Miedzo yekuona kumba

Miedzo yekuona kumba inoyera kugona kuona yakajeka ruzivo.

Pane matatu ekuedzwa bvunzo anogona kuitwa pamba: Amsler grid, kure kure kuona, uye padyo nekuyedzwa kuyedzwa.

AMSLER GRID TEST

Bvunzo iyi inobatsira kuona macular degeneration. Ichi chirwere chinokonzeresa kuona, kukanganisa, kana mabara asina chinhu. Kana iwe uchiwanzopfeka magirazi ekuverenga, zvipfeke bvunzo iyi. Kana iwe ukapfeka bifocals, tarisa kuburikidza neyepazasi kuverenga chikamu.

Ita bvunzo neziso rega rega zvakasiyana, kutanga kurudyi uye kuruboshwe. Bata grid rekuyedza pamberi pako, 14 inches (35 masentimita) kure neziso rako. Tarisa pane dot iri pakati peiyo grid, kwete pane iyo grid pateni.

Paunenge uchitarisa pane dot, iwe uchaona iyo yakasara yeiyo gridi mune yako yekumusoro maonero. Mitsetse yese, yakatwasuka uye yakatwasuka, inofanirwa kuoneka yakatwasuka uye isina kutsemuka. Ivo vanofanirwa kusangana panzvimbo dzese dzekuyambuka pasina nzvimbo dzinoshaikwa. Kana paine chero mitsara inoita kunge yakamonyaniswa kana kuputswa, cherekedza nzvimbo yavo pane iyo grid uchishandisa peni kana penzura

KUONA KWEMAHARA

Iyi ndiyo yakajairwa chati yeziso vanachiremba vanoshandisa, iyo yakagadziridzwa kuti ishandiswe pamba.

Iyo chati yakasungirirwa kumadziro pamwero weziso. Mira 10 tsoka (3 metres) kure nechati. Kana iwe ukapfeka magirazi kana malensi ekuona kure kure, zvipfeke izvo bvunzo.

Tarisa ziso rega rega, kutanga kurudyi uye kuruboshwe. Chengeta maziso maviri akavhurika uye vhara ziso rimwe nechanza choruoko.

Verenga iyo chati, uchitanga nemutsetse wepamusoro uye uchifamba uchidzika nemitsetse kusvika zvanyanya kuti uverenge mavara. Nyora nhamba yetambo diki-diki yaunoziva iwe kuti unoverenga nemazvo. Dzokorora nerimwe ziso.

PEDYO CHIONO

Izvi zvakafanana nemuedzo wekuona daro pamusoro, asi unongobatwa chete 14 inches (35 masentimita) kure. Kana iwe ukapfeka magirazi ekuverenga, zvipfeke kuitira bvunzo.

Bata iri pedyo rekuona bvunzo kadhi anenge gumi nemana masendimita (35 masentimita) kubva pameso ako. Usaunze kadhi chero padhuze. Verenga iyo chati uchishandisa ziso rega rega zvakasiyana sezvatsanangurwa pamusoro. Nyora saizi yetambo diki iwe yawakakwanisa kuverenga nemazvo.

Unoda nzvimbo yakavhenekerwa inokwana gumi tsoka (3 metres) pakureba kwekuona bvunzo, uye zvinotevera:

• Kuyera tepi kana chiyero cheyadhi
• Machati eziso
• Tepi kana teki kuti urembedze machati eziso pamadziro
• Penzura yekurekodha zvabuda
• Mumwe munhu wekubatsira (kana zvichibvira), sezvo vachigona kumira padhuze nechati uye vokuudza kana ukaverenga mavara nemazvo

Iyo chati yechiratidzo inoda kuiswa kumadziro pazinga reziso. Maka pasi nechidimbu chetepi makiromita gumi (matatu metres) kubva pachati iri kumadziro.

Iyo bvunzo dzinokonzera kusagadzikana.

Chiono chako chinogona kuchinja zvishoma nezvishoma iwe usingazvizive.

Miedzo yekuona kumba inogona kubatsira kuona matambudziko eziso uye ekuona pakutanga. Miedzo yekuona kumba inofanirwa kuitwa uchitungamirwa nemubatsiri wako wezvehutano kuti aone shanduko dzinogona kuitika pakati pekuongororwa kwemaziso. Ivo havatore nzvimbo yehunyanzvi kuongorora maziso.

Vanhu vari panjodzi yekukura kwe macular degeneration vanogona kuudzwa na ophthalmologist wavo kuti aite iyo Amsler grid bvunzo kazhinji. Zviri nani kuita bvunzo iyi kwete kazhinji kanopfuura kamwe chete pasvondo. Macular degeneration shanduko inoitika zvishoma nezvishoma, uye iwe unogona kuipotsa kana iwe ukaedza zuva nezuva.

Zvakajairwa mhedzisiro yeimwe neimwe bvunzo zvinotevera.

• Amsler grid bvunzo: Yese mitsara inoonekwa yakatwasuka uye isina kuvhunika isina nzvimbo dzakatsauswa kana dzakashaikwa.
• Kureba kwekuona bvunzo: Mavara ese ari pamutsetse 20/20 anoverengwa nemazvo.
• Pedyo nekuona bvunzo: Iwe unokwanisa kuverenga mutsara wakanyorwa 20/20 kana J-1.

Mhedzisiro isina kujairika inogona kureva kuti une dambudziko rekuona kana chirwere cheziso uye iwe unofanirwa kuve nehunyanzvi kuongorora kweziso.

• Amsler grid bvunzo: Kana iyo grid ichiita seyakavhiringika kana kuputswa, panogona kunge paine dambudziko neiyo retina.
• Kureba kuona bvunzo: Kana iwe usinga verenge iyo 20/20 mutsetse nenzira kwayo, inogona kunge iri chiratidzo chekuona padyo (myopia), kuona zviri kure (hyperopia), astigmatism, kana kumwe kusarongeka kweziso.
• Pedyo nekuona bvunzo: Kusakwanisa kuverenga iyo diki mhando chingave chiratidzo chekuchembera kuona (presbyopia).

Iyo bvunzo haina njodzi.

Kana uine chimwe chezviratidzo zvinotevera, tora ongororo yeziso yehunyanzvi:

• Dambudziko rekutarisa pazvinhu zviri padyo
• Kuona kaviri
• Kurwadziwa kweziso
• Kunzwa kunge kune "ganda" kana "firimu" pamusoro peziso kana maziso
• Chiedza chinopenya, nzvimbo dzine rima, kana mifananidzo yakaita semweya
• Zvinhu kana zviso zvinotaridzika kusviba kana kusviba
• Mhete dzeRainbow-dzakatenderedza dzakakomberedza magetsi
• Mitsara yakatwasuka inotarisa wavy
• Kunetseka kuona husiku, kunetseka kugadzirisa kumakamuri ane rima

Kana vana vaine chero chinotevera chiratidzo, vanofanirwa zvakare kuve nehunyanzvi kuongorora kweziso:

• Maziso akayambuka
• Zvakaoma kuchikoro
• Kunyanyisa kubwaira
• Kuswedera padyo nechinhu (semuenzaniso, terevhizheni) kuti uzvione
• Musoro uchirerekera
• Kuchema
• Meso emvura
