    Extractions: When light goes through transparent but dense material like the materials of the eye's lens system (the lens and cornea), its velocity decreases. If the surface of the dense material is not perpendicular to the incoming light, as is the case with the curved surfaces on lenses and corneas, the direction of the light changes. The greater the curvature of the lens system, the greater the change in the direction of the light. When parallel light rays from an object go through the lens system of the eye, they are bent so they converge at a point some distance behind the lens. With perfect vision this point of convergence, where the light rays are focused, is on the retina. This happens when the cumulative curvature of the lens plus cornea and the distance from the lens to the retina are just right for each other. The condition where the point of focus of parallel light rays from an object is behind the retina is called hyperopia. This condition exists when the combined curvature of the lens and cornea is insufficient (e.g., flatter than needed for the length of the eyeball). This condition can be equivalently described by saying hyperopia exists when the eyeball is too short for the curvature of its lens system.

Causes, incidence, and risk factors Return to top Farsightedness is the result of the visual image being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak. Farsightedness is often present from birth, but children can often tolerate moderate amounts without difficulty and most outgrow the condition. As aging occurs, glasses or contact lenses may be required to correct the vision. A family history of farsightedness is a risk factor.

Surgical techniques are available for correcting farsightedness and can be used for those who do not wish to wear glasses or contacts.

    Extractions: Hyperopia, or farsightedness, is a condition of the eye where incoming rays of light impinge on the retina before converging into a focused image, resulting in difficulty seeing nearby objects clearly. (Illustration by Electronic Illustrators Group.) Hyperopia (farsightedness) is the condition of the eye where incoming rays of light reach the retina before they converge into a focused image. When light goes through transparent but dense material like the materials of the eye's lens system (the lens and cornea), its velocity decreases.

33. USAeyes.org - Hyperopia Difficulties
    I understand that hyperopia is more difficult to correct than myopia. Why? Before presbyopia, the natural lens can somewhat focus around the hyperopia.  
    http://www.usaeyes.org/faq/subjects/hyperopia.htm
    
    Extractions: CONTACT US For a shift in refractive error to reduce myopia , the center of the cornea needs to be flattened. For a shift in refractive power to reduce hyperopia , the center of the cornea needs to be steepened with a "bulge" outward. Think of the old saying, "If you can't raise the bridge, lower the water." Myopic correction raises the bridge. Hyperopic correction lowers the water. As with lowering the water, steepening the cornea is much more difficult. First, I'll describe current techniques in myopic correction: A laser removes tissue in the center of the cornea to make it flatter. That's about it.

If the surface of the dense material is not perpendicular to the incoming light, as is the case with the curved surfaces on lenses and corneas, the direction of the light changes.

The condition where the point of focus of parallel light rays from an object is behind the retina is called hyperopia. This condition exists when the combined curvature of the lens and cornea is insufficient (e.g., flatter than needed for the length of the eyeball). This condition can be equivalently described by saying hyperopia exists when the eyeball is too short for the curvature of its lens system. There is a connection between the focusing of the lens of the eye (accommodation) and convergence of the eyes (the two eyes turning in to point at a close object.) The best example is during reading. The lens accommodates to make the close-up material clear and the eyes turn in to look at the print and keep it single. Because of this connection between accommodation and convergence, if the lens needs to accommodate to focus for distance (to bring the image back onto the retina) the eyes may appear to turn in even when looking at the distance. This can cause a condition known as accommodative esotropia in children. The eyes turn in and the cause is accommodation because of hyperopia.

    hyperopia or FARSIGHTEDNESS. With hyperopia, or Farsightedness, the eye is not powerful enough to focus light rays reflected off viewed objects onto the retina.  
    http://www.youreyesite.com/hyperopia.htm
    
    Extractions: aglazier@youreyesite.com Light rays that are reflected off objects must travel through the refractive elements of the eye and be focused to a point image on the Retina, or back surface of the eye, in order to see clearly. With Hyperopia, or Farsightedness, the eye is not powerful enough to focus light rays reflected off viewed objects onto the retina. The light rays travel to a point focus in imaginary space behind the Retina and the result is a blurred image. People who are farsighted usually have difficulty seeing near objects and in some cases may be so farsighted that distance objects also appear blurry.
