Kweli nqaku, ikakhulu sithetha malunga nendlela esivavanya ngayo umgangatho weiilensi zeglasi.Kithina, umgangatho we-lens uxhomekeke kwimbonakalo kunye nomsebenzi.
Sonke siyazi ukuba i-lens yenye yezona ndawo zibalulekileyo kwiperiiiglasi, umgangatho we-lens uhambelana ngokuthe ngqo nomgangatho weeglasi.Sichitha imali eninzi, kwaye ngokuqinisekileyo sinethemba lokuthenga iperiiiglasi ezilungileyo.Ngokuqinisekileyo kulula ukukhetha iperiiiglasioyithandayo ngokwembonakalo, kodwa umsebenzi weelensi nawo ubaluleke kakhulu.Makhe sijonge indlela umzi-mveliso oyihlola ngayoumgangathoyeelensi.Ewe kunjalo, ukuba ungumthengi oqhelekileyo, ndiyathemba ukuba iya kuba luncedo kuwe.
1. Ukuhlolwa kwembonakalo.Ngombala, umbala ohlukeneyo, i-pitting, imikrwelo kunye nezinye iingxaki zomhlaba.Beka isiqwenga sephepha elimhlophe elingangcolisi ngaphantsi kwayo, kwaye ukhangele ngenyameko ukuba kukho naziphi na iingxaki ezingentla phantsi kokukhanya kwe-QC (ukukhanya okunamandla kunye nokufana okufanayo kunokukhanya kwemini eqhelekileyo).
2. Ukujonga inkcazo.Ngenxa yokuba i-lens ijikelezwe ngokubanzi, kufuneka sisebenzise i-oyile dipstick caliper ukulinganisa ubukhulu kunye nobukhulu belensi.
3. Uvavanyo lwe-Anti-friction.Sebenzisa iphepha elithile elirhabaxa okanye ilaphu okanye ezinye izinto ukuze uhlikihle umphezulu welensi emva naphambili kangangenani elithile lamaxesha ngamandla athile, uze ubone umphumo.Umgangatho ophezuluiilensi zinefuthe elingcono lokuchasa ukukhuhlana.
4. Ukuhlolwa kweCamber: Jonga i-camber ye-lens nge-camber meter.Indawo yokuhlola ixabiso le-curvature yeziko le-lens kunye ubuncinane namanqaku angama-4 ajikelezayo.Kuhlolo olulandelayo lwebhetshi, yibeke emcaba kwipleyiti yeglasi ukujonga ukuba idibene ngokulinganayo nepleyiti yeglasi.
5.Uvavanyo lokumelana nempembelelo.Ekwabizwa ngokuba luvavanyo lwebhola lokuwisa, sebenzisa i-dropball tester ukuvavanya ukuchasana kwempembelelo yelensi.
6. Uvavanyo lomsebenzi weLens.Okokuqala, kuxhomekeke kwimisebenzi ethile ye-lens, kwaye emva koko iqhuba uvavanyo oluhambelanayo.Ezona ziqhelekileyo ziyi-oyile-proof, i-waterproof, iqiniswe, njl., UV400, i-polarized, njl.
• A. Uvavanyo lokusebenza kobungqina be-oyile: Sebenzisa ipeni esekwe kwi-oyile ukuzoba kumphezulu welensi.Ukuba inokuqokelela ngokukhawuleza, yisule nge-lens ngokulula, ebonisa ukuba inomsebenzi wokukhusela ioli.Qwalasela iqondo lamanzi aneoyile eqokelelana kunye, kwaye wosule.Idigri ecocekileyo, hlola isiphumo sayo esichasene ne-oyile.
• B. Uvavanyo lokusebenza olungangeni manzi: faka i-lens emanzini acocekileyo kwaye uyikhuphe, yixube kancinci, amanzi aphezu komhlaba aya kuwa, ebonisa ukuba i-lens inomsebenzi ongenamanzi.Jonga umphumo wokungangeni manzi ngokweqondo lokuhla.
• C. Ukomelezwa kovavanyo lomsebenzi: Ngaphantsi kokukhanya kwe-QC, jonga ukuba kukho iglue ecacileyo phezu komhlaba kunye ne-periphery ye-lens, kwaye uyicinezele ngobumnene nge-blade.Inamandla alungileyo nokomelela.
• D. Uvavanyo lomsebenzi wePolarization: uvavanyo ngepolarizer.Okanye vula ifayile yeWORD yekhompyuter, kwaye emva koko ubambe ilensi ejonge kuyo kwaye uyijikelezise ngaxeshanye, umbala welensi uya kutshintsha ukusuka ekukhanyeni kuye kumnyama kwaye emva koko ube mnyama ngokupheleleyo, kwaye uqhubeke ujikeleza ukusuka kumnyama ukuya ekukhanyeni kancinci kancinci.Yipolarizer.Nika ingqalelo ukujonga ukufana kombala, njl., nokuba kumnyama ngokwaneleyo ukugweba umgangatho womsebenzi we-polarizing xa u-opaque.
• I-E. UV400 ithetha i-100% yokhuseleko kwi-UV.Iindondo zelangakwimarike ayinakuba nazo zonke iimpembelelo zokwahlula imitha ye-ultraviolet.Ukuba ufuna ukwazi ukuba iilensi ziyakwazi ukwahlula imitha ye-ultraviolet: fumana isibane semali ye-ultraviolet.kunye nephepha lebhanki.Ukuba ukhanyisa ngokuthe ngqoit, unokubona i-ultraviolet anti-counterfeiting yeimali yebhanki.Ukuba nge-lens kunye nomsebenzi we-UV400, i-anti-counterfeiting ayinakubonwa.
Ezi zingentla zezinye iindlela zokuhlola kunye nokuvavanya iilensi.Kakade ke, akukho mgangatho upheleleyo wayo.Wonke umthengi kunye nebhrendi nganye ineemfuno ezahlukeneyo zeelensi.Abanye bahlawula ingqalelo ngakumbi kwinkangeleko kwaye abanye bahlawula ingqwalasela ngakumbi kumsebenzi, ngoko ke ugxininiso lokuhlola luya kwahluka.
