  1. Differences among myopes, emmetropes, and hyperopes by Valerie J Gawron, 1980

41. Hyperopia
A condition of the eye that most commonly results in blurred close vision.

Hyperopia (Farsightedness)
A condition of the eye that most commonly results in blurred close vision, although moderate to severe hyperopia may also result in blurred distance vision. The cornea and lens focus light rays from objects behind, rather than directly on, the retina. Corrective Options Available for Hyperopia
  • Corrective Lenses (glasses): Eyeglasses are, of course, the classic way to correct vision problems. They've been helping those problems since the 13th century. Contact Lenses : Contact lenses are delicately crafted, very thin optical discs generally smaller than a dime, worn directly on the eye. They are comfortably held in place by a natural layer of tears present between the contact lens and the cornea. Contacts eliminate the barriers encountered with spectacles that interfere with the line of sight above, below and to the sides of the eye, offering outstanding peripheral vision. In addition, contacts can reduce or eliminate the image distortion sometimes caused by eyeglasses. Source: Contact Lens Council Alcon makes lenses comfortable and lens care easy LASIK : LASIK is a refractive surgical procedure to help correct vision problems. The term LASIK is an abbreviation or acronym for laser-assisted in-situ keratomileusis, which means "to reshape the cornea, from within, using a laser."

Hyperopia, or farsightedness, is the opposite of myopia. Distant objects are clear, and close-up objects appear blurry. This condition is a result of a eye that is too short or a cornea that lacks the necessary refractive power to focus images on the retina.
If you have hyperopia, images focus on a point beyond the retina. This unfocused image captured by the retina is then sent to the brain and processed as an unclear picture.

Hyperopia
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.) Definition
Hyperopia (farsightedness) is the condition of the eye where incoming rays of light reach the retina before they converge into a focused image. Description
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.

What is farsightedness?
Farsightedness (hyperopia) results when structural defects in the eye cause your vision to be blurry. If you are farsighted, you see distant objects more clearly than close objects, though both near and distant vision may be affected, and you may have trouble focusing when performing tasks such as reading or sewing. Although these defects (such as a shorter eyeball or a flat cornea) are often present early in life, normal development and lengthening of the eyeball during early childhood usually corrects the condition. As you age, your eyes lose the ability to change the shape of the lens to focus on near objects (

Refractive error exists when light does not focus perfectly onto the retina. Almost everyone has some degree of refractive error, whether they know it or not. The three types of refractive error are myopia, hyperopia, and astigmatism. These are all in contrast to “emmetropia”, which is the complete absence of refractive error. Emmetropes see clearly far away without needing to exert focus. Myopia or “nearsightedness”. Patients with myopia, both young and old, see more clearly up close than far away.
Hyperopia or “farsightedness”. In hyperopia, it is more comfortable to see far away than up close. Youngsters can often compensate for hyperopia by kicking in extra focusing effort (often without knowing) to clear objects at all distances. Unlike emmetropes, hyperopes must exert effort just to see clearly far away. While emmetropes need to expend effort to see clearly at near, hyperopes need to exert even more effort to see clearly at near.

What is Hyperopia?
Hyperopia or farsightedness is a very common refractive disorder, affecting up to 62% of people over the age of 40. With hyperopia, you may see objects that are far away, but have difficulty focusing on near objects. You may also find that you can see things clearly, but have to strain your eyes to maintain focus.
Hyperopia occurs when the eyeball is too short or the cornea is too flat. When light enters a hyperopic (short) eyeball, it is focused behind the retina instead of directly on the retina where light must be directed for normal vision. Because of this, the focusing apparatus of the eye must constantly work to compensate and focus images.
Symptoms and options
Symptoms of hyperopia include blurred vision, eyestrain or headaches (especially when reading or at the end of the day). They will increase over time. Doctors prescribe a "plus" or convex corrective lens, in the form of eyeglasses or contacts, for the disorder. Hyperopia can also be corrected by steepening the central cornea using a vision procedure such as laser surgery or NearVision CK (Conductive Keratoplasty

Farsightedness
Introduction to Farsightedness About 1 in 4 people in the U.S. have hyperopia or farsightedness, but fortunately there are more ways to correct this eye disorder than ever before. People with hyperopia or farsightedness have difficulty focusing on objects close up, such as print in a book. More severe hyperopia would also cause problems with seeing objects in the distance clearly, such as highway signs. The occurrence of hyperopia increases with age; At least half of all persons over the age of 65 have some degree of farsightedness. What Causes It? Hyperopia is a refractive error, like astigmatism and nearsightedness (myopia). Having a refractive error means that light rays bend incorrectly into your eye to transmit images to the brain. Farsightedness occurs when light entering the eye focuses behind the retina, instead of directly on it. An abnormally flat cornea or short eye can cause the light to enter the eye this way. Hyperopia often runs in families. It is often present at birth; however, many children outgrow it.
