What is blue light and why is it harmful?

Blue light is a type of visible light that has a short wavelength and high energy. It is emitted by the sun, but also by artificial sources such as LED lights, computer monitors, TVs, and smartphones. While some exposure to blue light is beneficial for your health and mood, too much can have negative effects on your eyes and sleep.

Blue light sources and effects

According to the American Academy of Ophthalmology, blue light can cause eye strain, dry eyes, blurred vision, headaches, and even damage the retina over time. This is because blue light penetrates deeper into the eye than other colors, and can cause oxidative stress and inflammation in the cells. Moreover, blue light can also affect your circadian rhythm, which is your natural sleep-wake cycle.

How blue light affects your sleep cycle

Your circadian rhythm is regulated by a hormone called melatonin, which is produced by your brain when it gets dark. Melatonin signals your body that it is time to sleep, and helps you fall asleep faster and stay asleep longer. However, when you are exposed to blue light at night, your brain thinks that it is still daytime, and suppresses the production of melatonin. This can make it harder for you to fall asleep, or cause you to wake up frequently during the night. As a result, you may feel groggy, irritable, or depressed the next day.

It works by applying a warm-colored overlay on top of your screen, which filters out the blue light and makes the screen more comfortable for your eyes. By using blue filter apk, you can protect your eyes from strain and damage, and also improve your sleep quality.
