Hyperopia (or farsightedness)
Hyperopia or farsightedness is the opposite of myopia wherein the image is focused on a point beyond the retina. The unfocused image captured by the retina is then sent to the brain and processed as an unclear picture.
This condition is a result of an eye that is too short or a cornea that lacks the necessary refractive power to focus images on the retina. Here all images are blurred, but especially the near objects.
You are long-sighted when your spectacle prescription shows a plus sign in front of the number in the ‘sph’ box.
