Iilensi ziqhelekile kubantu abaninzi, kwaye zidlala indima enkulu ekulungiseni i-myopia kwiiglasi. Iilensi zineelensi ezahlukeneyo zokugquma, ezifana nokugquma okuluhlaza, ukugquma okuluhlaza okwesibhakabhaka, ukugquma okuluhlaza okwesibhakabhaka, kwanokwagquma kwegolide yodidi oluphezulu. Ukuguguleka nokukrazuka kweelensi zokugquma sesinye sezizathu eziphambili zokutshintsha iiglasi zamehlo, ngoko ke makhe sifunde ngakumbi malunga neelensi zokugquma.
Uphuhliso lwe-lens coating
Ngaphambi kokuba kuvele iilensi ze-resin, iilensi zeglasi zazisetyenziswa kakhulu. Iingenelo zeelensi zeglasi zi-refractive index ephezulu, i-high light transmittance, kunye nobunzima obuphezulu, kodwa zikwanazo neengxaki ezifana nokuqhekeka, ubunzima, kunye nokungakhuseleki.
Ukujongana neengxaki zeelensi zeglasi, iifektri ziye zaphuhlisa izinto ezahlukeneyo zokutshintsha iilensi zeglasi, kodwa akukho nanye efanelekileyo. Isixhobo ngasinye sineenzuzo kunye neengxaki zaso, kwaye kunzima ukufikelela kwibhalansi. Oku kukwasebenza nakwiilensi zeresin zangoku (izinto zeresin).
Kwiilensi ze-resin zangoku, ukugquma yinkqubo efunekayo. Izinto ze-resin nazo zineendlela ezininzi zokwahlulahlula, ezifana ne-MR-7, i-MR-8, i-CR-39, i-PC, i-NK-55-C, kunye nezinye izinto ezininzi ze-resin, nganye ineempawu ezahlukeneyo. Nokuba yilensi yeglasi okanye ilensi ye-resin, ukukhanya okudlula kumphezulu welensi kuya kudlula kwiimeko ezahlukeneyo zokukhanya: ukubonakalisa, ukurhawuzelelwa, ukufunxwa, ukusasazeka, kunye nokudluliselwa.
Ukugquma ilensi ngefilimu engabonisi kukhanya
Ngaphambi kokuba ukukhanya kufike kumphezulu welensi, kuphelela kukukhanya okupheleleyo, kodwa xa kuphuma kwilensi kungene elisweni, akusekho kukhanya okupheleleyo. Okukhona ipesenti yamandla okukhanya iphezulu, kokukhona ukuhanjiswa kokukhanya kubhetele, kwaye kokukhona umgangatho womfanekiso kunye nesisombululo siphezulu.
Kwizinto ezithile zelensi, ukunciphisa ukulahleka kokukhanya yindlela eqhelekileyo yokwandisa ukuhanjiswa kokukhanya. Okukhona ukukhanya okukhanyayo, kokukhona ukuhanjiswa kwelensi kuncipha, nto leyo ebangela umgangatho ophantsi womfanekiso. Ke ngoko, ukunciphisa ukubonakaliswa kuye kwaba yingxaki ekufuneka isonjululwe ziilensi ze-resin, kwaye ifilimu echasene nokukhanya (ifilimu ye-AR) isetyenzisiwe kwilensi (ekuqaleni, kwakusetyenziswa iingubo ezichasene nokukhanya kwezinye iilensi ze-optical).
Ifilimu echasene nokukhanya isebenzisa umgaqo wokuphazamiseka ukuze ifumane ulwalamano phakathi kokukhanya okubonakalayo kwelensi egqunywe ngefilimu echasene nokukhanya kunye nobude bokukhanya kwesiganeko, ubukhulu beleya yefilimu, isalathisi sokukhanyela kweleya yefilimu, kunye nesalathisi sokukhanyela kweleya, okuvumela ukukhanya okudlula kwileya yefilimu ukuba kurhoxise omnye komnye, kunciphisa ukulahleka kwamandla okukhanya kumphezulu weleya kunye nokuphucula umgangatho womfanekiso kunye nesisombululo.
Iingubo ezichasene nokukhanya zihlala zisebenzisa ii-oxide zesinyithi ezicocekileyo kakhulu ezifana ne-titanium dioxide kunye ne-cobalt oxide, ezifakwa kumphezulu welensi ngenkqubo yokuphuma komoya (i-vacuum deposition) ukuze kufezekiswe iziphumo ezilungileyo zokuchasene nokukhanya. Iingubo ezichasene nokukhanya zihlala zishiya iintsalela, kwaye uninzi lweeleya zefilimu zikwimibala eluhlaza kakhulu.
Umbala wefilimu engabonisi kukhanya ungalawulwa, umzekelo, ukuvelisa ifilimu eluhlaza okwesibhakabhaka, ifilimu eluhlaza okwesibhakabhaka, ifilimu eluhlaza okwesibhakabhaka, ifilimu engwevu, njl. Iileya zefilimu ezinemibala eyahlukeneyo zinomahluko kwinkqubo yokwenziwa. Umzekelo, ifilimu eluhlaza okwesibhakabhaka ithetha ukuba ukukhanya okuphantsi kufuneka kulawulwe, kwaye ubunzima bokugquma bukhulu kunobo befilimu eluhlaza. Nangona kunjalo, umahluko ekudlulisweni kokukhanya phakathi kweefilimu eziluhlaza okwesibhakabhaka neziluhlaza unokuba ngaphantsi kwe-1%.
