Facts About the Cornea and Corneal Disease | National Eye Institute

Myopia or Nearsightedness is a condition when the distance between the cornea and the retina is too long or the actual shape of the cornea or clear window of the eye is too steep. This causes light images to focus in front of the retina, causing blurry vision in the distance. http://arizonacataract.com/eye-problems/refractive-errors/myopia-nearsightedness/

Hyperopia or Farsightedness is a condition in which the distance between the cornea and the retina is too short or the actual shape of the eye is too flat. This causes light images to focus behind the retina, causing blurred vision. http://arizonacataract.com/eye-problems/refractive-errors/hyperopia-farsightedness/

With astigmatism, the cornea is curved and the image strikes either in front or behind the retinal at different perpendicular plains resulting in distortion of the vision. This is represented in the picture by the stop sign in the middle. Since it misses the retina, the image you see is blurred (the stop sign on the right). http://arizonacataract.com/eye-problems/refractive-errors/astigmatism/
