Children may be even more unaware of the condition than adults, and they are unlikely to complain of the blurred or distorted vision. Unfortunately, astigmatism can affect their ability to see well in school and during sports, so it’s important to have their eyes examined at regular intervals in order to detect any astigmatism early on.
In regular astigmatism, the meridians in which the two different curves lie are located 180 degrees apart. In irregular astigmatism, the two meridians may be located at something other than 180 degrees apart; or there are more than two meridians.
Regular astigmatism is usually easy to correct (see treatments below), but irregular astigmatism can be complicated and more difficult to correct, depending on the extent of the irregularity and its cause.
Usually astigmatism is hereditary: many people are born with an oblong cornea, and the resulting vision problem may get worse over time. But astigmatism may also result from an eye injury that has caused scarring on the cornea, from certain types of eye surgery, or from keratoconus, a disease that causes a gradual thinning of the cornea.
Many people with astigmatism believe that they can’t wear contact lenses, or that only rigid gas permeable contact lenses can correct astigmatism. This was true many years ago, but now there are soft contacts that correct astigmatism; they are called toric contact lenses.
Toric lenses have a special correction built into them and may also contain a prescription for nearsightedness or farsightedness if you need it. While soft torics work well for many people, if you have severe astigmatism, you’ll likely do better with Rigid Gas Permeable contact lenses or spectacles. At Ezekiel Eyes we can advise you.
