Why do we need to use anti-blue light products to protect our eyes?

Modern people spend more and more time using electronic products such as mobile phones, tablets, and computers, all of which emit blue light. When we use electronic products, our eyes need to constantly focus and adjust to the light on the screen, which can lead to eye fatigue, discomfort, and decreased vision. Blue light has a shorter wavelength than other light, making it easier to penetrate the back of the eye and cause damage. Long-term exposure to blue light can damage the eyes, such as causing vision loss and eye fatigue. Therefore, many manufacturers have started producing anti-blue light products that can reduce the harm caused by blue light to the eyes.

The scientific principle of anti-blue light products is to reduce the amount of blue light radiation through filters, coatings, anti-blue light agents, or other technologies, thus reducing the stimulation to the eyes. In addition, anti-blue light products can also reduce eye fatigue by lowering the screen's flicker frequency, making the image more stable.

Some anti-blue light products use advanced optical coatings to reduce the wavelength and intensity of blue light, thereby reducing the stimulation to the eyes. Other anti-blue light products use reflection or scattering techniques to reflect or scatter blue light elsewhere, reducing the amount of blue light entering the eyes.

Scientific research has shown that long-term exposure to blue light can cause oxidative stress on retinal cells, which can affect eye health. Oxidative stress is a biological damage response that can cause DNA damage, cell death, and eye diseases such as macular degeneration and cataracts. Studies have shown that the effects of prolonged use of electronic products on children and adolescents are particularly significant because their eyes are still developing and more susceptible to the effects of blue light.

However, it is worth noting that anti-blue light products cannot completely eliminate the harm caused by blue light. Scientists are still exploring the effects of blue light on the eyes and how to better protect them. In addition to using anti-blue light products, we should also pay attention to controlling the time we spend using electronic products, taking proper breaks, and maintaining a proper distance to reduce harm to the eyes.

Using anti-blue light products is still a good choice, especially for people who use electronic products for long periods of time.
