The 11 pages that link to Astigmatism, each with the reason it gives.

• Contact lensBroader topic: Toric contact lenses provide different powers across meridians to correct it.

• Refractive errorBroader topic: It creates directional blur rather than one uniform focal point.

• MyopiaCompared with: Astigmatism arises from direction-dependent focusing, unlike myopia’s principal distance-focus error.

• EyeglassesRelated: Cylindrical eyeglass power compensates for the eye’s direction-dependent focusing.

• AccommodationCompared with: Accommodation changes overall lens power but does not correct unequal meridional focus.

• PresbyopiaCompared with: It blurs vision at multiple distances, unlike presbyopia’s characteristic near-focus decline.

• LASIKBroader topic: LASIK can reshape meridians differently to reduce this irregular focusing.

• OptometryBroader topic: Its distinct optical pattern requires correction beyond simple spherical lens power.

• EyeBroader topic: Uneven corneal or lens curvature prevents a single sharp focus.

• Blurred visionBroader topic: Irregular optical curvature can blur or distort objects across the visual field.

• Bates methodBroader topic: This structural optical difference cannot be corrected by the relaxation practices Bates proposed.
