Refractive Errors - Hyperopia - VisionChannel hyperopia, or farsightedness, is a disorder where distant objects are usually seen clearly, but close ones do not come into proper focus and are blurred. http://www.visionchannel.net/refractiveerrors/hyperopia.shtml
Extractions: Hyperopia Hyperopia, or farsightedness, is a disorder where distant objects are usually seen clearly, but close ones do not come into proper focus and are blurred. This occurs when the eyeball is too short or the cornea is too flat, and light rays entering the eye focus behind the retina rather than directly on it. Hyperopia is often present at birth, but sometimes, vision normalizes as the eyeball lengthens during the growth process. Young adults and children with mild to moderate cases of farsightedness often see close objects clearly because the lens is able to adjust or change its shape. This process is called
Extractions: What is hyperopia? Hyperopia (far-sightedness), myopia (near-sightedness), and astigmatism (distorted vision) are what as know as refractive errors. For proper eyesight, the cornea (the clear window in front of the eye) and the lens (behind the pupil) must properly focus or "refract" light onto the retina (at the back of the eye). If the length or shape of the eye is not ideal, the light may get focused too early or too late leaving a blurred image on the retina. Hyperopia, or far-sightedness, is the ability to clearly see objects at a distance but not those up close. Causes and symptoms Like near-sightedness, far-sightedness is usually an inherited condition. Young children tend to be hyperopic to some degree although the severity lessens and they age and the eye grows and becomes longer. Children with far-sightedness can often see both distant and close objects because the youthful strength of their lenses can often overcome the shortness of the eye. Non-visual signs such as headaches or a lack of interest in reading may be signs of a high degree of hyperopia. Treatment Treatment is not necessary for children with a small amount of hyperopia where no symptoms are evident. Those with more severe cases or crossed eyes are best treated with eyeglasses or contact lenses.

The Physics Classroom Farsightedness or hyperopia is the inability of the eye to focus on nearby objects. The farsighted eye has no difficulty viewing distant objects. http://www.physicsclassroom.com/Class/refrn/U14L6d.html
Extractions: Physics Tutorial Refraction and the Ray Model of Light Lesson 1 Lesson 2 ... Nearsightedness and its Correction The human eye's ability to accommodate allows it to view focused images of both nearby and distant objects. As mentioned earlier in Lesson 6 , the lens of the eye assumes a large curvature (short focal length) to bring nearby objects into focus and a flatter shape (long focal length) to bring a distant object into focus. Unfortunately, the eye's inability to a provide a wide variance in focal length leads to a variety of vision defects. Most often, the defect occurs at one end of the spectrum - either the inability to assume a short focal length and focus on nearby objects or the inability to assume a long focal length and thus focus on distant objects. Farsightedness or hyperopia The cure for the farsighted eye centers around assisting the lens in refracting the light. Since the lens can no longer assume the convex and highly curved shape which is required to view nearby objects, it needs some help. Thus, the farsighted eye is assisted by the use of a converging lens. This converging lens will refract light before it enters the eye and subsequently decreases the image distance. By improving the refracting ability of the eye, the image of nearby objects is once again focused upon the retinal surface.

Extractions: 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 hyperopia, or farsightedness, is a common eye condition. hyperopia occurs when the light that enters the eye focuses behind the retina. http://www.penneye.com/html/hyperopia.html
Extractions: Search: PENN Eye Care Philanthropy Hyperopia, or farsightedness, is a common eye condition. Hyperopia occurs when the light that enters the eye focuses behind the retina . In many cases, the eyeball is to short and so the focal point of light falls behind the retina. The retina is analogous to photographic film in a camera and is located at the back of the eye. People with hyperopia are called farsighted because, in many cases, they can see far away but not up close. In reality, however, the situation is much more complicated. Young hyperopic individuals may be able to see well at all distances and not even know they are hyperopic because the lens of the eye can accommodate. In other words, the eye can compensate for modest amounts of hyperopia. However, this ability to compensate is lost with age and so hyperopia is often discovered as that person ages. People with hyperopia are at higher risk for certain types of eye conditions, including certain forms of glaucoma Hyperopia can usually be treated with glasses, contacts , or r efractive surgery
Hyperopia » Optometrists Association Australia hyperopia. What is hyperopia? The eye s lens and cornea focus light How does hyperopia affect vision? A little hyperopia is not a problem http://www.optometrists.asn.au/eyevision/disorders/referrors/hyperopia
Extractions: Home The Association State Divisions National Council ... Refractive errors What is hyperopia? The eye's lens and cornea focus light into an image on the retina, just as a camera lens focuses light on to a film. In a resting hyperopic (longsighted) eye, the light is focused behind the retina and so the image is blurred. The perfect state of focusing exactly on the retina is unusual; the average person is a little hyperopic. How does hyperopia affect vision? A little hyperopia is not a problem because the lens compensates easily but if there is a significant amount of hyperopia, the effort of focusing (called accommodation) can lead to symptoms. A hyperopic person can have normal vision but the greater the hyperopia, the harder it is to focus. Vision may become blurry, especially for close objects, because the closer the object the more focusing is required. Hyperopic people may get tired eyes or headaches after a lot of visual work, even if their vision is clear. Reading is more difficult and school work can be affected. What causes hyperopia?

Extractions: 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. Symptoms The symptoms described above may not necessarily mean that you have hyperopia. However, if you experience one or more of these symptoms, contact your eye doctor for a complete exam.

It occurs when an eye is too short for the cornea 's curvature. Light rays entering the eye try to focus behind the retina , and as a result a blurred image is produced. Back Farsighted individuals, however, can use their focusing muscles to 'pull' the image forward onto the retina. In a young person with severe hyperopia, or once presbyopia sets in around age 45, distant objects are seen more clearly than near objects.
