Astigmatism occurs when the shape of your cornea is not as it should be. And because of that, your vision can become blurry or wavy. Unlike with nearsightedness or farsightedness, the effect on your vision is up close, far away, and in-between. Fortunately, here at EyeCare Associates of San Bernardino eye doctor in Riverside CA, the solution is simple and effective: a prescription for eyeglasses or contact lenses.
Your cornea should be round. That’s its normal shape. When it is instead shaped more like a spoon, the result is astigmatism. You can only focus on a portion of what you’re looking at because light is being refracted in an imbalanced way, favoring one side over the other. What is responsible for the change in your corneal shape that leads to astigmatism? Heredity is a common cause. Astigmatism may even be present at birth. Or pressure on your eyelids or corneas, looking too long at things up close, and even improper posture are all possible reasons. Our eye doctor in Riverside CA will diagnose astigmatism as part of a regular yearly eye exam, even if you have not noticed any signs of it. However, if you do experience symptoms such as headaches, eye fatigue or strain, or blurry vision, you may have astigmatism and it’s a good idea not to wait until your annual visit. Typically, you will have either nearsightedness or farsightedness (or both) in addition to astigmatism. Our eye doctor in Riverside CA will prescribe the applicable corrective lenses, which may be bifocal or trifocal depending on your needs. Your vision will be clearer, but you may need to have the prescription adjusted periodically in order to account for changes in how astigmatism is affecting you.
You can always depend on our eye doctor in Riverside CA to diagnose and treat your astigmatism. Why not call us right now and set up a convenient time to come in?
