I-lens kunye ne-cornea ngokuqhelekileyo zinomzimba ojikelezayo. Ukuphululwa kwesikhumba saso kubizwa ngokuba yi-astigmatism. Esi sifo sisona sizathu esona siphumo sokubona, ngokuqhelekileyo sidibaniswa ne-myopia kunye ne- hyperopia .
Ukuxilongwa kwe-pathology kuncedwa nguvavanyo lwe-astigmatism. Ukuziqhuba ngokulula, ngenxa yale nto ayikho imfuneko yokutyelela i-ophthalmologist.
Iimpawu zovavanyo lwe-astigmatism
Iimpawu zobuncwane bentambo ye-cornea okanye i-lens:
- ukuchithwa kokucaciswa kombono;
- intloko;
- ukuphazamiseka, ukuphazamiseka okanye ukuxubusha kwezinto;
- ukukhathala ngokukhawuleza xa kusebenza, kufuna i-eye strain;
- myopia;
- hypermetropia.
Kubalulekile ukuba uqaphele ukuba le mpawu ayisoloko ibonisa ukuba khona kwe-astigmatism. Ukuxilongwa kufuneka kuhlolwe ngenyameko.
Uvavanyo lweemvavanyo zokuxilongwa kwe-astigmatism
Umfanekiso ogqithiseleyo, ovumela ukuchonga i-pathology - inkwenkwezi ye-Siemens.
Inombolo yovavanyo 1:
- Hlela ukuze iphethini lisezantsi kwamehlo.
- Phakathi kwentloko kunye neskrini kufuneka kube ngumgama malunga no-35-50 cm.
- Ukuqwalasela ngokucophelela umfanekiso.
Ngeempazamo ezibonakalayo, imitha, engafikeleli phakathi, iyaqala ukuphazamisa, ukuhamba okanye ukudibanisa nemvelaphi. Kungabonakala ukuba umfanekiso uba yinto engafanelekanga - imirhozo emhlophe iphendulela abamnyama kunye nangoko. Kwakhona, abantu abane-astigmatism babona imida yokubonakala ngokucacileyo kwemizila ekwakhekeni kwe-ellipse okanye amanani amaninzi, kunokuba isangqa.
Inombolo yovavanyo 2:
- Musa ukutshintsha isikhundla esithathwe kwimeko yangaphambili.
- Vala iliso elinye ngesundu okanye iphepha, qwalasela umfanekiso.
- Phinda okufanayo kwelinye iliso.
Yonke imigca emfanekisweni ifana nombala kunye nobubanzi, kwaye amaqela kwicandelo ngalinye ahambelana ngokuthe ngqo. Ukuba kubonakala ukuba oku akunjalo, kunokubakho i-astigmatism.
Inombolo yovavanyo 3:
- Ukuhlala ukuze inkwenkwezi ibe kwinqanaba lentloko, kumgama wama-25-30 cm.
- Ngaphandle kokuvala enye nelinye iliso, jonga ngokucophelela kwimida.
Njengoko kuvavanyo lwangaphambili, yonke imigca kwienkwenkwezi ibalingana ngokumnyama kwaye ide. Phakathi kwendawo bajikela kwisangqa esifanelekileyo. Xa kubonakala ngathi ezinye iigqeba zikhanyisa okanye ziba mnyama, zininzi, zide, kwaye ziphakathi kwendawo yesikwerelo, i-ellipse, isibalo sesibhozo okanye esinye isibalo, kufuneka uqhagamshelane ne-ophthalmologist.
Ngaba ufuna iimvavanyo ze-Amsler ze-astigmatism?
Lo mzekelo ngamanye amaxesha kusetyenziswa ukuxilongwa kwe-astigmatism njengendlela yokufumanisa ukukhubazeka okongeziweyo okubonakalayo, ngokukodwa- ukuhlaselwa kwe-macular .
Ukuzaliseka:
- Xa ugqoka ii-lens okanye iiglasi zihlala zigqoka.
- Hlela umfanekiso kwisigaba sebhulophu yempumlo, kumgama wama-25-30 cm.
- Ukugubungela iliso elinye, ukujonga kwinqanaba eliphakathi, ukukhumbula indlela igridi ibonakala ngayo.
- Phinda elinye iliso.
Ngombono oqhelekileyo, imigca yegridi iya kuhlala isicaba, ingenabala, ukuphazamiseka okanye ukuphazamiseka. Ngaphandle koko, kufuneka u tyelele ingcali.
