Astigmatism: A refractive error where objects at all distances have a distorted appearance ("streaked" or stretched, with elongated shapes and unequally blurred borders). Symptoms of astigmatism include squinting, eye strain, headaches and reading problems. Read more about astigmatism.
Cataract: Clouding of the natural lens of the eye, usually caused by aging in conjunction with other risk factors, such as exposure to the sun's UV rays, smoking, steroid intake and diabetes. Symptoms include blurred vision, glare, halos around lights, colors that are less bright, a cloudy spot in your vision and, sometimes, temporary vision improvement. Read more about cataracts.
Corneal refractive therapy (CRT): The use of specially designed gas permeable contact lenses to reshape the cornea during sleep and temporarily correct myopia (with or without mild-to-moderate astigmatism). Developed by Paragon Vision Sciences. Similar to orthokeratology.
Glaucoma: Disease characterized by elevated intraocular pressure, which causes optic nerve damage and subsequent peripheral vision loss. Most people have no initial symptoms of chronic (open-angle) glaucoma, but you can develop peripheral vision loss, headaches, blurred vision, difficulty adapting to darkness and halos around lights. Other forms of glaucoma (e.g., closed-angle glaucoma) may have additional symptoms such as eye pain, a pupil that doesn't respond to light, redness, nausea and a bulging eye. Learn more about glaucoma.
Hyperopia: A refractive error where a person must exert a greater-than-normal focusing effort to see distant and near objects clearly. Depending on the farsighted person's age and degree of hyperopia, objects may be clear or blurred without glasses. Other symptoms of hyperopia include headaches, eye strain, and avoidance of reading and other near tasks. Also called farsightedness. Learn more about hyperopia.
Macular Degeneration Disorder: characterized by changes in the eye's macula that result in the gradual loss of central vision. The exact cause is unknown, but appears to be related to a genetic predisposition, smoking and several other risk factors. Central vision may be blurred, distorted (metamorphopsia) or shadowy before vision loss occurs. Please click here to learn more about age-related macular degeneration.
Myopia: A refractive error where a person can see near objects clearly but distant vision is blurred. Myopia typically begins in childhood and progresses during the school years. The primary symptom of nearsightedness is squinting. Also called nearsightedness. Learn more about myopia.
Presbyopia: Condition in which the aging eye beginning at around age 40 is unable to focus at all distances, often noticed when print begins to blur. Additional symptoms include eye strain, headaches, and squinting. Read our article about presbyopia.
