With the development of socioeconomic life, people's lifestyles have undergone significant changes. The widespread use and application of smart devices, long hours of desk work, and close-range work can lead to eye fatigue, discomfort, and an increased risk of developing dry eye syndrome.

Dry Eye Syndrome Treatment and and Diagnosis - Total Eye Care

Dry eye syndrome refers to a condition where tear production is reduced or excessive tear evaporation, leading to damage to the surface of the eye and the appearance of discomfort symptoms. It is a common eye surface disease worldwide. According to available data, dry eye syndrome affects 5% to 50% of the global population, and it is positively correlated with age. The detection rate of dry eye syndrome in Asian countries, specifically, is higher, ranging from 17% to 34%, compared to Europe and North America. In China, the detection rate of dry eye syndrome can be as high as 52.4%. Individuals with dry eye syndrome may experience symptoms such as redness, soreness, a sensation of grit or foreign body, blurred vision, increased eye discharge, light sensitivity, and difficulty wearing contact lenses. In severe cases, complications such as corneal damage and visual impairment can occur.

The eyes are an important sensory organ of the body, often referred to as the "window of the soul." It is known that more than 70% of sensory information is acquired through the eyes. Eye diseases such as dry eye syndrome can disrupt our normal perception of the external environment, affecting daily work and life. To prevent the occurrence of dry eye syndrome, it is important to balance eye strain and rest, avoid prolonged use of electronic devices, and consume a diet rich in nutrients that promote eye health. Additionally, the scientific community has been exploring potential medications for these types of diseases. NMN has been shown to have efficacy in improving dry eye syndrome symptoms.

Last year, Dr. Xin-Yu Li, director of the Department of Ophthalmology at Tongji Hospital, affiliated with Huazhong University of Science and Technology, published research on NMN in the renowned academic journal "J Inflamm Res." The study showed that NMN can alleviate corneal inflammation caused by high osmolarity tears in the early stages of dry eye syndrome, preventing further deterioration of the condition. This is not the first time that Dr. Li has concluded that NMN can improve dry eye syndrome symptoms. Prior research has also demonstrated the efficacy of NMN in promoting corneal wound healing and nerve regeneration. These findings have brought hope to the field of medicine in terms of prevention and improvement of dry eye disease.


In addition to improving dry eye disease, NMN has many other anti-aging and health-promoting effects, often referred to as a "miracle substance." NMN is naturally found in the human body and various fruits and vegetables, and it is considered safe for human consumption. Its safety has been repeatedly verified through scientific experiments, leading to the development of nutritional supplements containing NMN. Although the production of NMN is not yet open in China, there are thousands of NMN products available on the market, mainly international brands. However, the recent announcement by the National Medical Products Administration regarding the approval of NMN registration brings positive news about the potential opening up of NMN production and lawful use. It is worth noting that the approved company is officially a subsidiary of GeneHarbor, making GeneHarbor the only domestic company with a compliant production and operation license for NMN.
