Children under 7 years old, there are three. OOD about hypertrophy, is a normal physiological hypertrophy, with age, the eye axis is also accompanied by the development of the whole body gradually grow; hypertrophy was gradually reduced, and even developed to face, generally do not corrected. Hypertrophy is relatively high and there is Arabic?s, myopically should be corrected as soon as possible and often wearing glasses. Optometry examination must be in full paralysis of the culinary muscle with atropine, so adjust the disappearance of conditions. Internal Arabic?s should be done fully corrected, adhere to regular wear, must not be interrupted, leaving the collection to relax relaxed regulation. Children who can not recognize the vision chart, you can check the results of objective refraction minus 1. Make such a correction, the glasses are difficult to be accepted by children, wearing glasses should be preceded by atropine culinary muscle paralysis, wearing a medication every other day before the best times also maintain one week. So that it does not happen the culinary muscle spasm, and gradually adapt. After wearing glasses every 1 to 3 weeks later a second, visual acuity improved in order to observe its extent and degree of Arabic?s change the situation. If Arabic?s disappeared Arabic?s should be able to control and maintain a good binocular vision function in the case, lower diaper.
There were isotropic and decreased vision; although not high hypertrophy can just add mirrors to improve vision, but also can improve eyesight should definitely be given degree of hypertrophy correction. In short, the principle should be visual acuity improved to give the lowest degree of corrective lenses, to try to use regulation, thereby strengthening the collection of the eye, reducing mild to moderate hypertrophy. Bilateral myopically without Arabic?s, as fully corrected visual acuity difference of only 1 to 2 lines, can be implemented without cover; beyond three lines, all lines should be covered, or not fully covered.
Children should wear Cheap Ray Ban Sunglasses 1 year optometry examination. If diaper reduces, replace the lens, so as not to be due to excessive hypertrophy artificial myopia. We have many years of children Arabic?s optometry inspection found that generally children isotropic patients, after wearing corrective lenses a year, and then atropine culinary muscle paralysis optometry, refraction has not decreased, but increased somewhat 0.25D ? 0.50D, indicating that children hypertrophy due regulating force rich, not wearing corrective glasses ago, in order to obtain better vision over regulation, resulting in culinary muscle spasm, although continuous with atropine seven days, the regulation of culinary muscle force completely disappeared, through the rational use of corrective spectacles adjust quite a long time, in order to force the culinary muscle tension relaxed. School-age children and adolescents are subject to significant visual fatigue symptoms, such as chronic conjunctiva hypermedia, eye pain, headache, eye itching, eyelid spasms, Robyn, tired of learning or decreased vision, even if hypertrophy in 3.00D or less, also should be given to correction, normal vision, could wear while reading.
If normal distance vision, reading or doing other close work with symptoms should be given correction; usually not wearing glasses only for reading, doing close work wear; as far as there are symptoms, you need to always wearing glasses; principle to achieve the best vision of the highest diaper to give. Recessive hypertrophy part without correction, neurasthenia, poor health, regulation is weak or around the age of 35 who is reading the discretion to recessive hypertrophy correction is also 1/4 to 1/2.
Hypertrophy higher, except for children and adolescents due to tolerance and adaptability, can be used as a one-time correction, the other patient (not wearing low degree Cheap Ray Bans sunglasses who), due to the beginning of a corrective spectacles, right things like the magnification, the image distortion caused by spherical aberration and chromatic dispersion caused discomfort is unacceptable and should give the points, the initial height of its lens can stand corrected, let it adapt and then deepened.
