Patients with presbyopia usually do not take the initiative to seek medical treatment, and generally choose to buy presbyopia without wearing or undergoing optometry

Why do people over the age of 40 have a high incidence of nearsightedness

　　"Daily wear a pair of glasses, change a pair when driving, and change a pair when working, and switch between three pairs of glasses a day..." These scenes are the daily life of myopia plus presbyopia patients. At present, China's population over 35 years old, 56.9% of the population with presbyopia problem, reaching 390 million, accounting for nearly 30% of China's total population. However, due to lack of cognition, the number of presbyopia patients and the number of corrections are seriously unequal.

　　The 45th Statistical Report on Internet Development in China shows that as of March 2020, the number of Internet users in my country reached 904 million, and the number of mobile Internet users reached 897 million. Among netizens, 50-year-old and Internet users accounted for 16.9%, and the number exceeded 150 million. "Middle-aged and old-fashioned low-headed people" are rising.

146 million people with moderate to severe presbyopia

　　Presbyopia, also known as presbyopia, is a physiological phenomenon. With age, the lens hardens, the elasticity weakens, and the contraction of the ciliary muscles decreases. As a result, the adjustment decreases, and the near point moves far, so it is difficult to see objects at close range. The book "Presbyopia Surgery Correction-The Fifth Wave" pointed out that presbyopia usually appears around 38 years old, and the peak incidence is around 42 to 44 years old.

　　According to the survey data of "2018 Market Scope", there are currently nearly 1.8 billion presbyopia patients in the world, China's population over 35 years old, 56.9% of the population with presbyopia, reaching 390 million; moderate to severe presbyopia, reaching 146 million; severe The presbyopic crowd reaches 8 million. The "National Visual Health Report" pointed out that visual impairment has become a major public health problem in my country, and cataracts and presbyopia are important factors that threaten our national visual health.

　　"Unlike myopia or cataracts, presbyopic patients usually do not take the initiative to seek medical treatment and conduct professional eye examinations. They generally choose not to wear or wear presbyopic glasses at will. If they do not undergo optometry, they will buy presbyopic lenses themselves." Professor Wang Zheng, the lead drafter of the industry standard for Laser Corneal Refractive Surgery and the deputy director of the Refractive Surgery Committee of the Ophthalmologists Branch of the Chinese Medical Association, emphasized that the wrong way of coping will make the eyes fatigue for a long time and may cause crystals Accelerate aging. In developing countries, 94% of uncorrected visual impairment is due to presbyopia. "Presbyopic patients generally think that presbyopia can't be cured without treatment, and the lack of correct recognition that they can obtain visual quality improvement through active surgical intervention is the biggest challenge to improve the visual health of presbyopic patients."

Middle-aged and elderly people have a high incidence of nearsightedness

　　"The 150 million Internet users over 50 years old happen to be a group with a high prevalence of presbyopia. There is an irreconcilable contradiction between their nearsightedness and nearsightedness, which can only be solved by wearing glasses or surgery." Professor Zhou Jin, a member of the Sichuan Provincial Ophthalmology Special Committee and the deputy director of the Sichuan Provincial District of Aier Eye Hospital Group, said, "While wearing presbyopia, although the near vision effect will be improved to a certain extent, the presbyopic patients' own lens high-order aberration Changes will inevitably cause the lens function to decline and the visual quality to decline, which cannot be solved by reading glasses."

　　Mr. Chen, a 49-year-old from Chengdu, is a dentist. He has nearsightedness of 925 degrees in the left eye and 750 degrees of myopia in the right eye. He has been "friendly" with his glasses for many years. But in the past six months, Mr. Chen felt that near vision was becoming more and more blurred. Due to his professional needs, he had to refit a pair of myopia glasses for his high requirements for nearsightedness. "I thought it was myopic power that caused my vision to increase again. It went down, but I couldn't see clearly even with new glasses." Realizing that his symptoms are probably presbyopia, Mr. Chen went to a pair of reading glasses. Wear old glasses every day to ensure medium and near vision, wear new glasses to ensure clear and far vision when driving, and wear reading glasses when working or using mobile phones to improve near vision. In this way, Mr. Chen, who has three glasses in his hand, does the most actions every day to take and change mirrors. After these days lasted for three months, Mr. Chen chose lens replacement presbyopia correction surgery.

　　The prevalence of nearsightedness among middle-aged and elderly working people like Mr. Chen is extremely high. According to the "Research Report on the Incidence of Nearsightedness and the Importance of Full Vision of Workplace People Over 40 Years Old" published by Ipsos, an internationally renowned research institute, more than 90% of respondents have difficulty reading near distances.

　　On June 21, Aier Ophthalmology announced in Chengdu that it will promote the opening of a presbyopia surgery clinic in the group's refractive surgery department, and use synchronous international corneal laser correction and intraocular lens replacement presbyopia surgery correction technology to lead domestic presbyopia correction. Fully open the "era of mirroring."
