Effects of blue light technology

Blue light technology is a type of light that comes from screens on phones, tablets, computers and TVs. This special kind of light can have both good and bad effects on our eyes and bodies.

When we look at a screen for a long time, our eyes can get tired and feel strained. This is because the blue light from the screen can make it hard for our eyes to focus. It can also make it hard for us to fall asleep at night, because our brains think it's still daytime when we look at screens with blue light.

However, blue light also has some good effects. Exposure to blue light can help our brains stay alert and focused. It can also make us feel happier and more awake, especially when we are exposed to it in the morning.

So, while blue light technology can be helpful in some ways, it's important to remember that using screens for long periods of time can have negative effects on our eyes and sleep patterns. To help reduce these effects, we can try to take breaks from screen time or use special glasses that block blue light.
