere deepens. It stimulates our hypothalamus to produce melatonin and other sleep hormones and to begin the process of lowering our body temperature.
