• In regular corneal astigmatism, the refractive power varies successively from one meridian to the next, and each meridian has a uniform curvature.
• In this document, low to moderate refractive errors are defined as spherical equivalents of less than 6.00 diopters (D) of myopia, less than 3.00 D of hyperopia, and less than 3.00 D of regular astigmatism.
• Provision of appropriate spectacles is one of the simplest, most cost-effective strategies to improve vision; therefore, eyeglasses should be considered before contact lenses or refractive surgery.
• Full correction may not be needed for individuals with regular astigmatism.
• Adults with astigmatism may not accept full cylindrical correction in their first pair of eyeglasses or in subsequent eyeglasses if their astigmatism has been only partially corrected.
• In general, substantial changes in axis or power are not well tolerated.
• Although most normal eyes should have a corrected acuity of 20/25 or better, it may not be possible to achieve this level of acuity in patients with high refractive errors, even with optimal refraction.
