Astigmatism is the result of a misshaped cornea. And in that way, it is not that different from nearsightedness and farsightedness. The effects of this refractive condition can be counteracted with eyeglasses or contact lenses prescribed by our eye specialist in San Diego, Kelly S. Keefe, MD.
Corneas are basically shaped like a spoon; not quite round, but roundish. When the cornea loses its shape to resemble a cone, that is when you end up with astigmatism. Light is refracted more in one direction than in another, and you find that your vision is blurry or wavy, not just up close or far away, but at all distances. The cause may be at least partially hereditary. In fact, some people are actually born with astigmatism. In addition, pressure on your eyelids or corneas, such as when you look at things up close for too long, as well as improper posture can all contribute to the development of astigmatism. Our eye specialist can diagnose it as part of a routine yearly eye exam, which is recommended for all adults. You may also experience signs, which in addition to blurry or wavy vision, include eye fatigue or strain, and headaches. In that instance, you should not wait for an annual checkup. Astigmatism may be the only refractive issue you have, but it is often accompanied by nearsightedness and/or farsightedness. After being examined by our eye specialist in San Diego, you’ll get the prescription that you you need, which may be bifocal or trifocal. Each year thereafter, however, you should come back to have your vision screened again. Changes to your cornea over time might cause you to need an adjustment to your prescription in order to maintain the highest level of vision that you are capable of.
