Pamashoko ose evanhu, zviratidzo zvichida zvinonyanya kukosha.
Kutarisa kuonekwa kwechitema
Kuti uone maonero anooneka, maophthalmologists anoshandisa matafura chaiwo. Kuti uone maziso evanhu vakuru, kazhinji kashandisa tafura yeSivtsev, iyo mitsetse yakarongwa netsamba, pasi, duku (tafura ine chiLatini inozivikanwa inonzi Snellen tafura). Zvisinei, tafura yakadaro haisi nguva dzose yakubvumira kunyatsoongorora kubwinya kwezvinhu zvakasikwa, nokuti munhu anogona kufungidzira tsamba nechimiro. Rimwe rakarurama, kunyange risingawanzoshandiswa, ndiro gorovin tafura, ine mitsetse yezvindori, ne discontinuities nenzira dzakasiyana. Kuti uone kushanda kwakanaka, vana vanoshandisa tafura nemifananidzo yezvinhu uye mhuka.
Mabheji akadaro kazhinji ane mitsetse 12, ane tsamba kana zviratidzo zvehukuru hwakasiyana, uye akachengeterwa mu decimal decimal. Mutsara wega wega unofananidzwa nekuwedzera kwemaonero anooneka ne 0.1. Chimiro chekuona zvakagadziriswa chinofanirwa kuti chinopindirana nechiguniti, umo munhu wacho anonyatsosiyanisa mutsara wegumi kubva kure nemamita mashanu. Dzimwe nguva kune vanhu vane maziso anooneka makuru kupfuura 1, vanogona kusiyanisa mitsetse iri pasi pegumi.
Panguva ino, kuwedzera pamatafura, nzira dzekugadzirisa kuongorora maziso anoonekawo anoshandiswawo, achishandiswa zvinokonzerwa ne refractometers nezvimwe zvigadzirwa. Nzira dzakadaro dzinofunga kuti dzakarurama uye zvinangwa.
Iko cheko rinowanikwa zvakasiyana paziso rimwe nerimwe, kupfigira rechipiri, sezvo maziso anooneka angave akasiyana pane ziso rimwe nerimwe.
Zviitiko zvinokanganisa kuona
Maziso evanhu anonyanya kutarisana nekunze kwezvinhu: saka pakujekesa kwemazuva ose tinoona zviri nani kudarika murima, zviratidzo zvakajeka zvinowanzova nani kupfuura pembera, zvakare maronda maziso anobatsira zviri nani muchiedza, uye yakasvibiswa nemamiriro ehutano maziso uye urongwa hwemakoni nematanda. Asi zvinhu izvi zvakasikwa, uye kazhinji hazvibatsiri kuongororwa kwezvinhu zvakaratidzwa zviripo pane imwe.
Asi kuderedza kuonekwa kwehutano ndiyo dambudziko rinowanzoitika rinogona kukonzerwa nekuchinja kwehutano, pamwe chete nezvizvarwa, zvakanyanya kuoma kwemaziso, pamwe nekurwara kana kushungurudzika.
Kudzorerwa kwemaonero anooneka
Zvichipa kukosha uye kukosha kwehutsika dzakadaro, nzira dzakawanda dziri kushandiswa zvino dzingave dzichidzorera kuonekwa kwakanaka.
- Kudzidzira maziso. Tichifunga nezvemaitiro ayo maziso anoonekwa zuva rega rega, gymnastics yakadaro ichabatsira kunyange kune vanhu vasina zvirwere zvekuona zvisinei, kunyanya sezvo zviri nyore. Vhura maziso ako, uye unyatsodziputira neminwe yako, mumitambo yechirungu. Kubwinya 10-12 dzimwe nguva, uchifambisa zvakanyanya. Vhura maziso ako uye tora kutarisa kwemasere kana masheta. Kazhinji kasimudza meso ako kumusoro, odzikisa pasi, tamisa meso ako kurudyi - kuruboshwe. Gymnastics inogarwa kwemaminitsi 10-15 kangana pazuva.
- Magirazi ekuvandudza maitiro anooneka. Magirazi akasiyana-siyana, anogadziriswa nemakomba maduku, anoshandiswa kugadzirisa kuneta kwemaziso uye kuvandudza maitiro ekuona apo lensi yacho inenge yakazara.
- Kugadzirira. Pakutanga, kugadzirira kwakadaro kunosanganisira mavitamini akawanda anokwana, LHC additives nedzimwe mishonga inoshandiswa pakugadzirisa zvirongwa zvemagetsi mu retina nekuvandudza kushanda kwayo. Simbisa kuonekwa kwechirwere chemishonga iyi hakubatsiri,
asi kukwanisa kudzivirira kuwedzera kuora uye kugadzirisa mamiriro acho ezvinhu. Uyewo, kune mishonga yemishonga (yakashandiswa zvakakwana maererano nemirairo yeophthalmologist) inotarisirwa kuremara masumbu eziso uye nokudaro kuvandudza ropa kune ziso.
Muzviitiko zvakawanda, kana kuonekwa kwakanyanya kunogadziriswa, nzira chete inobatsira inoshandiswa, uye nzira dzakasara (gymnastics yemaziso, madonhwe, nezvimwewo) inokwanisa kupa zvishoma zvishoma. Zvisinei, iyo ndiyo nzira inokosha inodzivirira nekudzivirira kuwedzera kuora kwemaonero.
