2 planning prudently for the future; "large goals that required farsighted policies"; "took a long view of the geopolitical issues" [syn: farseeing, foresighted, foresightful, long, longsighted]
- Being unable to focus with one's eyes on near objects.

Hyperopia, also known as hypermetropia or colloquially as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short or when the lens cannot become round enough), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves toward the eye, the eye must increase its power to keep the image in focus on the retina. If the power of the cornea and lens is insufficient, as in hyperopia, the image will appear blurred.
People with hyperopia can experience blurred vision, asthenopia, accommodative dysfunction, binocular dysfunction, amblyopia, and strabismus.
Hyperopia is often confused with presbyopia , another condition that frequently causes blurry near vision. Presbyopes who report good far vision typically experience blurry near vision because of a reduced accommodative amplitude brought about by natural aging changes with the crystalline lens.
Classification of hyperopiaHyperopia is typically classified according to clinical appearance, its severity, or how it relates to the eye's accommodative status.
Classification by clinical appearance
- Simple hyperopia
- Pathological hyperopia
- Functional hyperopia
DiagnosisVisual acuity is affected according to the amount of hyperopia, as well as the patient's age, visual demands, and accommodative ability.
TreatmentVarious eye care professionals, including ophthalmologists, optometrists, orthoptists, and opticians, are involved in the treatment and management of hyperopia. At the conclusion of an eye examination, an eye doctor may provide the patient with an eyeglass prescription for corrective lenses.
Minor amounts of hyperopia are sometimes left uncorrected, however, larger amounts may be corrected with convex lenses in eyeglasses or contact lenses. Convex lenses have a positive dioptric value, which causes the light to focus closer than its normal range.
Hyperopia is sometimes correctable with various refractive surgery procedures.
