Treatment & Types of Refractive Error in Karnataka
Corrective eyeglasses or contact lenses precisely matched to the individual's refractive prescription are the standard first-line treatment. Refractive surgery such as LASIK or PRK can permanently reshape the cornea to correct vision for those seeking to reduce dependence on glasses. Orthokeratology and specialty contact lenses are also increasingly used, particularly to slow myopia progression in children.
The four main types of refractive error are myopia (nearsightedness), where distant objects appear blurred because the eyeball is too long relative to its focusing power; hyperopia (farsightedness), where near objects appear blurred because the eyeball is too short; astigmatism, causing blurred vision at all distances due to an irregularly shaped cornea; and presbyopia, the natural age-related loss of the lens's ability to focus on near objects, which affects nearly everyone after around age 40. These types often occur in combination, such as astigmatism alongside myopia, rather than in isolation.
