The patent inventor of the Gulu instrument contacts this newspaper: Products may cause vision damage

The Yangtze River Daily Da Wuhan Client July 28 (Reporter Zhao Jiaxin) A few days ago, the Yangtze Daily reported that the hot -selling instrument on the Internet may cause damage to the child's eyes. On the morning of the 28th, Dr. Sha Shao Gen, a patent inventor of this product, took the initiative to contact this book. The report explained to the reporter in detail the time of the listing of Yuguang instruments and the uneasy of many ophthalmologists to the product.

Shao Ligong is a doctor of eye science and visual development science at the Ministry of Medicine of Peking University, an expert in the National Natural Science Foundation of China, and the director of the Guidance Center of the National Natural Science Foundation of China.

Shao Ligong told reporters that in 2003, he and his colleagues applied for the patent of myopia amblyopic therapy instruments, but then he consulted a large amount of information in Europe, the United States, Japan and other countries. The patient caused vision damage, and Shao Ligong decided not to use the patent to transform the results. After a few years of the patent, some merchants found him, saying that he used his patent to produce products for the treatment of myopia. He hoped to be authorized by Shao Ligong and was rejected by Shao Ligong.

The reporter learned from the national patent department that at least 19 patents under the name of "Yuguang instrument", only 19 patents involve two categories: Chinese invention and Chinese practical type. Shao Ligong said that in fact, these patent principles are consistent with what he initially applied, but only made some changes in the appearance of the product, and he retained his accountability of these products.

On June 3 this year, the Professional Committee of Children's Eye Disease Prevention and Treatment of the China Eugenics Association specifically mentioned in the "National Eye Love Day" initiative. Nano -semiconductor red laser, deliberately avoiding the word "laser", may induce and lead to severe damage to children's and adolescent eye health. The international laser medicine safety protection manual stipulates that the red laser of 650 nanometer semiconductor is relatively safe, which refers to an inadvertent eye -catching eye, instead of intermittently shot the eyes or deliberately staring at the laser.

Professor Chu Renyuan is one of the founders of the medical optometry machine medical mirror in my country. Over the years, it has undertaken and completed multiple scientific research projects at the state, ministry and municipalities, and has won many results awards. According to Professor Chu Renyuan, research shows that 650 nanometer semiconductor red laser below 0.3 mile power must be accurate to protect the stabilization of the laser diode circuit without changing the stabilization. And if this laser device stares for a long time, or deliberately condense for a long time, or is irradiated, it will produce laser eye heat energy accumulation and laser chemical toxicity, leading to irreversible damage to the eyes, especially chronic gradual congestion, edema and degeneration of retinopasus. The thermal energy accumulation with the laser focusing on the macular area, and the chronic burning effect caused the macular region three -level neurons, cone watting rod cells, and pigment epithelial cells to degenerate, and permanent vision damage effects occur.

Shao Ligong said that after 5 to 10 years of suspension of such laser, the retinal veins and pigment epithelial cells will appear. Gradient atrophy, degeneration and decreased vision of vitreous vitreous and liquefaction will appear. Low -intensity red laser radiation damage lesions such as cataracts such as cataracts should attract great attention.

The reporter learned that in June last year, the relevant departments of Shaanxi Province issued public documents to perform testing requirements for a certain light instrument product because there was a report that the product may cause irreversible vision damage to patients with myopia patients in young children.
