Blue light is part of the visible light. The full visible light spectrum is made of several colors. Some of the prominent colors include; orange, yellow, red, and blue. Since visible light falls under the electromagnetic wave spectrum, each emitted color carries specific energy, wavelength, and frequency. The higher the frequency of a given color of light, the higher the electromagnetic energy carried by that specific light, and the deeper such a light radiation can penetrate an object.
Among the visible light spectrum colors, blue light has the shortest wavelength and the highest frequency. This implies that it has the highest energy and the highest penetration capabilities. This penetration energy has been associated with several health complications.
Some of the effects of the blue light emitted by smartphone screens include retina damage, digital eye strain, and age-related muscular degeneration (AMD). The blue light has also been associated with cancer and has been proved to have the potential to cause long-term eye complications.
Samsung Galaxy Note 9 comes with several options which can be used to protect yourself from such eye complications. If you are eager to learn how to use blue light filter feature on Samsung Galaxy Note 9, follow up to the end of this article.

There are screen protectors which have the capability to filter the blue light emitted by smartphones. These anti-blue light screen protectors have a thin coating made up of materials which have been scientifically proven to filter the blue light. Most of these anti-blue light materials which make up this coating are made from polycarbonate or acrylic plastic. The materials not only filter the blue light but other higher energy electromagnetic waves such as Ultra Violet light.
By filtering blue light from entering the eye, the anti-blue light screen protectors effectively protect the eye from the negative effects of blue light. These protectors are attached on smartphone screens making them convenient for use. You will need to purchase a protector for each device to ensure that your eyes are protected across all the devices.
Smartphones have proved to be quite useful in the various aspects of modern life. Though these smartphones are loaded with benefits, they still have drawbacks. One of these is the negative effects caused by the emission of blue light by the smartphone screen.
