——Kana malenzi akanaka, sei achiachinja?
——Zvinosvota kuwana magirazi matsva uye kutora nguva refu kuajaira.
——Ndichiri kuona zvakajeka nemagirazi aya, kuti ndirambe ndichiashandisa.
Asi kutaura idi, zvokwadi ingakushamisa: Magirazi ane “upenyu hwapasherufu” zvomenemene!
Kana tichitaura nezve kutenderera kwekushandiswa kwemagirazi, unogona kutanga wafunga nezvemazuva ese anoraswa kana epamwedzi ekuona lenzi. Wanga uchiziva here kuti magirazi ekunyoreswa anewo mashoma ekushandisa kutenderera? Nhasi, ngatikurukurei kuti sei zvakakosha kugara uchichinja magirazi ako, kunyanya magirazi.
01 Lens Kupfeka uye Kubvarura
Sechikamu chepakati chemagirazi, lenzi ane chaiyo "optical properties," yakakosha pakuchengetedza hutano hwakanaka hwekuona. Zvisinei, zvinhu izvi hazvina kumira; zvinopesvedzerwa nezvinhu zvakasiyana-siyana zvakadai senguva, zvinhu, uye kupfeka.
Nokufamba kwenguva, sezvaunoshandisa optical lenses, ivo vanounganidza kusakara nekuda kweguruva mumhepo, netsaona mapundu, uye zvimwe zvikonzero. Kupfeka lenzi dzakakuvadzwa zvinogona kutungamira kune kuneta kwekuona, kuoma, uye zvimwe zviratidzo, uye zvinogona zvakare kuwedzera kusaona pedyo.
Nekuda kwekupfeka kusingadzivisike uye kuchembera, kugara uchichinja lenzi kwakakosha pakuchengeta magirazi ari muchimiro chakanaka chemaziso. Izvi hazvifanirwe kurerutswa!
02 Shanduko muKururamisa Chiono
Kunyangwe kana uchipfeka magirazi, hutsika husina kunaka hwakadai sekurebesa pedyo nebasa rekuona uye kushandisa zvakanyanya zvigadzirwa zvemagetsi zvinogona kudzika zvikanganiso zve refractive zviri nyore uye zvinotungamira mukuwedzera kwesimba rekunyorera. Uyezve, pwere dzinowanzova padanho repamusoro rokukura kwomuviri, kutarisana nedzvinyiriro huru yedzidzo, uye kazhinji kazhinji kushandisa midziyo yemagetsi, zvichiita kuti zvive nyore kuchinja muchiono.
Iko kururamisa kwekuona kunopihwa nemalenzi kunofanirwa kuvandudzwa nekukurumidza kuti ienderane nemamiriro ekuona azvino. Kune vechidiki vane myopia, zvinokurudzirwa kuve nekutarisa kwekutarisa mwedzi mitatu kusvika mitanhatu yega yega, nepo vakuru vachifanira kuwana imwe yega kusvika makore maviri. Kana iwe ukaona kuti magirazi ako haachakodzera kuchinja kwako refractive, unofanira kuatsiva nenguva.
Njodzi dzekuchengeta magirazi kupfuura Prime yavo
Kuti tidzivirire hutano hwemaziso edu, zvakakosha kutsiva magirazi sezvinodiwa. Kupfeka vaviri vakafanana nekusingaperi kunogona kuva nemigumisiro yakaipa pameso. Kana magirazi "akanonoka kugamuchirwa," anogona kukonzera zvinotevera:
01 Chirevo Chisina Kugadziriswa Chinotungamira Kukurumidza Kuora
Kazhinji, iyo refractive mamiriro emeso anoshanduka nekufamba kwenguva uye nenzvimbo dzakasiyana dzekuona. Chero shanduko yeparameter inogona kuita kuti magirazi aimbokodzera ave asina kufanira. Kana ma lens asina kuchinjwa kwenguva yakareba, izvi zvinogona kutungamirira kune kusawirirana pakati pechiyero chekugadzirisa maonero uye zvidikanwi chaizvo, kukurumidza kufambira mberi kwekukanganisa kwe refractive.
02 Kupfeka Kwakanyanya PaLenzi Kukuvadza Meso
Malenzi anogona kuchembera nekushandiswa kwenguva refu, zvichiita kuti kuderedzwa kujeka uye kutapurirana kwechiedza. Uyezve, mavanga uye madhigirii akasiyana-siyana ekupfeka anogona kukanganisa kutapurirana kwechiedza, zvichikonzera kusajeka kwekuona, kuneta kwemaziso, uye mumatambudziko akaomarara, zvinogona kuwedzera kutarisisa.
03 Magirazi Akaremara Anokanganisa Chiono
Unowanzoona shamwari dzakapfeka magirazi akaremara zvikuru—akakotamiswa pakurohwa paanenge achitamba mitambo kana kuti akapwanywa—kungoagadzirisa zvawo uye kuramba uchiapfeka. Zvisinei, nzvimbo ye optical ye lenzi inofanira kuenderana nechepakati pevadzidzi; kana zvisina kudaro, zvinogona kutungamira zviri nyore kumamiriro akaita selatent strabismus uye zviratidzo zvakaita sekuneta kwekuona.
Nokudaro, vanhu vakawanda vanofunga kuti chiono chavo chakadzikama—kuti chero bedzi magirazi akasimba, anogona kupfekwa kwemakore. Kutenda uku kwakarasika. Pasinei nerudzi rwemagirazi aunopfeka, kuongorora nguva dzose kwakakosha. Kana kusagadzikana kukamuka, kugadzirisa nenguva kana kutsiva kunofanira kuitwa. Kuchengeta magirazi ari muchimiro chakanaka kwakakosha kuchengetedza hutano hwemaziso edu.
