AMOLED displays are known for their vivid colors, high contrast, and deep black levels. While they offer many benefits, they can cause eye strain and other health issues in some cases.
One of the main issues with AMOLED displays is that they emit blue light.AMOLED displays have red, green, and blue sub-pixels that emit light independently to create a full color image. To create the blue color, AMOLED displays use a blue organic material that emits blue light when an electric current passes through it.
The blue organic material used in AMOLED displays emits light in a wavelength range that includes a significant amount of blue light. Blue light is a type of light that has a short wavelength and high energy, while blue light is necessary for creating a full color image on an AMOLED display, it can also cause eye strain and other health issues, especially when the screen is viewed for extended periods of time.
Exposure to blue light, especially at night, can disrupt your body's circadian rhythm, making it harder to fall asleep and stay asleep. This is because blue light suppresses the production of the sleep hormone melatonin, which is produced by the pineal gland in the brain in response to darkness.
Extended exposure to blue light can also cause digital eye strain, also known as computer vision syndrome. This condition can cause symptoms such as dry eyes, blurred vision, headaches, and neck and shoulder pain. Digital eye strain can occur when you spend long periods of time looking at a digital screen, such as a computer or smartphone.
To reduce the risk of blue light exposure from AMOLED displays, you can use a blue light filter or a blue light-blocking app on your device. These filters can reduce the amount of blue light emitted by your screen, making it easier on your eyes and helping you sleep better.
Additionally, you can adjust the brightness of your screen and take regular breaks to give your eyes a rest. Experts recommend the 20-20-20 rule, where you take a 20-second break every 20 minutes to look at something 20 feet away.
