Ziso iri optical system apo chiedza chemazuva chinotarisa pane retina, kuumba mifananidzo. Izvo zvinowanzoonekwa mumeso evanhu zvinenge 23.5 mm, asi pane dzimwe nguva pane kuputsa kwehukuru hukuru uye, sechikonzero, matambudziko nehuono. Chirwere chakadai chakawanda kwazvo myopia, kana seanonzi - myopia.
Chii chinonzi medium degree myopia?
Muchirapa, myopia yakakamurwa kuita zvitatu zvechidimbu: isina simba, iri pakati uye ine simba.
Ne-medium-degree myopia, maonero anooneka zvakasiyana kubva kune -3 kusvika -6 diopters.
Kana myopia yezinga risina simba haigoni kukonzera kusanzwisisika kwakanyanya uye mukutanga kwekutanga kusatomboda kuvhara magirasi kana lenzi, ipapo ne medium degree myopia corrective devices (magirazi kana lenzi) zvinotenderwa. Mukuwedzera, nokuda kwechimwe chikamu chemyopia, maviri maviri egirazi anowanzotarisirwa: imwe yakakwana yekururamisa, kure, uye imwe yepa 1.5-3 diopter zvishoma kudarika nekushanda pamwe nezvinhu zvakanyatsowanikwa. Uyezve, kutanga nedhigiriji yepamusoro, zviputi zvinowanzoshandiswa: ndiko kuti, magirazi ane lenzi yakabatana, pane imwe hafu yepamusoro kune lenzi yakasimba, pakuona zvinhu zviri kure, uye pasi - zvakanyanya kusimba, pakuverenga.
Myopia wepakati pezinga neastigmatism
Astigmatism chimwe chimiro chekuona, chinokonzerwa nekuti iyo cornea ine chimiro chisina kumira. Nokudaro, simba rayo rokudzoka rinogona kusiyana, uye mairi haatauri mune imwe nzvimbo, asi mune zvakati. Somugumisiro, zvinhu zvinoshandiswa uye zvinorasikirwa zvakajeka. Astigmatism inogona kuratidzika, asi kazhinji inowanikwa pamwe chete ne myopia. Uyezve, pamberi peMyopia, astigmatism inogona kutanga isati yaonekwa. Asi kana iwe usingakwanisi kugadzirisa myopia nemagetsi anowanika, ipapo astigmatism inogona kuitika. Muchiitiko ichi, kuti udzore zvakajairika maziso ekuona, majekiseni anokosha anodiwa, kururamisa kwete kungoona zvishoma, asiwo chirema ichi.
Mushonga we medium medium degree myopia
Kugadzirisa kuswedera pedyo nehutano nenzira dzokurapa hazvibviri. Munhu anogona kudzorera kuonekwa kwakanaka kuburikidza nemubatsiro wezvigadziriswe zvakananga: magirasi kana lenzi, asi kwete. Kana zvisina kudaro, kurapwa kwemishonga, physiotherapy, gymnastics yemaziso hazvirevi kurwara, asi pakuchengetedza maonero nekudzivirira kufambira mberi kwemyopia.
Kana pane myopia isiri yekufambira mberi yechipfuva chepakati chemaziso maviri, zvino chiratidzo chinogona kugadziriswa chirwere. Basa rinowanzogadziriswa kugadzirisa dhigirii yemero myopia inonzi laser vision correction. Nekubatsirwa kwea laser, chimiro chekodenia chinoshanduka, chinoita kuti ive imwe yeri lens uye inobatsira kuisa pfungwa yakarurama.
Apo chiratidzo chinowedzera nevanopfuura 1 diopter gore negore, zvinonzi nezvemyopia inopfuurira yepakati peji. Myopia yakadaro ine nguva, kana isingaregi kukura kwayo, inoenda kune imwe yero yakaoma. Kana nzira dzakachengetedza dzichimisa kukura kwechirwere hachikwanisi, ipapo shandisa kuongororwa nokukurumidza, asi chinangwa chayo ndechekuita kuti kuderedza kuora
Kukanganisa mumwero unoenzanisira kuenzanisa myopia
Nechirwere chemyopia, mitambo inofanirwa kurapwa zvakanyanyisa kupfuura neyero ruduku. Izvo zvinodiwa kudzivisa mitoro yakawandisa, naizvozvo mhedziso pamusoro pekugamuchirwa kwemamwe mitambo inofanira kutorwa ne oculist.
Vechidiki vanobatanidzwa muuto, vane medium degree myopia, vanosarudzwa muboka B uye vanoonekwa sevasingashandisi.
