It is reported that the myopia rate of Chinese adolescents is very high. According to a report released in 2020, the myopia rate of Chinese students has exceeded 70 percent. That number can even reach more than 80 percent in some cities. There are many factors that can cause this situation, including genetic, environmental, and educational aspects, of which light-environmental pollution is an important influencing factor.

Light environment pollution (Light Pollution) refers to the man-caused excessive and unreasonable emission of light sources, which have negative effects on the ecosystem, human health and social economy. In recent years, more and more attention has been paid to the effects of light environment pollution on human vision, including the relationship with myopia.

First, light environmental pollution can interfere with the natural regulation mechanism of human eyes, leading to myopia. At night, our eyes adapt to low light through dilated ation, but if the ambient light is too strong, it can weaken this adaptability, making it difficult for the eyes to properly adjust the focal length of the eye. In addition, light environmental pollution can also increase the incidence of eye fatigue and dryness, which can further affect vision.

Second, light environmental pollution may also cause myopia by changing sleep quality. Poor sleep has been shown to be a risk factor for myopia, and light environment pollution interferes with people's body clocks, leading to insomnia or decreased sleep quality, thus increasing the risk of myopia.

In addition, light environment pollution may also cause myopia by affecting children's visual development. Studies have shown that children affected by light environmental pollution before the age of 6 years may lead to long-term shortening of the ocular axis, which increases the risk of myopia.

In conclusion, the effect of light environmental pollution on human vision is a complex problem, but the relationship with myopia has been confirmed. Therefore, we need to take effective measures to mitigate the impact of light environment pollution on human vision. For example, reasonable planning of urban lighting layout, the use of intelligent lighting system, limit outdoor lighting at night, these measures can reduce the harm of light environment pollution to human vision. At the same time, people also need to pay attention to maintaining good sleep habits and eye health to reduce the incidence of myopia. And people who have myopia can see the world around them through myopia correction and improve the quality of life.

According to the 2021 market research report, the global market size of myopia correction instruments is expected to maintain steady growth in the next few years. The market is expected to reach about $3 billion by 2028, with a compound annual growth rate of 5.6%. This increase is mainly driven by the increasing awareness of the dangers of myopia and the search for more effective and comfortable methods of correction. The method of popular prevention and control myopia now has: orthokeratology lens, myopia operation to wait a moment, but these two kinds of methods have the defect of different degree.

The defects of orthokeratology lens to correct myopia mainly include the following aspects: 1. Inconvenient to wear: wear it before going to bed every night, and remove it every morning, which will bring some inconvenience to users.2. Adaptability problem: Some people may not be able to adapt to the feeling of wearing hard contact lenses, which may cause eye discomfort and other problems.3. High risk: wearing orthokeratology lens has risks of infection, allergy and eyeball damage, and improper use may lead to vision loss and other problems.4, the effect is limited: orthokeratology lens can only alleviate or temporarily improve myopia problems, but can not be completely cured, and for the higher degree of myopia effect may not be as obvious as the operation.

Some of the defects to correcting myopia include: 1. The operation is not permanent and may require another surgery or glasses / contact lenses.2. Surgical risks, including infection, corneal inflammation, and surgical failure.3. Dry eye symptoms or nighttime vision problems may occur after surgery.4. Detailed examination and evaluation are required before the surgery. If it is not suitable for the surgery, the operation cannot be carried out.

Therefore, we need a more effective and safe method, including the "clear, adjust, repair" vision prevention and control concept —— that is to remove light pollution, adjust ciliary muscle, supplement photonutrition. Not only can it solve vision problems perfectly, but can also ensure eye health.

First of all, "clear" is the light pollution. Modern people face computers, mobile phones and other electronic devices for a long time, and the blue light emitted by these devices is very harmful to the eyes. Glare, flashing light, infrared light, ultraviolet light can cause damage to the cornea and iris of the human eye, causing fatigue and macular degeneration and other problems. To solve these problems, we need to use light-cleaning lamps to remove light pollution and protect our eyes. For example, the use of clean-up light in the office or at home will reduce the number of blue light directly exposed to the eye, thereby reducing the burden on the eye.

Secondly, "tuning" is to adjust the ciliary muscle with the eye adaptation trainer . The ciliary muscle is an important eye muscle, which undertakes the task of adjusting the focus length of the eye, and it needs its help when we look at near and far objects. In modern society, more and more people are in the sitting position, supine position and other fixed positions for a long time, making the ciliary muscle is often in a state of tension, thus leading to its health decline. The invention patent technology (patent number: ZL 2021 2 1515482.6) is a comprehensive training technology that combines the eye protectors and eye protectors. To put it simply, it is to train the visual nerve by changing the mentality of the brain imaging ability, activate the retinal nerve through the mind imagination, and constantly update the data of the brain. Combined with the contraction of the ciliary muscle in the use of eye protectors, the vision is controlled and improved.

Finally, "supplement" is to supplement the sunshine nutrition instrument to supplement photonutrition. Photonutrition is indispensable to protecting eye health. Because most of us are indoors for long times, our eyes are unable to get enough natural light. This leads to many eye problems, such as dry eye disease, retinopathy, etc. To this end, we need to use the device to supplement the eyes due to the lack of outdoor activities caused by the lack of light nutrition, care for eye health.

To sum up, the vision correction method combining "clearing, adjusting and filling" is not only safer and more effective, but also can help us solve eye problems and make our eyes more healthy and bright. Eyes are the window for people to perceive the world, protect their vision, and open a new era of visual health.
