Addressing Refractive Errors: Myopia Glasses, Hyperopia Glasses, and Astigmatism Glasses
The core function of optical glasses is the correction of refractive errors. The three most common types of these errors—myopia (nearsightedness), hyperopia (farsightedness), and astigmatism—are the primary drivers of demand for prescription glasses [12†L12-L13]. The refractive errors segment alone is forecasted to dominate the global vision care market with a 33.3% share in 2026 [12†L12-L13].
Myopia, in particular, has reached epidemic proportions globally. Data from 2026 indicates that 30–35% of adults worldwide are myopic [17†L20-L21]. The situation is even more severe in East Asia, where urban centers report that over 80% of adolescents are nearsighted by the time they finish high school [17†L21-L23]. Globally, one in three children now has myopia, and if current trends continue, there will be more than 740 million pediatric cases by 2050 [18†L5-L7]. This surge in myopia, especially among younger populations, is creating an urgent need for specialized myopia glasses. At the 2026 Canton Fair, buyers can expect to see a wide range of myopia glasses, including single-vision lenses for simple correction and advanced myopia management lenses designed to slow progression in children.
While myopia captures headlines, the market for hyperopia glasses remains substantial, particularly in aging populations where the lens of the eye loses flexibility. Furthermore, astigmatism is a widespread condition that often coexists with myopia or hyperopia. Astigmatism affects an estimated 40% of adults and 15% of children worldwide, yet it often goes undiagnosed [21†L10-L13]. Astigmatism glasses utilize cylindrical lenses to correct the uneven curvature of the cornea, providing clear and sharp vision. The 2026 Canton Fair will feature a vast array of astigmatism glasses, from entry-level options to high-precision toric lenses manufactured by China's leading optical labs.
The Chinese Manufacturing Advantage: Danyang and Beyond
China is the undisputed global powerhouse for optical glasses manufacturing.
