Treatment

There are many ways of treating refractive errors. Most common ways of treatment are eyeglasses and contact lenses. There are other forms of treatment like laser eye surgery (lasik), orthokeratology and natural vision correction.

eyeglasses,contact lenses, and refractive surgery are the primary options to treat the visual symptoms of those with refractive disorders.Orthokeratology
is the practice of using special rigid contact lenses to flatten the cornea to reduce myopia.

Practitioners and advocates of alternative therapies often recommend eye exercises and relaxation techniques such as the Bates method. However, the efficacy of these practices is disputed by scientists and mainstream eye care practitioners and remains controversial. A 2005 review of scientific papers on the subject concluded that there was "no clear scientific evidence" that eye exercises were effective in treating myopia.

There is no universally accepted method of preventing myopia. Some clinicians and researchers recommend plus power (convex) lenses in the form of single vision reading lenses or bifocals. Although a recent Malaysian study suggested that undercorrection of myopia caused more rapid progression of myopia, the reliability of the data has been called into question.[61] Many myopia treatment studies suffer from any of a number of design drawbacks: small numbers, lack of adequate control group, failure to mask examiners from knowledge of treatments used, etc.

The standard treatment for myopia is to say that it is inherited and that minus lenses are the only answer. However, much research indicates that myopia is actually caused by prolonged reading and other close work. According to this viewpoint, minus lenses increase myopia and plus lenses can be used to prevent it.

Various methods have been employed in an attempt to decrease the progression of refractive disorders. Altering the use of eyeglasses between full-time, part-time, and not at all does not appear to alter much their progression. Bifocal and progressive lenses have not shown significant differences in altering the progression of refractive errors suck as myopia.
