Presbyopia kweso

I-Presbyopia yeliso, eyaziwa ngokuba yi-senile myopia, yintlupheko yombono ehambelana nokuphulwa kweso iso ngenxa yokutshintsha kwexesha elidala. Kukholelwa ukuba uphuhliso lwe-presbyopia ludibaniswa neenguqu ezenzeka ngexesha lobudala kwi-lens (ukulahleka kwe-elasticity, ukunyanzeliswa kwamanzi, ukunyanzelisa) kwaye ngenxa yoko - ukuphulwa kwamandla akhe okutshintsha i-curvature.

Ngokungafani ne-hyperopia yokuzalwa komntwana okanye yokuqala, enokuchaphazela iliso elinye kuphela, i-presbyopia ivame ukubonwa kwimiba emibini kunye nokunciphisa okufanayo kumbono.

Iimpawu ze-presbyopia

I-pathology ibonakalisa ngokolu hlobo lulandelayo:

1. Kukho ukukhathala ekufundeni, ukusebenza kwikhompyutheni, imisebenzi efuna ukulayishwa okubonakalayo.
2. Ngomthwalo omude osondeleyo, kukho ukuziva kakubi kunye nentlungu emehlweni.
3. Kunzima ukuqwalasela iinkcukacha ezincinane kufuphi.
4. Ukufunda ngokukhululekile, kufuneka ukwandise umgama phakathi kwesicatshulwa kunye namehlo.

Unyango lwe-presbyopia yamehlo

Ubude obunxulumene nobudala, njengomthetho, bubumnene okanye buyingqinisiso, kodwa kunqabile kakhulu ukudlulela kwisigaba esibalulekileyo. Unyango oluphandwayo olunxulumene nokutshintshwa kwe-lens, mhlawumbi, nangona kungasetyenziswa rhoqo.

Ngokuqhelekileyo unyango lwe-presbyopia lusekelwe ekusetyenzisweni kwonyango oluxhasayo kunye nolungiso.

Ukulungisa umboniso nge-presbyopia usebenzisa iiglasi okanye iilensi. Kwaye, ukuba phambi kokuba iingxaki zomntu zingabonwa, kwaye xa ukhangeleka kumgama, ubuqhetseba obubonakalayo buhlala, ngoko ke inzuzo inikwe amaphulo asetyenziswa kuphela ukufunda, ukusebenza kwikhompyutha kunye neminye imisebenzi efuna ukuhlola izinto kufuphi. Ngenxa yokukhubazeka okubonakalayo, xa iiglasi zifuneka rhoqo, udibaniso lwamalensi luya kulungeleka isigulane.

Ingxaki eyinkimbinkimbi ngakumbi yi-presbyopia ubukho bokuba isigulane esibhekene nesigulane. Ngokuchasene neenkolelo ezithandwayo, kunye nobudala, ukunciphisa ukudibanisa akutshintshi, kwaye ukuphuhliswa kwamehlo okudala akusiququzeleli i- myopia . Ngako oko, abantu abanjalo kufuneka baqalise iimbini zombini zeglasi, ukufunda nokude, okanye ulungise i-myopia kunye neelensi zokufunda, ukubeka iiglasi eziphezulu. Enye inketho yokulungiswa kukusetyenziswa kwee-lens ezikhethekileyo ze-lens.

Unyango olusekelayo lubandakanya ukuthatha imithi yevithamini kunye nokusetyenziswa okuzodwa okumele kukuncedise ukuxhatshazwa kweso.
