MYOPIA (NEARSIGHTEDNESS): Nearsightedness, medically known as myopia, refers to vision that is good at close range but not at a distance. It generally occurs because the eyeball is too long or when the cornea has too much curvature. This increased distance between the cornea and retina, causes light to converge in front of the retina, rather than on it. Nearsightedness is diagnosed during routine eye exams and possible treatments include eyeglasses, contact lenses, LASIK (laser-assisted in situ keratomileusis), PRK (photorefractive keratectomy), and acrylic corneal implants. Because myopia is associated with an increased risk of serious sight-threatening conditions, such as myopic macular degeneration, retinal detachments, cataracts, and glaucoma, it is important to implement MYOPIA CONTROL methods at an early age, thereby reducing the risk in the future.
HYPEROPIA (FARSIGHTEDNESS): Farsightedness, medically known as hyperopia, refers to vision that is good at a distance but not at close range. Farsightedness occurs when the eyeball is shorter than normal or when the cornea has too little curvature. This reduced distance between the cornea and retina, causes light to converge behind the retina, rather than on it. If you are mildly farsighted, your eye care provider may not recommend corrective treatment at all. However, if you are moderately or severely hyperopic, you may have several treatment options available, including eyeglasses, contacts lenses, LASIK (laser-assisted in situ keratomileusis), and PRK (photorefractive keratectomy).
