Application‑wise, the RGP market is primarily allocated among keratoconus, astigmatism, and presbyopia treatment, as illustrated in the accompanying pie chart. Keratoconus, a progressive ectasia, drives the largest portion of demand, representing roughly 40 % of the market; clinicians favor RGP lenses for their superior tear‑film stability and corneal reshaping capability, which translates into higher utilization rates. Astigmatism accounts for about 35 % of applications; the rigid design corrects irregular corneal curvature more effectively than soft lenses, leading to sustained prescription renewals. Presbyopia, encompassing roughly 25 % of the market, leverages multifocal RGP designs that provide distance and near vision correction without the bulk of traditional multifocal soft lenses. Each application segment contributes distinct usage patterns and pricing dynamics, collectively shaping the overall market size and informing strategic investment decisions within the RGP Rigid Gas Permeable Contact Lens market.
