Optical correction of refractive error

Optical correction of refractive error refers to clinical methods and technologies used to correct refractive errors—conditions where the eye does not focus light properly onto the retina, resulting in blurred vision[5][1]. Common refractive errors include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia[5][1][6]. Correction approaches include eyeglasses (spectacles), contact lenses, orthokeratology (rigid lenses worn overnight to reshape the cornea), and various forms of refractive surgery (e.g., LASIK, PRK, SMILE), each with its own benefits, limitations, and risks[1][5][6]. These methods do not act on any specific molecular or receptor target, but rather physically alter the optical pathway so that light is correctly focused onto the retina, thus restoring clear vision. Refractive correction is a procedural or device-driven intervention rather than a drug- or molecule-targeted therapy[1][6].
