Blue Blockers Glasses is very important.

Electronic products appear in people's lives in a variety of patterns, such as: mobile phones, VR products, touchscreen whiteboards, smart desk lamps, etc. This is why many parents are very concerned that curious children who are addicted to the fun of electronics will cause not only a decline in academic performance, but also a worrying condition of their children's eyesight. For the sake of children's eye health, parents are very concerned about all kinds of eye care tips, including "Anti-Blue Light".

1⃣ Almost all of us hold our phones every day and let the blue light radiation and visual fatigue hurt our eyes

2⃣ China's myopic population has reached 600 million and is expected to reach 700 million myopic people over the age of 5 by 2020!

3⃣ 100% ocular lesions in middle-aged people over 50 years of age.

4⃣ Nearly 150,000 eyes worldwide.

"Can anti-blue-light glasses prevent myopia?" The voices for and against it on the Internet are evenly matched. If we want to know "Can blue light glasses prevent myopia", we need to know what is myopia?

Nearsightedness is when the eye is in a relaxed state and light cannot focus on the retina after the refractive system of the eye works, but instead focuses on the front of the retina, causing the eye to see only what is near but not what is far away.

There are two main causes of myopia: genetic and environmental. Myopia has certain genetic factors, especially in families with high myopia, which are inherited in a variety of ways, some are autosomal dominant, some are autosomal recessive, and some are a mixture of both. Whereas, the environment refers to looking at things in bright and low light for long periods of time, causing the ciliary muscles to be under tension, and the ciliary muscles control the length of the eye-axis, causing it to lengthen causing myopia.

Blue light has a short wavelength and 60% higher energy than yellow-green light. Short-wave high-energy blue light, on the one hand, 430nm-480nm wavelengths after passing through the lens, the focus of the blue light falls in front of the retina. When we want to see something, we can only change the shape of the lens by tightening the ciliary muscles so that the curved surface of the lens allows the focus of the blue light to move to the retina. When you use 3C electronics for a long time, the eyes are irradiated for a long time causing the ciliary muscles to be under constant tension, causing eye fatigue.

On the other hand, blue light penetrates the lens directly onto the retina, forming a high-energy accumulation of blue light energy, which can easily cause retinal damage and macular degeneration, vision loss, because the retina does not have the ability to regenerate, vision is irreversible recovery, which will cause a lifetime of regret.

So blue light does cause myopia. Therefore, it is true that blue light protection also prevents the increase of myopia.
