Hyperopia

Farsightedness or hyperopia, occurs when light penetrating the eye focuses behind the retina, instead of straight on it. This is because of an eye that is relatively too short, or the refractive powers of the cornea and lens of the eye are comparatively too weak. Young adults and children with mild to moderate cases of farsightedness often see close objects clearly as the lens is able to acclimate or change its shape. People having hyperopia can see distant objects clearly but have difficulty seeing objects that are near. With intact vision this point of convergence, where the light rays are focused, is on the retina. This transpires 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 light entering the eye focuses behind the retina, instead of squarely on it hence close objects look blurred. As you age, your eyes lose the competency to change the shape of the lens to focus on near objects (accommodation ). Farsightedness is often first observed after age 40 when the eyes begin to lose their ability to accommodate. As you age, your eyes lose the ability to shift the shape of the lens to focus on near objects ( accommodation ). Farsightedness is a risk factor for closed-angle glaucoma. Thence, patients with hyperopia should discuss glaucoma testing with their eye care practitioner. Yet, at later years the eye gradually loses the ability to accommodate and blurred vision becomes more apparent.

Farsightedness is faction seeing objects which are nearby. Long sightedness or hyperopia, seems if a persons eyeball is too short or when the cornea is too flat when compared to the normal eye. A inclusive optometric examination will include testing for farsightedness. If you are farsighted, you see reticent 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. Awating on the degree of farsightedness and the age of the individual, some farsighted people may see clearly at both distance and near through the process of accommodation, or focusing of the lens in the eye. In other cases, your optometrist can prescribe eyeglasses or contact lenses to optically correct farsightedness by castrating the way the light enters your eyes.

Causes of Hyperopia

The common causes of Hyperopia :

• Long-sightedness is often adduce from birth, when the eyeball is short or the lens is too weak compared to the normal eye.
• Family history also partakes to long sightedness.
• Farsightedness is the consequence 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 frail
• Hyperopia results when the eyeball is too short or the cornea is too flat and the lens is unable to adjust its shape to see close objects clearly (the process called accommodation).

Symptoms of Hyperopia

Some common Symptoms of Hyperopia :

• Difficulty seeing up close
• Eye fatigue when reading
• Eye strain (headaches, pulling sensation, burning)
• Crossed eyes in children
• Achy feeling in eyes
• Blurred vision of close objects
• Headache while reading
• Aching eyes
• Glaucoma testing
• Eye movements
• central scotoma

Treatment of Hyperopia

• Cycloplegic refraction is most useful.
• The Fiengold formula (proprietary) may be used for a precrystalline lens implant.
• This procedure is most useful when the iris is light colored; it may not work when the iris is brown or dark.
• Hyperopia is commonly treated using corrective lenses, such as eyeglasses or contact lenses .
• Refractive surgery may be able to correct some forms of hyperopia.
• A homeopathic practitioner should be consulted for a proper recommendation.
• Eye drops of eyebright ( Euphrasia officinalis ) tea can relieve eye-strain and, taken orally with rosemary ( Rosemarinus officinalis ) in white wine, can improve vision. Schisandra ( Schisandra chinensis ) improves visual clarity.
• Farsightedness is easily corrected with glasses or contact lenses
• Surgical techniques are available for correcting farsightedness and can be used for those who do not wish to wear glasses or contacts.
