Treating Refractive Errors For Patients From All Over Chapel Hill, NC & Surrounding Areas

The eye itself is an amazing structure, with many parts that each contribute to forming a clear image for us to enjoy. If the light rays do not come to a perfect focus on the retina, you have a refractive error. According to The International Agency for the Prevention of Blindness (IAPB), refractive errors are very common affecting more than 123 million people. 

Common refractive errors include:
  • Hyperopia (Farsightedness): Light rays come to focus behind the retina, causing vision to be blurry, often at both, near and far distances. This is typically caused by having a cornea that is too flat.
  • Myopia (Nearsightedness): Light rays come to focus in front of the retina, causing vision to be blurry, more so at a distance. This is typically caused by having a cornea that is too steeply curved.
  • Astigmatism: Light rays come to focus at multiple points on the retina, causing vision to be blurry, often at both, near and far distances. This is typically caused by an irregular curvature of the cornea.
  • Presbyopia: The lens fails to change shape with age, resulting in difficulty focusing on near objects.
