The word 'hyperopia' is correct and usable in written English.
Hyperopia is a medical term that refers to a common vision condition, also known as farsightedness. It is characterized by difficulty focusing on nearby objects, while distant objects appear clear. Example: The optometrist diagnosed the patient with hyperopia and prescribed corrective lenses to improve their farsighted vision.
Depending on the situation, important nonsurgical treatments for strabismus may include correcting any underlying nearsightedness (myopia), farsightedness (hyperopia), or astigmatism with eyeglasses or fitting glasses with prisms.
In children, a common contributor to acquired strabismus is farsightedness (hyperopia), which, when severe enough, can secondarily cause the eyes to cross as the child tries to focus on an object (accommodative esotropia).
In contrast to the focussing of the normal (emmetropic) eye, in which the image of the visual field is focussed on the retina, the image may be focussed in front of the retina (nearsightedness, or myopia), or behind the retina (farsightedness or hyperopia).
Corrective lenses for hyperopia are designed to supply the additional convexity needed for focusing.
In some eyes, rays of light from distant objects are not brought to a focus on the retina but are focused on a plane in front of the retina, as in myopia (nearsightedness), or behind the retina, as in hyperopia (farsightedness).
Side effects of RK include progressive corneal flattening leading to farsightedness (hyperopia) and starburst patterns attributed to diffraction from the surgical scars encroaching on the eye's pupil.
Eyeglasses, also called glasses or spectacles, lenses set in frames for wearing in front of the eyes to aid vision or to correct such defects of vision as myopia, hyperopia, and astigmatism.
Hyperopic laser in situ keratomileusis (H-LASIK) and photorefractive keratectomy for hyperopia (H-PRK) are common surgical methods that reshape the cornea to improve vision in hyperopic patients.
LASIK, also called laser-assisted in situ keratomileusis, laser-based eye surgery commonly used to correct nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
In hyperopia, distant objects can sometimes be brought into focus by using the accommodative power of the lens, and in young people there is usually sufficient accommodation to enable them to see close up as well.
However, hyperopia is a factor in the development of some kinds of strabismus and vision loss (amblyopia) in children, and high degrees of myopia may be associated with serious degenerative changes within the eye, particularly the retina.
