I-hypetropia yaziwa ngokuba yimbonakalo, kwaye iPresbypia ziingxaki zombono ezimbini ezibonakala ngathi, nangona zombini zibangela umbono ovuthuzayo, nangona zombini zibangela umbono ovuthuzayo, wahluka kakhulu kwizizathu zabo, iimpawu, kunye neendlela zokulungisa.
I-hyperopia (i-farks)
Isizathu: I-Hyperopia yenzeka ikakhulu ngenxa yobude obugqithisileyo beliso (iliso le-eyebot) okanye i-wasold ye-eyeBALD) okanye eyenza buthathaka amandla eliso, ebangela ukuba enze imifanekiso emva kwe-retina kunokuba ibethe ngqo kuyo.
Ukuhanjiswa kobudala: Inokwenzeka i-hypetropia nangaliphi na iminyaka, kubandakanya abantwana, abakwishumi elivisayo kunye nabantu abadala.
Iimpawu: Zombini izinto ezikufutshane nezikude zinokubonakala zibuthathaka, kwaye zinokuhamba kunye nokudinwa kwamehlo, intloko, okanye i-esotropia.
Indlela yokuGcobela: Ukulungiswa kudla ngokubandakanya ukunxiba iilensi ze-convex ukwenza ukukhanya kugxilwe ngokuchanekileyo kwi-retina.
I-Presbyopia
Isizathu: I-Persgoopia yenzeka ngenxa yokwaluphala, apho iilensi zeliso ziphulukana nobuchule bayo, kubangela ukuba iliso lokwakhiwa kweliso lijolise ngokucacileyo kwizinto ezikufutshane.
Ukuhanjiswa kweminyaka yobudala: I-Pressopia yenzeka kwindawo ephakathi nabadala, kwaye phantse wonke umntu uyayifumana njengoko bekhula.
Iimpawu: Olona phawu luphambili lububugqwirha kwizinto ezikufutshane, ngelixa umbono omde uhlala ucace gca, kwaye unokuhamba kunye nokudinwa kwamehlo, ukudumba kwamehlo, okanye ukukrazula.
Indlela yokufunda: Ukunxiba iiglasi zokufunda (okanye iiglasi zokwenza amandla) okanye iiglasi ezininzi eziqhubekayo, njengeeglasi ezininzi eziqhubela phambili, ukunceda ugxininiso lweliso kungcono kwizinto ezikufutshane.
Ngamafutshane, ukuqonda lo mahluko kusinceda ukuba sizibone ngcono ezi ngxaki zimbini zombono kwaye zithathe amanyathelo afanelekileyo okuthintela kunye nokulungiswa.
IXESHA LOKUQALA: I-DEC-05 ukuya ku-024
