Astigmatism is one of the most common vision conditions; most people have some form of astigmatism. Astigmatism can be caused by an irregular shaped cornea or curvature of the lens, and can lead to blurred vision.
Minor astigmatism may not affect your vision or require treatment. However, many cases lead to blurred or distorted vision, which can result in pain and headaches. Typically, astigmatism is present with nearsightedness and farsightedness. These conditions are described as refractive errors.
Our examinations test for astigmatism using a phoropter and retinoscope, which measure refraction. Depending on the amount of astigmatism, we can provide eyeglasses or contact lenses to help correct your condition. A wide range of other solutions may be available and our optometrists will discuss your options during your consultation.
Farsightedness, known as hyperopia, makes it difficult to see objects that are close and is caused when images are focused behind the retina. This can be a result of the eye being too small. 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 and is caused when images are focused in front of the retina. This typically occurs when the eyeball becomes longer, which is common in children who are growing quickly. The changes may be frequent, and glasses or contact lenses may need to be updated often.
