Astigmatism is one of the most common vision conditions, and most people have some form of astigmatism. It can be caused by an irregular-shaped cornea or an abnormal curvature of the lens.
Minor astigmatism may not affect your vision or require treatment. However, many cases cause blurred or distorted vision, which can result in pain and headaches. Typically, astigmatism is present with nearsightedness and farsightedness.
During your examination, we test for astigmatism using a phoropter and retinoscope, which both measure refraction.
Depending on the severity of the astigmatism, we can provide eyeglasses or contact lenses to help correct your condition. There is also a wide range of other solutions that may also work for you. We would be happy to discuss your options with you at your appointment.
Farsightedness, known as hyperopia, makes it difficult to see objects that are close. It is caused when the light entering the eye is focused behind the retina instead of on it. This can be a result of the eyeball being too short. Many times, farsightedness occurs at birth. Some children outgrow the condition without experiencing many symptoms.
Nearsightedness, known as myopia, makes it difficult to see objects far away. It is caused when the light entering the eye is focused in front of the retina instead of on it. This typically occurs when the eyeball is elongated, which is common in children who are growing quickly. Changes in your child’s vision may happen often, so it is important for them to continue to visit the eye doctor regularly to update their prescriptions for their glasses or contacts.
