What is the prevalence of High Myopia?
How many people does High Myopia affect? Does it have the same prevalence in men and women? And in the different countries?
The prevalence of High Myopia, also known as severe nearsightedness, varies across different populations. However, it is estimated that around 2-3% of the global population is affected by this condition. High Myopia is characterized by a refractive error of -6.00 diopters or more, indicating significant difficulty in seeing distant objects clearly. It can lead to various complications, including retinal detachment, glaucoma, and macular degeneration. Regular eye examinations and early intervention are crucial in managing and preventing potential vision problems associated with High Myopia.
High Myopia refers to a severe form of nearsightedness where individuals have a significantly high degree of myopia, typically exceeding -6.00 diopters. It is a condition characterized by elongated eyeballs, which causes light to focus in front of the retina instead of directly on it, resulting in blurred distance vision.
Estimating the prevalence of High Myopia can vary across different populations and regions. However, studies suggest that its occurrence is increasing globally. In some East Asian countries, such as China, Singapore, and Taiwan, the prevalence of High Myopia among young adults has reached alarming levels, affecting around 20-30% of the population.
Furthermore, research indicates that genetic factors play a significant role in the development of High Myopia. Individuals with a family history of the condition are more likely to be affected. Additionally, environmental factors like excessive near work, lack of outdoor activities, and prolonged screen time may contribute to its prevalence.
Early detection and appropriate management of High Myopia are crucial to prevent potential complications like retinal detachment, glaucoma, and myopic macular degeneration. Regular eye examinations and the use of corrective measures, such as glasses, contact lenses, or refractive surgery, can help individuals with High Myopia lead a better quality of life.
