Vadzidzi vepuraimari nesekondari vachatanga zororo ravo rechirimo muvhiki.Zvinetso zvevana zvokuona zvichavazve chinhu chikuru chengwariro yavabereki.
Mumakore achangopfuura, pakati penzira dzakawanda dzekudzivirira nekudzora myopia, defocusing lenses, iyo inogona kuderedza kukura kwe myopia, yave ichinyanya kufarirwa pakati pevabereki.
Saka, ungasarudza sei defocusing lenzi?Dzakakodzera here?Ndeapi mapoinzi ekucherechedza muOptometry?Mushure mekuverenga zvinyorwa zvinotevera, ndinofunga kuti vabereki vachave nekunzwisisa kuri nani.
Chii chinonzi defocusing lens?
Kazhinji, defocusing lenzi ndeye microstructured spectacle lenses, akagadzirirwa kuva nepakati optical nzvimbo uye microstructured nzvimbo, iyo yakanyanya kuoma maererano ne optical parameters uye inodiwa zvakanyanya maererano nekukodzera pane yakajairika magirazi.
Kunyanya, nzvimbo yepakati inoshandiswa kugadzirisa myopia kuti ive nechokwadi che "chiono chakajeka", nepo dunhu rekutenderera rakagadzirirwa kuburitsa myopic defocus kuburikidza neakakosha optical dhizaini.Iyo myopic defocus masaini anogadzirwa munzvimbo idzi anogona kutadzisa kukura kweiyo axis yeziso, nekudaro kunonoka kufambira mberi kwemyopia.
Ndeupi musiyano uripo pakati peakajairwa lenzi uye defocusing lenzi?
Ordinary monofocal lenses inotarisa pakati pechiratidzo chifananidzo pane retina uye inogona chete kugadzirisa maonero, zvichiita kuti munhu aone zvakajeka kana akaapfeka;
Defocusing lenzi haingotarise mufananidzo wepakati wechiratidzo paretina kuti utibvumire kuona zvakajeka asi zvakare kutarisa periphery pane kana pamberi pe retina, ichigadzira peripheral myopic defocus iyo inononoka kuvandudzwa kwemyopia.
Ndiani anogona kushandisa defocusing lenzi?
1. Myopia isingapfuuri madhigirii 1000, astigmatism isingadariki 400 madhigirii.
2. Vana nevechiri kuyaruka vane maonero ari kuwedzera nekukurumidza uye vane zvinodiwa nekukurumidza zvekudzivirira nekudzora myopia.
3. Avo vasina kukodzera kupfeka Ortho-K lenses kana vasingadi kupfeka Ortho-K lenses.
Cherechedza: Varwere vane strabismus, abnormal binocular vision, uye anisometropia vanofanira kuongororwa nachiremba uye kuona zvakakodzera sezvakakodzera.
Sei kusarudzadefocusinglenzi?
1. Defocusing lenses inoshanda mukudzora myopia.
2. Nzira yekukodzera defocusing lenses iri nyore uye hapana misiyano yakakura mukuongororwa kwekuongorora kubva kune yeakajairika lenzi.
3. Defocusing lenses haibatanidzi necornea yeziso, saka hapana dambudziko rehutachiona.
4. Kuenzaniswa neOrtho-K lenses, iyo defocusing lenses iri nyore kuchengetedza uye kupfeka, Ortho-K lenzi dzinoda kugezwa uye kuuraya utachiona pese painobviswa nekuiswa uye inodawo mhinduro dzakakosha dzekuvachengeta.
5. Defocusing lenzi akachipa kupfuura Ortho-K lenzi.
6. Kuenzaniswa neOrtho-K lenzi, defocusing lenses inoshanda kune vanhu vakawanda.
