Alternative Names: Hyperopia Causes, incidence, and risk factors: 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.

Eye Care Basics Glossary Amblyopia A condition resulting in the functional non-use of one eye due to a problem of focusing an image on the retina; also known as "lazy eye." Astigmatism A condition that occurs when the cornea is misshapen to some degree, causing light to focus improperly on the retina. Cataracts A condition caused by a clouding of the internal lens of the eye, causing blurred or distorted vision. Color Vision Deficiency A genetically inherited trait in which the ability to distinguish some colors is less than normal. Cornea The transparent, rounded tissue covering the front of the eye and serving as the first focusing mechanism of light entering the eye. Diabetic Retinopathy Associated with diabetes, an eye disease that can lead to blindness. Farsightedness See Hyperopia Floaters Small, cloudy specks of various sizes that form in the vitreous fluid of the eye.

107. Patient Education Library - Hyperopia Farsightedness or hyperopia occurs when the eye is too small or the cornea is too flat. A person with hyperopia is able to see objects at a distance, http://www.cascadeye.com/patienteducation/eyeeducation/hyperopia/hyperopia.htm

Hyperopia (Farsightedness) The cornea and the lens work together to focus images from the visual world on the back of the eye (the retina). If an image is out of focus, it is typically because the overall shape of the eye is incorrect or the cornea does not have the proper curvature. Farsightedness or hyperopia occurs when the eye is too small or the cornea is too flat. When this happens, visual images are focused behind the retina. A person with hyperopia is able to see objects at a distance, but has trouble with objects up close, like books or newspapers. Many people are not diagnosed with hyperopia without a complete eye exam. School screenings typically do not discover this condition because they test only for distance vision. Treatment includes contact lenses or glasses which correct for near vision. Corrective lenses should be worn for near tasks, such as reading, but do not need to be used for distance vision tasks, such as driving.

Many simple cells show half-wave rectification to contrast reversing patterns. (See also Full-Wave Rectification Haploscopic Stimulation Different stimuli for the two eyes.

Our Doctors Laser Vision Correction Cataract Surgery Conductive Keratoplasty ... Retinal Conditions (Including Macular Degeneration) Surgery Cornea Glaucoma General Eye Care Latest Information ... Financing Seminars SEARCH Home Common Refractive Problems Refraction refers to the bending of light rays as they pass through one medium to another, such as from air to water. As the light rays pass through the tissues of the cornea and the lens, they are bent (refracted) in a manner that brings them into focus upon the retina. Three components determine an eye's refractive characteristics: the shape of the cornea, the power of the lens, and the length of the eyeball. When these components are in correct proportion to one another, light is focused directly on the retina resulting in clear vision (normal). However, in many eyes, these components are not in the correct proportion to one another, resulting in the refractive problems of myopia (nearsightedness) hyperopia (farsightedness) , and astigmatism. Another common problem, presbyopia , begins to affect persons over 40 years of age. Presbyopia, or "aging vision," occurs as the natural lens of the eye becomes less pliable, which make focusing on near objects increasing difficult.
