A slight deviation in the shape of the cornea can change the refraction or the way light enters the eye. The American Academy of Ophthalmology estimates that approximately 1 in 3 people have astigmia, and it may occur along with other refractive errors. Detection of the difference between a normal cornea shape and an irregular one allows an optometrist to assess the extent of refraction error. Prescription glasses or contact lenses can correct it.
Even though the condition occurs widely across the population, medical science does not explain why the shape of a cornea may differ from one person to another. However, evidence exists that the likelihood of developing it points to an inherited trait that families share. Therefore, myths that claim it can result from watching the television closely or reading in low light have no merit.
Astigmatism presents signs that may not confirm its existence, but it can create inconveniences that deserve investigation of conditions that cause them. As a frequently reported complaint, blurry vision ranks high as a likely indicator, and areas of distorted vision may deliver a clue as well. Other indications of the condition contribute to the need for an eye examination.
While eyes that feel dry, sore, tired, burning, or watery may cause eyestrain, each condition causes discomfort that needs relief. They serve as reliable indicators but not a diagnosis. As one of many symptoms, each can help an optometrist provide a diagnosis and treatment.
Pain in a specific area of the head or generalized discomfort may indicate the presence of a common refraction error. As symptoms that get immediate attention, headaches may contribute to a decision to investigate the cause.
Partly closing the eyes seems to help some people see more clearly, and it may provide a temporary approach to solving a long-lasting problem. As one of the more apparent signs, squinting deserves attention when it becomes a frequent option in trying to improve vision.
Adults can note and track the signs of astigmatism as they occur more frequently as the condition worsens, an advantage that most children do not have.
Objects that appear blurry can affect a child’s learning and sports activities, but they may not realize or identify it as a problem. Therefore, when a child squints or covers one eye while reading, watching T.V., or looking at almost anything, it may indicate a vision problem. A series of eye exams with an optometrist at regular intervals can detect eye disease. Some newborns have astigmia that may resolve itself, but it may continue. From an initial check through the school years, children need a vision check every year to address the causes that symptoms present.
While a child may not express a problem with seeing clearly, a practice of bringing an iPad or book closer than usual can mean something needs investigating. Even though the behavior may not include a sound, it represents a cry for help.
Anyone who does not have astigmatism may not realize the difficulties it creates in everyday functions. Glare poses a specific challenge to an astigmatic condition that makes seeing ordinary objects difficult.
Without realizing the significance of a simple act, children who rub their eyes frequently may send a signal that a problem with vision exists. Unfortunately, they may not understand the delicate nature of the eye and may rub too hard. An eye exam can prevent the occurrence and relieve parents’ concerns.
While almost everyone has the condition to some extent, glasses or contact lenses can provide vision correction.
