Ngethuba lenkqubo yokupholisa ukuveliswa kwe-lens, izinto ezifana nokungafani kwe-lens ubukhulu kunye nobudlelwane babo kunye nezixhobo zokupholisa zangaphakathi, umzekelo, ukupholisa ngokukhawuleza kwezinye iindawo kunye nokupholisa okucothayo kwezinye, kunokukhokelela kwisizukulwana soxinzelelo lwangaphakathi.
Ukupheliswa koxinzelelo lweLens
1. UPhuculo loBuchule boMveliso
Ukuze kuncitshiswe isizukulwana soxinzelelo lwangaphakathi ngexesha lokwenziwa kweelensi, abavelisi beelensi baqhubeka bekhulisa nokuphucula iindlela zokuvelisa. Ngexesha lenkqubo yokuvelisa iilensi, ilensi ifumana amanyathelo amathathu okunyanga ubushushu obuphezulu. Inkqubo yokuqala yokunyanga iguqula ilensi ukusuka kwimeko yolwelo ukuya kwimo eqinileyo kwaye isusa uxinzelelo lwendalo ngaphakathi kokuqinileyo. Iipilisi ezimbini ezilandelayo zijolise ekupheliseni uxinzelelo lwangaphakathi ngamaxesha amaninzi, ngaloo ndlela kufezekiswa isakhiwo sangaphakathi esifanayo se-lens.
2. Ukuphumla koxinzelelo lweLens
Ngokwengcaciso yomthetho kaHooke kwifiziksi, phantsi kweemeko zoxinzelelo oluqhubekayo, uxinzelelo luyehla ngokuthe ngcembe ngokuhamba kwexesha, into eyaziwa ngokuba yi-stress curve. Oku kuthetha ukuba i-orientation kunye nemiphumo yoxinzelelo lwe-shrinkage eyenziwa ngexesha lenkqubo yokuvelisa i-lens iyancipha ngokuthe ngcembe njengoko ixesha lokugcina lens emva kokunyuka kokunyuka. Ixesha lokuphumla loxinzelelo lwe-lens lihambelana ngokusondeleyo noxinzelelo kunye noxinzelelo lwangaphandle. Phantsi kweemeko eziqhelekileyo, uxinzelelo kwilensi luya kuncipha ukuya kubuncinci emva kweenyanga ezintathu emva kokugqitywa kwemveliso yelensi. Ngoko ke, ngokubanzi, uxinzelelo lwangaphakathi kwilensi lupheliswe ngokuyimfuneko emva kokuba lushiye umzi-mveliso.
Isizukulwana soxinzelelo kwiindondo zamehlo
Ukunika ingqiqo yoxinzelelo lwelensi, siyazi ukuba impembelelo yoxinzelelo kwimveliso yelensi yomntu incinci ngokwentelekiso, kwaye inokuthathwa njengengabalulekanga. Ke ngoko, kumgangatho wesizwe weelensi eTshayina, iiparamitha zoxinzelelo azifakwanga kwiikhrayitheriya zokufaneleka. Ngoko, uyintoni unobangela woxinezeleko lweglasi yamehlo? Oku kuhambelana kakhulu neteknoloji yenkqubo yokulungiswa kweglasi yamehlo.
Kwiivenkile ezithengisa i-eyeglass, ngexesha lenkqubo yokufakela i-lens yomhlaba kwisakhelo, i-optician igaya i-lens ibe nkulu kancinane kunobukhulu obufunekayo ukukhusela i-lens ukuba ikhululeke kakhulu kwaye ikhutshwe ngokulula kwisakhelo. Oku kuqinisekisa ukhuseleko olukhuselekileyo xa i-lens ibotshelelwe kwisakhelo kunye nezikhonkwane, ukukhusela ukuba ingatyi. Nangona kunjalo, lo msebenzi unokwandisa uxinzelelo lwe-lens, olukhokelela ekungakhululeki xa unxibile. Ubukhulu obugqithileyo bemilinganiselo yelensi okanye ukuqiniswa ngokugqithisileyo kwezikrufu zefreyimu kunokubangela ukuchaneka okungalinganiyo kumphezulu welensi, okukhokelela kwizambuku ezifana namaza kwaye kuchaphazele umgangatho womfanekiso.
I-Phenomenon ye-Eyeglass Stress Generation
1. I-Birefringence
Ngenxa yobukhulu obuncinci bokusila be-lens, ukuqiniswa ngexesha lenkqubo yokuhlanganisana kubangela ukuba indawo ye-peripheral ye-lens ixinzelelwe, okubangela ukwanda koxinzelelo. Olu tshintsho kuxinzelelo luguqula isalathiso sokuqala se-refractive ye-lens, ngaloo ndlela ibangela ukwenzeka kwe-"birefringence" kwilensi.
2. Igwetyiwe
Ukusabalalisa Ngexesha lenkqubo yokuhlanganisa i-eyeglass, ukuba ubungakanani buqinile kakhulu, kuya kubangela ukuba i-lens ixinzelelwe, ibangele "imibimbi" yomhlaba kwaye ibangele ukuchithwa kwe-lens.
