Abafundi bezikolo eziziiprayimari nabasesekondari baya kuqala iiholide zabo zehlobo ngeveki. Iingxaki zabantwana ziya kuphinda zijolise ekuqwalaseleni kwabazali.
Kwiminyaka yakutshanje, phakathi kweendlela ezininzi zothintelo lweMyopia kunye noLawulo, iiLenoticle iilensi, ezinokuthi zinciphise ukuphuculwa kwe-myopia, ziye zathandwa kakhulu phakathi kwabazali.
Ke, ungazikhetha njani iilensi zokuhombisa? Ngaba bafanelekile? Zithini amanqaku kwi-optometry? Emva kokufunda lo mxholo ulandelayo, ndicinga ukuba abazali baya kuba nokuqonda okungcono.
Zithini iilensi zokudelela?
Ngokubanzi, iilensi zokude zezokuhlewa ziilensi ze-Microstred I-Microstred Lenses, yenzelwe ukuba ibe nendawo ephambili yendawo kunye nendawo emazantsi, entsonkothileyo malunga neeparamitha ze-optical kunye nokufuna okungaphezulu kunamagama afanelekileyo kunemifanekiso eqhelekileyo.
Ngokukodwa, indawo ephakathi isetyenziselwa ukulungisa i-Mypia ukuqinisekisa "umbono ocacileyo", ngelixa i-peripheral iyilelwe ukuvelisa i-myfocus ngendlela eyodwa yoyilo. Iimpawu ze-Defocus Defocus eziveliswe kwezi ndawo zinokuthintela ukukhula kwe-axis yamehlo, ngaloo ndlela kunciphisa ukuqhubela phambili kweMyopia.
Nguwuphi umahluko phakathi kweelensi eziqhelekileyo kunye neelensi ze-Dereya?
I-lense eqhelekileyo ye-monofocacal igxile kumfanekiso ophakathi wombono kwi-retina kwaye inokulungisa umbono kuphela, ukuvumela umntu ukuba abone ngokucacileyo xa enxiba;
I-lensess ye-deFouch engagxilanga kuphela umfanekiso wembono ephambili kwi-retina ukuba ivumele ukuba sibone ngokucacileyo kodwa sijonge i-tefocus ye-tefocus ecothisa i-myopia.
Ngubani onokusebenzisa iilensi zokuhombisa?
I-1. I-Myopia ayigqithanga kwi-1000 degrees, i-aligmatism engagqithi kuma-400 degrees.
2. Bantwana kunye nolutsha olunokuqina kakhulu kwaye abafuna ngokukhawuleza iimfuno zeMypia.
3. Abo bangalungelanga ukunxiba iilensi ze-Ortho-K okanye abafuni ukunxiba iilensi ze-Ortho-K.
Qaphela: Izigulana ezinesithukuthezi, umbono we-binormal obi we-binouscular, kunye ne-anisoometropia kufuneka zivavanywe ngugqirha kwaye ziqwalasele ngokufanelekileyo.
Kutheni ukhethadeFouchIilensi?
1. Iilensi zokude zisebenze ekulawuleni i-myopia.
2. Inkqubo yokulungisa iilensi zokuhlola ii-Dereding ilula kwaye akukho mahluko omkhulu kwinkqubo yoviwo evela kwelensi eqhelekileyo.
I-3. Iilensi zokudelela azinxibelelane ne-cornea yeliso, ke akukho ngxaki yosulelo.
4. Xa kuthelekiswa neelensi ze-Ortho-K, iilensi zokuhombisa kulula ukuyigcina kwaye inxibe, iilensi ze-Ortho-K kufuneka zihlanjwe kwaye zibulawe ngalo lonke ixesha zithatyathwa kwaye zifuna ukhathalelo olukhethekileyo lokukhathalela.
I-5. Iilensi zokude zibiza ixabiso eliphantsi kune-ortho-k lenses.
I-6.
