Refractive errors in eyes result in blurred or distorted vision. It is a set of medical conditions that occur when the eye is unable to focus light properly, preventing clear images from reaching the back of the eye and the brain. Myopia (nearsightedness), hyperopia (farsightedness), presbyopia, and astigmatism are among the most common types of refractive errors. But what’s causing them? Let’s look at some of them below.
Genetics plays an important role in eyesight development, as well as whether you’ll be diagnosed with a refractive error or not. If one or both of your parents can’t discern objects from near or far away, there’s also a chance that your eyes will be the same.
As we age, our eyes naturally become less capable of focusing light and creating a clear image on the retina. Astigmatism, for example, is a common condition for people 40 years or older. Here, the lens of the eye becomes less flexible, making it more difficult to read at close range.
Certain medical conditions can lead to refractive errors. Diabetes and high blood pressure, for example, can cause damage to the eyes’ structures, leading to vision problems. Injuries or eye surgeries may also cause changes in the way light is focused on the back of the eye, resulting in blurred vision.
A variety of environmental factors can also contribute to refractive errors. Exposure to UV radiation (sunlight) and long hours spent looking at a computer screen can cause eye strain, which can lead to vision problems if not managed.
A comprehensive eye exam conducted by an experienced optometrist can help detect refractive errors. At Vienna Eyecare Center, we have the tools and expertise to determine if you or your loved one is nearsighted, farsighted, or has astigmatism.