Xa sijongene nemiba enjalo, sinokususa i-lens kwisakhelo ukuze sitshintshe imeko ecinezelweyo yelensi. Olu tshintsho luhlengahlengiso loxinzelelo lwexeshana, kwaye emva kokuba amandla angaphandle asusiwe, imeko yelensi inokukhululeka okanye ibuyiselwe ngokupheleleyo. Nangona kunjalo, kuyafaneleka ukuba uqaphele ukuba ukuba kukho utshintsho lwexesha elide loxinzelelo lwangaphakathi olubangelwa uxinzelelo lwangaphandle, nokuba i-lens iyachithwa kwaye ihlanganiswe, ayinakuqinisekisa ukubuyiselwa kwelensi kwimeko yayo yangaphambili. Kule meko, inketho yodwa kukukhetha ukwenza ngokwezifiso i-lens entsha.
Uxinzelelo lweLens luxhaphake kakhulu kwiiglasi zefreyimu epheleleyo, kwaye kwiiglasi ezingenami rimless, kunokwenzeka ukuba ucingo lwerim luqine kakhulu. Olu hlobo lwenzeka ludla ngokuvela kwindawo yeperipheral yelensi, kwaye uxinzelelo oluncinci lunempembelelo encinci kumgangatho wokubonwayo kwaye alubonakali lula. Nangona kunjalo, ukuba uxinzelelo lugqithise, luya kuchaphazela ummandla we-optical optical, okhokelela kumbono ophazamisayo kunye nokudinwa okubonakalayo, ngakumbi xa ujonga i-periphery okanye ngexesha lokuhamba kwe-scanning.
Ngenxa yokuba uxinzelelo lweglasi lubangelwa ikakhulu kukunyanzeliswa kwesakhelo, iiglasi ezingenasiphako zibonisa ukusebenza ngcono koxinzelelo.
I-Eyeglass Stress Self-test Indlela yokuzivavanya
Emva kokuthotyelwa kwamandla angaphandle, iilensi zezinto ezahlukeneyo ziya kuvelisa iipateni ezahlukeneyo zoxinzelelo ngenxa yokungafani kobuninzi, ubunzima, kunye nesakhiwo sangaphakathi. Nangona kunjalo, iziganeko zoxinzelelo zingenzeka kungakhathaliseki ukuba yintoni na into. Oku kulandelayo sisingeniso esifutshane kwindlela yokuvavanya uxinzelelo. Izixhobo ezifunekayo yi-monitor yekhompyutha kunye ne-polarized lens.
Indlela yokusebenza:
1. Qala ikhompyutha kwaye uvule uxwebhu lweLizwi elingenanto. (Uvavanyo loxinzelelo lufuna ukusetyenziswa kokukhanya kwepolarized, kwaye imonitha yekhompyuter ngumthombo oqhelekileyo wovavanyo loxinzelelo.)
2. Beka iiglasi phambi kwesikrini sekhompyuter kwaye ujonge ngenyameko ukubona ukuba kukho naziphi na izinto ezingaqhelekanga ezikhoyo.
3. Sebenzisa iilensi ze-polarized (ukhetho lubandakanya iiglasi zelanga ezipholileyo, iikliphu zelensi ezipholileyo, kunye neeglasi zefilimu ze-3D) ukujonga iipateni zoxinzelelo kwiilensi zeglasi kunye nekhompyutheni yekhompyutheni.
Iilensi ze-polarized zingabonakalisa ukuphambuka okunemigca kwindawo ye-peripheral ye-lens, okukubonakaliswa kweepateni zoxinzelelo. Ukuhanjiswa koxinzelelo kwiiglasi ngokuqhelekileyo kubonakala njengamanqaku oxinzelelo kunye nemimandla yoxinzelelo, kwaye iqondo leepateni zoxinzelelo lihambelana ngokusondeleyo nomphumo woxinzelelo lweeglasi. Ngokuhlalutya ukuhanjiswa kweepateni zoxinzelelo, sinokumisela ngokulula isalathiso sokunyanzeliswa kunye nobungakanani boxinzelelo oluye lwenziwa yi-lens ngexesha lenkqubo yokuhlanganisa.
Ekuhlolweni, i-lens yasekuqaleni ngaphambi kokuhlanganisana iqulethe iqondo elithile loxinzelelo ngokungabikho kwamandla angaphandle. Oku kubangelwa amandla angalinganiyo afana nokunyanzeliswa kunye nokunciphisa ngexesha lenkqubo yokuvelisa, okubangelwa uxinzelelo lwangaphakathi. Kuyafaneleka ukuba uqaphele ukuba ubukho boxinzelelo lwangaphakathi kwiiglasi zamehlo kunzima ukuphepha, kwaye ixabiso elincinci okanye elincinci leepateni zoxinzelelo liyamkeleka. Ngexesha elifanayo, iipatheni zoxinzelelo akufanele zihanjiswe kwiziko le-optical lens ukuphepha ukuchaphazela umgangatho obonakalayo.
Ukuququmbela
Iziphumo zoxinzelelo lwezibuko zamehlo zinokuba nefuthe kumgangatho wabo wokubonwayo, njengokungakhululeki xa unxibe kwaye usasazeke kwinkalo yembonakalo yeperipheral. Noko ke, sifanele siqonde ukuba imeko yoxinezeleko lweendondo zamehlo kunzima ukuyiphepha, yaye logama nje ikuluhlu olusengqiqweni, impembelelo yokubona isenokuphantse ibe yinto encinane. Iilensi ezilungiselelweyo zixhamla kwitekhnoloji yelathe, ekhokelela kwiimeko zoxinzelelo olusezantsi, kwaye ngoku ibeyeyona mveliso iphambili kwintengiso yamehlo ephezulu.
