MAIN SEARCH INDEX Hyperopia Definition Description Causes and symptoms Diagnosis ... Resources 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.

Health Center Dictionary Encyclopedia Innovation Spotlight ... Eye Care Library Encyclopedia - Hyperopia (Farsightedness) How does the eye see? What causes hyperopia? How is hyperopia corrected? Hyperopia is the ability of the eye to clearly see objects at a distance but not up close. For instance, a person who is farsighted can see to drive, but needs corrective lenses for reading. How does the eye see? The eye functions much like a camera with two lenses. The first lens is the cornea , a clear membrane that covers the front of the eye. The second lens is the eye's natural crystalline lens, which is located behind the pupil. The cornea is responsible for about 70 percent of the eye's focusing power, while the natural lens "fine-tunes" the image before it is focused on the retina at the back of the eye. The retina works like the film in a camera, receiving light images and sending them through the optic nerve to the brain. ( See Anatomy of the Eye. ) If both lenses are working properly, the image is focused precisely on the surface of the retina. What causes hyperopia?

Hyperopia Information hyperopia, occurs when light entering the eye focuses behind the retina, instead of directly on it. This is caused by a cornea that is flatter, or an eye that is shorter, than a normal eye. Farsighted people usually have trouble seeing up close, but may also have difficulty seeing far away as well. Hyperopia, also known as farsightedness, is usually inherited. Children are often hyperopic which may lessen as an adult. Hyperopia is a refractive error, which results from a disorder rather than from disease. A refractive error means that the shape of your eye does not bend light correctly, resulting in a blurred image. Common vision screenings, often done in schools, are generally ineffective in detecting farsightedness. A comprehensive optometric examination will include testing for farsightedness. In mild cases of farsightedness, your eyes may be able to compensate without corrective lenses. In other cases, your optometrist can prescribe eyeglasses or contact lenses to optically correct farsightedness by altering the way the light enters your eyes.

Typically the near vision is blurred and distance vision is good. Hyperopic eyes are shorter in the axial length and many corneas are flatter. There are many treatment options including spectacles, contact lenses, and recently FDA approved refractive surgery.

What is Hyperopia? In the normal eye, light bends through the cornea and lens to focus on the retina. With hyperopia (farsightedness - place cursor over image) the eye is shorter (or cornea is flatter) causing the focal point of light to be behind the retina. The image is therefore out of focus on the retina and vision is blurred. Place Cursor Over Image. The Treatment 1. A thin flap of cornea is created and folded back. 2. Excimer laser is applied to reshape (ablate) the cornea. 3. The corneal flap is replaced over the treated cornea. 4. The "steeper" cornea now bends light to become focused on the retina. LASIK for Hyperopia Animation The Result Before LASIK treatment, light is out of focus on the retina. After LASIK treatment (place cursor over image), the "steeper" cornea (arrow) causes light to bend in such a way as to become focused on the retina. Vision is clear. Place Cursor Over Image. Laser in-SItu Keratomileusis (LASIK) can be used to treat low to high levels of farsightedness (hyperopia) with the goal of reducing or eliminating dependence on corrective lenses. Farsightedness occurs when the cornea is too flat or the eye is too short. This causes the focal point of light to fall behind the retina, rather than on the retina, resulting in blurry near vision. LASIK uses the computer-controlled precision of the Excimer laser to treat the inner tissue of the cornea. The procedure is done using eye drop anesthesia, and while you may feel pressure, the technique is not painful. First, an instrument known as a microkeratome makes a protective flap in the outer layer of the cornea. Next, the Excimer laser sculpts the internal corneal tissue to the correct refractive power by steepening the curvature of the exposed corneal tissue. The "steeper" cornea allows light rays to focus more directly on the retina, thereby reducing farsightedness. After a few minutes of drying, the corneal flap is laid back in its original position. Due to the cornea's extraordinary natural bonding qualities, the flap seals without sutures within 2-5 minutes.

