Astigmatism is a very common eye condition that’s easily corrected by eyeglasses or contact lenses and on some occasions, surgery.
Astigmatism is caused when your eye is not completely round. Because our bodies are not perfect, astigmatism occurs in nearly everybody to some degree but for some, not to the degree that it causes blurring. Your eye is naturally shaped like a sphere. Under normal circumstances, when light enters the eye, it bends evenly, creating a clear picture on the back of your eye. In a person with astigmatism, their eye is shaped more like a football and light entering the eye is bent more in one direction than the other. This causes only part of the picture to be in focus at any given time. Objects at any distance can appear blurry and wavy. For vision problems due to astigmatism, glasses or contact lenses, and sometimes even vision correction surgery are all possible treatments.
People with undetected astigmatism often have blurred vision which can be associated with fatigue and eyestrain. While these symptoms may not necessarily be the result of astigmatism, you should schedule an eye exam if you are experiencing one or more symptoms.
Astigmatism and Low Vision
People who have astigmatism typically experience blurry vision as one of the primary symptoms. Should the blurriness persist or get worse, it may interfere with everyday activities like driving a car, running errands, preparing meals, or using a computer. Astigmatism is easily corrected with eyeglasses or contact lenses. Sometimes, surgery may be recommended.
Generally, astigmatism is correctable with prescription lenses. However, the conditions resulting in low vision can’t be corrected with glasses or contacts. Once a loss of vision has occurred, it can’t be restored.
