    • Apart from testing the eye, they supply booklets detailing eye care with particular reference to refractive errors such as myopia, hypermetropia and astigmatism.
    • Amblyopia can also result from a major difference in the refraction between the two eyes, such as nearsightedness, farsightedness, or astigmatism.
    • Side vision is distorted and oblique rays of light passing through a spherical lens produce astigmatism.
    • It is a surgical treatment for short-sightedness, some forms of long-sightedness and astigmatism and is carried out by ophthalmic surgeons.
    • Most refractive surgical procedures were developed to correct nearsightedness, farsightedness and astigmatism.
    • Corrective lenses such as contact lenses or glasses can usually correct vision in people with astigmatism.
    • Contact lenses can balance the image from both eyes, and correct any irregularities or astigmatism of the eye.
    • In fact about 23% of the lenses sold in Australia are sold to correct astigmatism.
    • People with astigmatism usually need to wear glasses or contact lenses to correct their vision.
    • Toric contact lenses can correct astigmatism for most people.
    • The degree of astigmatism should not exceed more than four diopters.
    • They aren't as effective in correcting some vision problems, including high degrees of astigmatism, as are rigid lenses.
    • In astigmatism, although the eye is perfectly healthy, the cornea is curved more like the surface of an egg, with a steep curve in one meridian and a flatter curve in others.
    • The surfaces of the lens or cornea may not be smooth, causing an aberration that results in a streak of distortion called astigmatism.
    • For lower amounts of astigmatism, often standard lens designs can be used.
    • The glasses do not correct astigmatism, but they are effective against nearsightedness and farsightedness.
    • Suitable for most people who need glasses, including those who are short-sighted, long-sighted or have astigmatism, laser eye surgery treatment is quick, easy and affordable.
    • In astigmatism, the refractive power of the eye is different in different meridians.
    • For pure astigmatism, a lens is required that has no optical power in the normal meridian but has appropriate curvature in the others.
    • Whether myopia, hyperopia or astigmatism is present, surgical correction attempts to redirect light rays to accommodate the refractive error.
