Ukuzivocavoca okulula okungu-4 okuthuthukisa ukubona okungaboni kahle

-Delile

• Ukwenza kanjani izivivinyo
• 1. Bheka phezulu
• 2. Bheka phansi
• 3. Bheka ngakwesokudla
• 4. Bheka ngakwesobunxele

Kunokuzivocavoca umzimba okungasetshenziselwa ukuthuthukisa ukungaboni kahle nofifi, ngoba welula imisipha exhunywe ku-cornea, okusiza ekwelapheni i-astigmatism.

I-Astigmatism ibonakala ngokufogoloza kwe-cornea, engadalwa yizici zofuzo futhi ingacwayizi isikhathi eside, nokuyinto ejwayelekile kubantu abasebenza ngamakhompyutha noma abachitha isikhathi esiningi komakhalekhukhwini noma kumathebulethi. Kujwayelekile ukuthi uma kwenzeka i-astigmatism umuntu ephathwa yikhanda kaningi futhi azizwe ekhathele futhi adinga ukugqoka izibuko noma amalensi okuxhumana ukuze abone futhi.

Enye imbangela evamile yokungaboni kahle yi-presbyopia, eyaziwa kakhulu ngokuthi ukubona okukhathele. Bona izivivinyo ezisiza ukunciphisa ubuhlungu beso nokukhathala.

Ukwenza kanjani izivivinyo

Indawo yokuqala kufanele ihlale ikhanda libheke phambili, ngaphandle kwezingilazi noma ilensi yokuxhumana. Umhlane kufanele ume mpo futhi ukuphefumula kufanele kube nokuthula. Ngemuva kwalokho kufanele:

1. Bheka phezulu

Okunye kokuzivocavoca okusiza ukugxila embonweni ukubheka phezulu, ngaphandle kokuhambisa ikhanda lakho, ngaphandle kokukikiza noma ukucindezela amehlo, futhi ugcine amehlo akho kule ndawo cishe imizuzwana engama-20, ucwayiza amehlo akho ngasikhathi sinye, okungenani u-5 izikhathi.

2. Bheka phansi

Ukuzivocavoca okwedlule kufanele futhi kwenziwe ubheke phansi, ngaphandle kokuhambisa ikhanda, ngaphandle kokukikiza noma ukucindezela amehlo akho, futhi ugcine amehlo akho kule ndawo cishe imizuzwana engama-20, ucwayiza amehlo akho ngasikhathi sinye, okungenani amahlandla ama-5.

3. Bheka ngakwesokudla

Ungenza futhi lo msebenzi ngokubheka ohlangothini olungakwesokudla, futhi ngaphandle kokuhambisa ikhanda, nokugcina amehlo akho kule ndawo imizuzwana engama-20, ukhumbula ukucwayiza njalo ngemizuzwana emi-3 noma emi-4.

4. Bheka ngakwesobunxele

Ekugcineni, kufanele wenze umsebenzi owedlule, kepha kulokhu ubheke kwesobunxele.

Ukwenza lula ukusebenza kokuzivocavoca, ungakhetha into bese uyibuka njalo.

Lezi zivivinyo kufanele zenziwe nsuku zonke, okungenani ama-2 ngosuku, ukuze imiphumela ibonwe futhi cishe emavikini ama-4 kuye kwayi-6 kufanele kube sekuvele kungenzeka ukuthi kuthuthukiswe umbono othile.

Ngaphezu kwalokho, ukuqinisekisa impilo yamehlo, kubalulekile ukuthi ungahlikihli noma uhlunge amehlo akho ukuze uzame ukubona kangcono. Kubalulekile futhi ukugqoka kuphela izibuko zelanga ezisezingeni, ezinokuhlunga kwe-UVA ne-UVB, ukuhlunga imisebe ye-ultraviolet, ephazamisa nokubona.

Kunconywa nokuthi uphuze okungenani amalitha ayi-1.5 amanzi ngosuku ukugcina umzimba, futhi ngenxa yalokho i-cornea inamanzi amaningi.
