Nearsightedness and farsightedness are two of the most common types of eye problems you may have encountered. However, you are not alone if you are unsure what the difference between them is, or what the phrases even mean at all! If you think you may have eye problems, be sure to schedule an eye exam at your earliest convenience. In the meantime, read on for some clarity on this issue.
Being farsighted is a condition medically known as hyperopia. People with this condition can see distant objects very well, but have difficulty focusing on objects that are up close. This occurs when your eye is too short lengthwise and does not bend the light that enters it correctly. Similarly, it also happens if one of your corneas is not sufficiently curved. This causes an image to focus behind the retina instead of directly on it, so the image is blurry. People with hyperopia commonly have problems with viewing menus, books, maps, games, or computer screens that are placed too close.
Being nearsighted is a condition medically known as myopia. This is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry. People who are nearsighted may have headaches or eye strain and might squint or feel fatigued when driving or playing sports. While someone who is nearsighted may be able to see his or her friend across the table perfectly well, they may have trouble recognizing faces from across an office or college quad. The condition itself stems from an eyeball that is longer back to front than normal, or an overly curved cornea. This change in eyeball shape means light doesn't hit the retina directly, but a point in front of it.
