"content": "Orthokeratology (Ortho-K) lenses are specialized contact lenses designed to temporarily correct myopia by reshaping the cornea overnight. With rising myopia prevalence, especially in Asia-Pacific, the Ortho-K lens market is a critical segment within the vision care industry. The Orthokeratology lens market size is projected to exceed USD 3.2 billion by 2033, reflecting a growth outlook of 12% CAGR during 2026–2033. This industry expansion is fueled by demand for non-surgical vision correction, regulatory advancements, and innovations in lens materials."