DOCTORS LOCATIONS THE EYE VISION CORRECTION ... LINKS AND CREDITS Hyperopia (Far Sightedness) Hyperopia is also known as "farsigtedness." It usually means that one has better distant vision than near vision. It is very common. In fact, the majority of the United States population is farsighted. Hyperopia tends to mostly affect the young under 10 years old and people age 45 and above. The condition is characterized by an eye that is too short in length, or where the front of the corneal curvature is too weak. The eye has three components that determine focusing behavior. The first and strongest component is the cornea. It is the clear part of the eye on the front surface. It's responsible for between 70% and 80% of focus in the eye. The second focusing component of the eye is the lens. It's located inside the eye behind the cornea. It is responsible for bending, or focusing, the light 20%-30%. The third component in light focusing is the length of the eye. It is the least significant factor. If the eye is too short, it can cause farsightedness. If the eye is too long, it can cause nearsightedness (myopia) Most people can automatically compensate for their hyperopia by focusing more with their lens. However, this constant compensation often causes difficulty in reading or computer work. This is termed "eye strain" and can be relieved with lenses to compensate for the hyperopia.

Smith Eye Care Hyperopia Farsightedness, or hyperopia , as it is medically termed, is a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus. Farsightedness occurs if your eyeball is too short or the cornea has too little curvature, so light entering your eye is not focused correctly. Common signs of farsightedness include difficulty in concentrating and maintaining a clear focus on near objects, eye strain, fatigue and/or headaches after close work, aching or burning eyes, irritability or nervousness after sustained concentration. Common vision screenings, often done in schools, are generally ineffective in detecting farsightedness. A comprehensive eye examination will include testing for farsightedness. In mild cases of farsightedness, your eyes may be able to compensate without corrective lenses.

Hyperopia (farsightedness) or the focusing power of the cornea and lens being too weak to focus light on the retina (back of the eye which acts like film in a camera). The result is near vision being worse than distance vision. Hyperopia can be present at any age, and is different from presbyopia which occurs over age 40. In young patients with mild to moderate degrees of hyperopia distance vision is typically good, but the patient may experience headaches or eyestrain when reading. Higher degrees of hyperopia may blur distance vision also, and may lead to amblyopia (lazy eye). School vision screenings may often fail to detect hyperopia because they only test distance vision. Hyperopia can be corrected with eyeglasses or contact lenses. Back

Farsightedness or hyperopia If you are farsighted, you are able to see objects at a far distance clearly whereas objects at a close distance appear blurry. Compared to the eye with normal vision, your eye has grown too short. The refractive point of incoming light rays is not located on the retina itself but behind it. The optical correction is made by increasing the refractive power of your eye, in other words by moving the refractive point forward. For eyeglasses and contact lenses , the correction is made with a convex lens, and the corrective value is indicated in "plus" diopter. Your prescription will read for example +3.5 diopter. If surgery is performed, the refractive power of the cornea or of the lens is altered in such a way that it reaches optimal conditions. The farsighted eye differs from the nearsighted eye insofar as up to a certain age, farsightedness can be accommodated by the lens of the eye. The lens of the eye is able to change shape (accommodation) and thereby increases its refractive power, which compensates for the decreased refractive power of the farsighted eye for distance vision. Farsighted individuals usually are able to see images at a distance well even at advanced ages. Eyeglasses for younger people are needed only in severe cases of farsightedness.

What is Hyperopia? Hyperopia or farsightedness is a very common refractive disorder, affecting 27% of the non-Asian population. (Note: Hyperopia occurs at a much lower level in the Asian population.) 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 Correction Symptoms of hyperopia include blurred vision, eyestrain, or headache (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 Conductive Keratoplasty SM (CK).

Hyperopia What is farsightedness? Farsightedness, or hyperopia, as it is medically termed, is a vision condition in which distant objects are usually seen clearly but close ones are not brought into proper focus. Why does farsightedness occur? If the length of your eyeball is too short or the cornea has too little curvature, near objects cannot be brought into a sharp and clearly focused image. Some theorists believe that farsightedness is hereditary and others believe that it may result from environmental factors. How does farsightedness affect vision? If you are farsighted, you involuntarily exert extra effort to maintain clear distance vision and even greater effort to see clearly at close range. This extra effort can cause fatigue, tension and discomfort. If the crystalline lens of the eye cannot bring the object into focus, blurred vision occurs. How common is farsightedness? Many people have some degree of farsightedness. The condition is only a problem if it significantly affects a person's ability to see. It is estimated that over half the people who wear glasses are wearing them because of a focusing problem due to farsightedness or presbyopia, a natural decrease in focusing ability. What are signs/symptoms of farsightedness?
