Near sighted and far sighted are often terms used to describe issues with sight. But, you may wonder what each of these terms mean, specifically, as well as what the difference is between each of them. Here, we will explore the difference between near sightedness and far sightedness, and let you know more about the treatments that are often used to help both issues.
Near Sightedness
Near sightedness is known by the medical term myopia. Objects that are far away are much harder for patients diagnosed with near sightedness to see. Usually, though, their near distance vision is fairly good, hence the name. This condition can be caused because of several issues, but, basically, it means that light allowed into the eye focuses just in front of the retina, instead of directly onto it. In many patients, a family history of the disease may be present. Although other studies have also shown interesting correlation between near sightedness and intelligence quotient, educational attainment, how avid a reader a patient is, and more. Really, there is no way to prevent myopia, nor is there really any way to slow its advancement over time.
Far Sightedness
Far sightedness may be known by its medical name, hyperopia. This term is used to describe the fact that patients with this issue may find it much easier to see objects that are very close to their face. It can, however, just cause it to be difficult to focus on all objects, no matter the distance. The reason many people are far sighted is because one or both of their eyes happen to be a bit misshapen in some way. Due to this slight defect, images that these patients see focus behind the retina. Usually, this condition is also genetic.
Treatment for Both
Both of these issues are most often treated by the prescription of corrective lenses, whether that be in the form of glasses or contact lenses. A visit to an optometrists for a vision examination can tell you whether or not you are either far sighted or near sighted. If you experience blurred vision at any distance, difficulty seeing, headaches, and more, you may want to make an appointment with your local optometrist. They can write you a prescription which you can take to an optician in order to get the type of corrective lenses that you need to at least help you to see better.
