What are the effects of blue light exposure on children?

Blue light therapy is an important treatment option that can eliminate certain diseases, especially eye diseases. However, children's bodies are very fragile, and they cannot undergo various treatments at will. For example, blue light therapy will cause some health problems for children. Therefore, if blue light therapy is to be carried out, the systems of various hospitals should be strictly abided by before the treatment methods can be determined. So, what are the effects of blue light exposure on children?

The outside of our eye is the cornea and the inside is the retina. Although the cornea is very powerful and only less than 1% of ultraviolet rays can penetrate the retina, it is completely defenseless against blue light, which can penetrate the cornea directly and reach the retina.

Experts at the 2010 International Photonics Association Annual Meeting unanimously pointed out that excessive blue light can damage the photoreceptor cells in the retina and cause macular degeneration.

Degeneration), which can lead to visual distortion, decreased vision, and in severe cases, blindness.

Have you ever noticed that staring at the screen and reading is not as focused as reading a paper book? That's because blue light is easily scattered, and the large amount of blue light emitted by the screen makes it impossible for the eyes to concentrate, thus causing eye fatigue. Long-term visual fatigue can cause problems such as dryness, pain and myopia.

With the increasing number of electronic products, the number of cases of digital visual fatigue (DEF) is also increasing. Blue light is the main cause of digital visual fatigue. Every year, more than 400,000 people in China go to the hospital for checkups due to eye fatigue, and blue light is the main cause of digital visual fatigue!

Glare refers to visual discomfort caused by inappropriate brightness distribution in the field of vision. In severe cases, it can cause nausea, discomfort or even loss of vision. Because blue light has a higher rate of scattering when encountering tiny particles in the air, this is the main cause of glare.

4. Affect sleep and cause fatigue and weakness.

Blue light inhibits the secretion of melatonin, which is an important hormone that affects sleep. Its currently known functions are to promote sleep and adjust jet lag.
