Myopia, also known as near-sightedness and short-sightedness, [ 5] is an eye disease [ 6][ 7][ 8] where light from distant objects focuses in front of, instead of on, the retina. [ 1][ 2][ 7] As a result, distant objects appear blurry while close objects appear normal. [ 1]
Scleral reinforcement surgery. Schematic diagram of the human eye. ( Sclera labeled on left.) Specialty. ophthalmology. [ edit on Wikidata] Scleral reinforcement is a surgical procedure used to reduce or stop further macular damage caused by high myopia, which can be degenerative.
Pseudomyopia. Pseudomyopia (from ψεῦδο, "pseudo": false; and μυωπία "myopia": near sight) occurs when a spasm of the ciliary muscle prevents the eye from focusing in the distance, sometimes intermittently; this is different from myopia which is caused by the eye's shape or other basic anatomy. Pseudomyopia may be either organic ...
Treatment. Eyeglasses, contact lenses, refractive surgeries, IOL implantation [ 2] Frequency. ~7.5% (US) [ 5] Far-sightedness, also known as long-sightedness, hypermetropia, and hyperopia, is a condition of the eye where distant objects are seen clearly but near objects appear blurred.
Orthokeratology lens. Orthokeratology, also referred to as Night lenses, Ortho-K, OK, Overnight Vision Correction, Corneal Refractive Therapy (CRT), Accelerated Orthokeretology, Cornea Corrective Contacts, Eccentricity Zero Molding, and Gentle Vision Shaping System (GVSS), is the use of gas-permeable contact lenses that temporarily reshape the cornea to reduce refractive errors such as myopia ...
7-Methylxanthine ( 7-MX ), also known as heteroxanthine, is an active metabolite of caffeine (1,3,7-trimethylxanthine) and theobromine (3,7-dimethylxanthine). [ 1][ 2] It is a non-selective antagonist of the adenosine receptors. [ 1][ 2] The compound may slow the progression of myopia (nearsightedness). [ 1][ 2] It is under investigation for ...
When refractive errors in children are not treated, the child may be at risk of developing ambylopia, where vision may remain permanently blurry. [19] Because young children typically do not complain of blurry vision, the American Academy of Pediatrics recommends that children have yearly vision screening starting at three years old so that unknown refractive errors or other ophthalmic ...
Aberrations of the eye. The eye, like any other optical system, suffers from a number of specific optical aberrations. The optical quality of the eye is limited by optical aberrations, diffraction and scatter. [1] Correction of spherocylindrical refractive errors has been possible for nearly two centuries following Airy's development of methods ...
