Presbyopia

Presbyopia mamiriro mune iyo lens yeziso inorasikirwa nekwaniso yayo yekutarisa. Izvi zvinoita kuti zviome kuona zvinhu kumusoro.

Iyo lens yeziso inoda kuchinja chimiro kuti itarise pazvinhu zviri padyo. Iko kugona kwe lens kushandura chimiro kuri nekuda kwekusimba kweiyo lens. Iko kusimba kunodzikira zvishoma nezvishoma sevanhu vanokwegura. Mhedzisiro yacho inononoka kurasikirwa mukugona kweziso kutarisa pazvinhu zviri padyo.

Vanhu kazhinji vanotanga kucherechedza mamiriro pazera remakore makumi mana nemashanu, pavanoona kuti vanofanirwa kubata zvekuverenga kure kure kuti vatarise pazviri. Presbyopia chikamu chechisikigo cheichi chembere uye inobata munhu wese.

Zviratidzo zvinosanganisira:

• Kuderera kwekutarisa kugona kwezvinhu zviri padyo
• Eyestrain
• Kutemwa nemusoro

Mutapi wezvehutano anozoongorora bvunzo yeziso. Izvi zvinosanganisira zviyero zvekutora mushonga wemagirazi kana lenzi dzemagetsi.

Miedzo inogona kusanganisira:

• Kuongorora kwetina
• Tsvina yekuvimbika bvunzo
• Refraction bvunzo
• Yakatsemura-mwenje bvunzo
• Kuona zvakanaka

Iko hakuna mushonga we presbyopia. Pakutanga presbyopia, iwe unogona kuona kuti kubata zvekuverenga zviri kure kure kana kushandisa hombe kudhinda kana yakawanda mwenje yekuverenga kunogona kukwana. Sezvo presbyopia inowedzera, iwe uchada magirazi kana malensi ekuverenga kuti uverenge. Mune zvimwe zviitiko, kuwedzera bifocals kune iriko tsamba yekunyorera ndiyo mhinduro yakanakisa. Magirazi ekuverenga kana bifocal tsamba inoda kusimbiswa paunenge uchikura uye uchirasikirwa neakawanda kugona kutarisa padhuze.

Pakazosvika makore makumi matanhatu nemashanu, kuwanda kwemalensi kusununguka kunorasika kuitira kuti girazi rekuverenga magirazi risazoramba richisimba.

Vanhu vasingade magirazi ekuona kure vangangoda hafu yemagirazi kana kuverenga magirazi.

Vanhu vari kuona pedyo vanogona kukwanisa kubvisa magirazi avo ari kure kuti vaverenge.

Nekushandisa kwema-lenses, vamwe vanhu vanosarudza kugadzirisa rimwe ziso rekuona pedyo uye rimwe ziso rekuona kure. Izvi zvinonzi "monovision." Iyo nzira inobvisa kudiwa kwemabifocals kana kuverenga magirazi, asi inogona kukanganisa kudzika kwekuona.

Dzimwe nguva, monovision inogona kugadzirwa kuburikidza neye laser kuona kururamisa. Iko kune zvakare bifocal yekubatana lensi iyo inogona kugadzirisa kune ese ari padyo uye ari kure kuona mune ese maziso.

Maitiro matsva ekuvhiya ari kuongororwa ayo anogona zvakare kupa mhinduro kune vanhu vasingade kupfeka magirazi kana kutaurirana. Maitiro maviri anovimbisa anosanganisira kuisa lens kana pini membrane mune iyo cornea. Izvi kazhinji zvinogona kudzoserwa, kana zvichidikanwa.

Kune makirasi maviri matsva emadonhwe eziso mukusimudzira ayo anogona kuve anokwanisa kubatsira vanhu vane presbyopia.

• Imwe mhando inoita kuti mudzidzi ave mudiki, izvo zvinowedzera kudzika kwekutarisa, kwakafanana nepini yekamera. Kukanganisa kwemadonhwe aya ndechekuti zvinhu zvinoita sezvisinganetsi. Zvakare, iwo madonhwe anopera pamusoro pekupfuura kwezuva, uye iwe unogona kunge uine nguva yakaoma kuona paunobva pachiedza chakajeka kuenda kurima.
• Rumwe rudzi rwemadonhwe runoshanda nekupfava iyo lens yemusikirwo, inova isingachinjiki mu presbyopia. Izvi zvinobvumira lens kuti ichinje chimiro sezvayakaita pawakanga uri mudiki. Iyo yakareba-mhedzisiro mhedzisiro yemadonhwe aya haazivikanwe.

Vanhu vari kuvhiyiwa cataract vanogona kusarudza kuve nerudzi rwekuisa lens inovabvumidza kuti vaone zvakajeka kure uye kumusoro padyo.

Chiratidzo chinogona kururamiswa nemagirazi kana malensi ekutaurirana.

Kuona kuoma kunowedzera kuwedzera nekufamba kwenguva uye kusiri kugadziriswa kunogona kukonzera matambudziko nekutyaira, mararamiro, kana basa.

Fonera mupiki wako kana ophthalmologist kana uine ziso kushushikana kana uchinetseka kutarisa pazvinhu zvepedyo.

Iko hakuna kudzivirirwa kwekudzivirira kwepresbyopia.
