Qodobbada tayada gudaha ee lenses resin:
1. Tayada agabka aasaasiga ah
Tayada substrate-ka ayaa go'aamisa adkeysiga muraayadda iyo kalsoonida daboolka.Substrate wanaagsan oo cad oo dhalaalaya, waqti dheer la isticmaalo oo aan sahlanayn in jaalaha ah;Oo muraayadaha qaarkood waxay isticmaalaan wakhti aan dheerayn jaalaha, xitaa dahaarka off.Muraayadaha wanaagsan ee aan xoqin, xoqin, timo, godad, muraayadda indho-indheynta iftiinka, dhamaystirka sare.Ma jiraan dhibco, dhagaxyo, dildilaacyo, goobooyin iyo dildilaac gudaha muraayadda, iftiinkuna waa dhalaalaya.
2. Heerka muraayadda
Muraayadaha wax soo saarka badan leh ayaa loo qaybiyaa darajooyin kala duwan taas oo ay ugu wacan tahay kala duwanaanshiyaha tayada gudaha, qiimaha alaabooyinka sare iyo kuwa hooseba aad ayay u kala duwan yihiin.
3. Tusmada dib-u-celinta
Markasta oo uu sareeyo tusaha wax-soo-celinta, muraayadda khafiifka ah, iyo qiimaha sareeyo.
4. Dahaarka iyo daawaynta ka hortagga ultraviolet
xaashida xabagta waa la engejin karaa (iska caabin xoq), lidka-milicsiga, anti-static, boodhka, ka baaraandegidda daahan biyuhu sida ugu badan oo darsin lakab, processing daahan kala duwan ayaa door ka duwan, haddii la yareeyo habka processing daahan, tayada muraayada aad loo dhimi doono.Sidoo kale, aad bay waxyeello ugu leedahay indhaha haddii muraayadaha aan ka hortagin fallaadhaha ultraviolet loo xidho sida lenses ka hortagaya fallaadhaha ultraviolet.Isha bini'aadamka waxay nuugtaa iftiinka ultraviolet aad u badan si ay si fudud ugu keento cuduro kala duwan oo indhaha ah sida keratitis photoinduced, cataract iyo macular degeneration.
5. Nooca muraayadda
Kala duwanaanshaha calaamaduhu waxay horseedaan kala duwanaansho xagga tayada iyo qiimaha.Tayada muraayadaha ayaa si toos ah uga muuqda astaanta muraayadda.Tayada muraayadda caanka ah waa mid wanaagsan oo xasilloon.Sida muraayadda gadaal looga farsameeyo, haddii ay run tahay iyo haddii kaleba, macaamiishu ma la socon karaan oo ma aqoonsan karaan, inta badan waxay ku tiirsan yihiin daacadnimada hawlwadeenka.Habka iimaanka wanaagsan ayaa ah in marka macaamiishu isku dhejiyaan muraayadaha, mulkiilaha dukaanku waa inuu muujiyaa calaamadda, kala duwanaanta, index refractive iyo xaaladda dahaarka ee lenska ee dukumeentiga, iyo awoodda looga hortagayo iftiinka ultraviolet waa in sidoo kale loo sharaxaa macaamilka.Haddii muraayadda resinka guud ahaan lagu qoro, farqigu aad buu u weyn yahay, tayada gudaha ee muraayadda lama garanayo.Darajada ABC waxa kaliya oo loo istcimaalaa in lagu kala saaro marka ay soo saaruhu soo saarayaan, dhab ahaantii, heerka qaran uma baahna kala soocis noocaas ah.Dabcan, iyada oo aan loo eegin fasalka ABC ee muraayada u qalma.
6. Hufnaanta iyo lebbiska indhaha ee muraayadda
Muraayada ka qabo meel 30 cm ka fog isha oo ku fiiri muuqaalka fog ee muraayadda.Haddii muuqaalku uu cad yahay oo aan qalloocin, oo aysan jirin boodi goob marka muraayadda si tartiib ah loo dhaqaajinayo, daah-furnaanta iyo lebbiska indhaha ee muraayadda ayaa wanaagsan.
7. Jihada axial ee lenska astigmatism
Warqad madhan si aad u sawirto fargeeto iskutallaabta toosan, geli lens-ka caaro-wareejin garaafyada ka sarreeya 30 sentimitir, muraayadaha la arki karo waxay dhaqaajiyaan iskutallaabta fargeetada, muraayadda gudaha iyo marka lagu xiro garaafyada istaroogga istaroogga, garaafyada ayaa si togan u gudubtay, halkaasoo dhidibka lenska tiirka iyo xariiq toosan, ka dibna muraayadaha ayaa si isdaba joog ah u socday xariiq toosan;U fiirso xariiqa ka duwan xariiqda ka baxsan muraayadda marka aad dhaqaaqeyso, iyo xariiqdani waa jihada dhidibka iftiinka.Dhaqaaji muraayadda si gudaha iyo dibaddaba ay saf ugu galaan, halkan waa dhidibka kala duwanaanshiyaha.Ka dib markaad ku calaamadiso muraayadda, cabbir xagasha axial iyo horizontal ee xarunta lens-ka oo leh protractor, kaas oo ah darajada axial.
8. Barokaca xarunta indhaha
Ku sawir iskutallaab weyn warqad cad oo khafiif ah, cad, oo toosan ah.Ku qabo muraayadda isha iyo iskutallaabta dhexdooda, ku fiirso qaabka iskutallaabtu ka muraayadda hal il, haddii gudaha iyo dibadda muraayadda aysan ahayn mid saf ah, waxaad dhaqaajin kartaa muraayadda, si gudaha muraayadda bannaanka muraayadda xariiqda.Isticmaal buraash ama qalin isha si aad u dhigtid barta yar ee bartamaha muraayada, taas oo ah xarunta indhaha.Ka dib markaad tilmaanto xarumaha indhaha ee labada lenses, u fiirso oo is barbar dhig in xarumaha indhaha ee laba geesoodka ah ay siman yihiin, oo ku cabbir masaafada u dhaxaysa labada xarumood taliye yar si aad u aragto in masaafada u dhaxaysa labada xarumood ay la mid tahay masaafada loo qoray ardayga .Haddii iskutallaabta muraayadda la leexiyo, waxay muujinaysaa inuu jiro walaac gudaha ah ama cufnaanta indhaha ee muraayadda oo aan sinnayn.
9. Xidho raaxada
Xiro bilaa dareen, dawakhaad iyo indho barar, walxaha fiirsashada maaha kuwo bluish ah, ma qalloocan.Markaad wax iibsanayso, gacanta ku hay muraayadaha oo ku eeg walxaha fog hal il oo muraayada ah.Kor iyo hoos u rux muraayaddaDhalanteedka dhaqdhaqaaqa walxaha fog waa inuusan dhicin.
10. Ilaalinta
Muraayadaha tayada sare leh ayaa 100% xannibi kara UV A iyo UV B, iyagoo siinaya ilaalinta ugu waxtarka badan ee qofka xiran.
