Myopia or Nearsightedness
Myopia, which is also called nearsightedness, is a common vision problem that is found in approximately one-third of the world's population. Myopia is a refractive problem of the eye that is characterized by light focusing in front of the Retina and thus blurring objects that are far away. People who are nearsighted are able to see objects that are close to them but are unable to see objects at a distance. With myopia, the eyeball is too long, or the cornea is too steep, resulting in images being focused in front of the Retina. Blurred vision from myopia can be treated with eyeglasses or contact lenses or it can be corrected with Laser Eye Surgery for Laser Vision Correction.
Hyperopia or Farsightedness
Hyperopia, which is also called farsightedness, is a common vision problem that causes people to experience blurred vision. Hyperopia is a refractive problem of the eye that is characterized by light focusing in back of the Retina and thus blurring objects that are up close. People who are farsighted are able to see objects that are at a distance to them but are unable to see objects up close. However, if the hyperopia is considerable, it is possible that the condition will blur vision at both near and far distance. With hyperopia, the eyeball is too short, or the cornea is too flat, resulting in images being focused in back of the Retina. Blurred vision from hyperopia can be treated with eyeglasses or contact lenses or it can be corrected with Laser Eye Surgery for Laser Vision Correction.
Astigmatism
Astigmatism is the result of having a corneal surface that is not regular in shape. The eye is unable to focus clearly at any distance because of this irregular focusing surface. Individuals with no astigmatism have corneas that are shaped like basketballs while individuals with astigmatism have corneas that are shaped more like footballs. There are many possible types of astigmatic corneas, which is why the doctor must examine your eyes. People with astigmatism also are often myopic or hyperopic. Blurred vision from astigmatism can be treated with eyeglasses or contact lenses or it can be corrected with Laser Eye Surgery for Laser Vision Correction.
