Izibuko nge izimbobo - silindele umphumela?

izibuko Pinhole, noma izibuko nge izimbobo, ngokuvumelana abakhiqizi, kukhona nomqeqeshi umbono ukulungiswa. Angaba ulungise futhi myopia futhi hyperopia. Abakhiqizi futhi athembisa umbono obungcono astigmatism futhi asthenopia (iso ukukhathala, zezifo ezingelapheki).

Ukubona eduze (myopia) kwenzeka indoda lapho ukusonteka of yeso, lapho imisebe yokukhanya kungukuthi kuyi-retina, kodwa phambi kwayo. Isizathu salokhu mkhuba - lube buthaka imisipha iso, okuyinto ubambe apula. Hyperopia - kuba ngumkhuba lapho kwakhiwa isithombe nezikhonzi retina. Ngokuvamile, lonyaka eziphathelene ne-izinguquko. Astigmatism - kuyinto ukungakhuli okuyinkimbinkimbi ezikubonayo, esehlisa acuity ezibukwayo ku ibanga naseduze.

Izibuko zamehlo kanye izimbobo ekuqaleni emehlweni izibuko kodwa esikhundleni lens banayo ipuleti ne izimbobo ezincane. Abakhiqizi zithi lona esisha, esungulwe ngesisekelo imithetho physics optical (kwalungiswa izinkunga zokubona, defragmentation, ukuphazamiseka ecucuza elikhanyayo). Kubantu hhayi ababeyizazi physics futhi imithi, lezi zenzakalo abonakale eyinqaba futhi kungacaci. Kodwa lokumba imininingwane, akekho inikeza. Isimiso yokusebenza amaphuzu anjalo kusekelwe into defragmentation mkhuba ngenkathi okwandisa ukudepha kwenkundla, ngenxa esithombeni useyakwazi ncamashi kuyi-retina, futhi umbono ngcono. Kodwa, lo mkhuba is njengoba nomphumela beso ( "peeping emgodini") eyaziwa. Ngaphezu kwalokho, encishisiwe nomthelela imisipha iso, okuyinto enomthelela ukuphumula yabo.

Abakhiqizi athembisa ukuthi izibuko nge izimbobo emkhosini esiqondile imiyalelo bese uzisebenzisa ukwakha imizuzu okungenani 30 ngosuku bayakwazi ukubuya umbono eziyikhulu amaphesenti nje ngonyaka. Kutuswa ukuqala imizuzu 10. Ngokokuqala ngqá umuntu ahlangabezane ukungakhululeki, kodwa ukujwayela ngokuhamba kwesikhathi. Kulezi izibuko ungafunda, ukubukela i-TV, umsebenzi kwi-computer, enze omunye umsebenzi.

Kunenye umbono. Ochwepheshe abaningi bakholelwa ukuthi izibuko nge izimbobo - ithuluzi engenamsebenzi. Njengoba myopia cishe engelapheki ngokwako, okungukuthi, ngaphandle kokuphazanyiswa zangaphandle, Amazing akusho ayibulale, ungakwazi kuphela ukumisa ukulahlekelwa umbono. Hyperopia kulula ukuvimbela iso imodi kubona, futhi ukwenza ukuzivocavoca esikhethekile emehlweni. Astigmatism - ngokuvamile azalwa naso Isici buka, ungakwazi ukuqeda, kodwa ngaleso myopia efanayo namanje uhlala nge ukwelashwa okufanelekile kusuka kuye.

Kucwaningo olwenziwa eMelika, isheke amaphuzu nge izimbobo eyenziwe e-United States, luveza ukuthi le divayisi yalutho. Liyakushintsha umbono ayilungile. Ngaphezu kwalokho, njengoba kwaba njalo, lokhu akukona ukuthuthukiswa yesimanje. amadivaysi Okufanayo ibe khona Ephakathi. Kodwa kukhona amapuleti perforated ngokuhamba kwesikhathi indawo lens, okuyinto zibelula, futhi uzuze kukho ngaphezulu.

Ngakho, ngisho noma amaphuzu kulo mgodi futhi bheka engavamile kakhulu futhi ebonakala athembisa ngesimangaliso, kuwufanele ezindla kanjani lesi simangaliso enomqondo. Akuyona yonke into ivela isikhangiso njengoba ubuchwepheshe cutting edge, bona kuyinto.
