In our digital world, screens take up most of our time. Increased screen use may affect vision and sleep patterns. The main reason for this situation is blue light. The blue light emitted by electronic digital devices can cause serious damage to your eyes. But in this case, if anti-blue light technology is used properly, it also brings some solutions to users.

Screen protectors made with anti-blue light technology are quite useful. These screen protector can protect both adults and children.

What is Blue Light?

The sun is the main source of blue light. And later, light sources also came from candles and light bulbs. With the development of technology, there are more and more light sources, such as televisions, smart phones, computers and other electronic devices.

Each color of light in our visible spectrum has a different amount of wavelength and energy. At the other end of the spectrum, you'll find blue light. It is more vibrant and has a shorter wavelength than other colors.

How blue light affects us?

Since blue light is widely used in our lives, our chances of being exposed to blue light have increased. However, overexposure to blue light can be harmful. Exposure to blue light, especially at night, may suppress melatonin production, reduce the quality of our sleep, and may make us feel tired the next day.

It is necessary for our bodies to receive some blue light. Research shows it's important for our normal sleep and wakefulness. Blue light can also control our emotions. Additionally, blue light remains effective in strengthening our immune system. If the amount of blue light received through different devices is higher than normal, several side effects can occur.

For example, eye fatigue, headaches, difficulty concentrating, blurred vision, etc. Greater risk of various cancers. Long-term exposure to it may cause permanent damage to your eyes. Additionally, people who are regularly exposed to excess blue light have been found to have significantly higher rates of depression or other mental disorders.

What is anti-blue light technology?

There are two types of anti-blue light technology. The other is reflective anti-blue light. It mainly uses film technology to cover the surface of the glasses lens with a high-reflectivity anti-blue light film layer, which will absorb a certain degree of ultraviolet and short-wave radiation in the external environment. Harmful radiation such as blue light is reflected back. One is to absorb blue light, using light complementary technology to absorb higher-energy blue light by adding specific dyes and coating treatments, thereby achieving the anti-blue light effect. For example, Perfectsight adds a rare earth eye protection coating to the surface of the iPhone screen protector to achieve anti-blue light and eye protection effects, and can filter up to 69% of blue light.

How can anti-blue light technology help us?
For example, children are at risk because their eyes are not fully formed until they are ten years old. Therefore, blue light may have a negative impact on their health. Therefore, it is necessary to choose an anti-blue light mobile phone film or anti-blue light glasses.