Kwiimveliso zelensi, iifilimu eziluhlaza okwesibhakabhaka zihlala zixhaphake kakhulu kwiilensi eziphakathi ukuya kweziphezulu. Ngokomgaqo, ukuhanjiswa kokukhanya kweefilimu eziluhlaza okwesibhakabhaka kuphezulu kunokweefilimu eziluhlaza (qaphela ukuba oku ngokomgaqo) kuba ukukhanya ngumxube wee-wavelengths ezahlukeneyo, kwaye ii-wavelengths ezahlukeneyo zineendawo ezahlukeneyo zokuthatha imifanekiso kwi-retina. Kwiimeko eziqhelekileyo, ukukhanya okumthubi-luhlaza kuthathwa umfanekiso ngokuchanekileyo kwi-retina, kwaye ulwazi olubonakalayo olunikezelwa kukukhanya okuluhlaza luphezulu, ngoko ke iliso lomntu livakalelwa kukukhanya okuluhlaza.
Ukugquma ilensi ngefilimu eqinileyo
Ukongeza ekudlulisweni kokukhanya, zombini izinto ze-resin kunye neglasi zineengxaki ezibalulekileyo: iilensi azinzima ngokwaneleyo.
Isisombululo kukusombulula oku ngokongeza i-coating eqinileyo yefilimu.
Ubunzima bomphezulu weelensi zeglasi buphezulu kakhulu (ngokubanzi kushiya amabala amancinci xa zikrwelwa zizinto eziqhelekileyo), kodwa oku akunjalo kwiilensi zeresin. Iilensi zeresin zikrwelwa lula zizinto eziqinileyo, nto leyo ebonisa ukuba azigugi.
Ukuphucula ukumelana nokuguguleka kwelensi, kuyimfuneko ukongeza i-hard film coating kumphezulu welensi. I-hard film coatings idla ngokusebenzisa ii-athomu ze-silicon ukulungisa ukuqina, kusetyenziswa isisombululo sokuqina esine-organic matrix kunye nee-inorganic ultrafine particles kuquka izinto ze-silicon. I-hard film ngaxeshanye inobunzima kunye nobunzima (umaleko wefilimu kumphezulu welensi uqinile, kwaye i-substrate yelensi ayiqhekeki kangako, ngokungafaniyo neglasi eqhekeka lula).
Eyona teknoloji iphambili yanamhlanje yokugquma ifilimu eqinileyo kukuntywiliselwa. Ukugquma ifilimu eqinileyo kukhulu, malunga ne-3-5μm. Kwiilensi ze-resin ezineengubo zefilimu eqinileyo, zinokubonwa ngesandi sokucofa kwi-desktop kunye nokukhanya kombala welensi. Iilensi ezivelisa isandi esicacileyo kwaye ezinemiphetho eqaqambileyo ziye zanyangwa ngokuqina.
Ukugquma ilensi ngefilimu yokuthintela ukungcoliswa.
Ifilimu echasene nokukhanya kunye nefilimu eqinileyo zezona zinto zimbini ziphambili zokugquma iilensi ze-resin okwangoku. Ngokubanzi, ifilimu eqinileyo igqunywa kuqala, ilandelwe yifilimu echasene nokukhanya. Ngenxa yemida ekhoyo ngoku yezinto zefilimu ezichasene nokukhanya, kukho ukungangqinelani phakathi kwamandla okuchasene nokukhanya kunye nokungangcolisi. Ngenxa yokuba ifilimu echasene nokukhanya ikwimeko yokuvuleka, ithambekele kakhulu ekwenzeni amabala kumphezulu welensi.
Isisombululo kukongeza umaleko owongezelelweyo wefilimu ethintela ukungcola phezu kwefilimu ethintela ukungcola. Ifilimu ethintela ukungcola yenziwe ikakhulu yi-fluoride, enokugubungela umaleko wefilimu ethintela ukungcola, inciphise indawo yokunxibelelana phakathi kwamanzi, ioyile, kunye nelensi, ngelixa ingatshintshi ukusebenza kwefilimu ethintela ukungcola.
Njengoko iimfuno zisanda ngokwanda, kuye kwaveliswa iileya zefilimu ezisebenzayo, ezifana nefilimu edibanisayo, ifilimu echasene nokuma, ifilimu yokukhusela ukukhanya okuluhlaza okwesibhakabhaka, ifilimu echasene nokugqwala, kunye nezinye iileya zefilimu ezisebenzayo. Izinto zelensi ezifanayo, isalathisi sokuqaqamba kwelensi efanayo, iimpawu ezahlukeneyo, kwaye nangaphakathi kwelensi efanayo, kunye nezinto ezifanayo, uthotho lweelensi ezahlukeneyo lunomahluko wamaxabiso, kwaye iilensi zokugquma zesinye sezizathu. Kukho umahluko kubuchwepheshe kunye nomgangatho weengubo.
Kwiintlobo ezininzi zeengubo zefilimu, kunzima kumntu oqhelekileyo ukubona umahluko. Nangona kunjalo, kukho uhlobo olunye lwengubo apho iziphumo zinokubonwa lula: iilensi ezivimba ukukhanya okuluhlaza okwesibhakabhaka (iteknoloji esetyenziswa kakhulu kwiilensi ezivimba ukukhanya okuluhlaza okwesibhakabhaka ezikumgangatho ophezulu).
Ilensi evimba ukukhanya okuluhlaza okwesibhakabhaka efanelekileyo ihluza ukukhanya okuluhlaza okwesibhakabhaka okuyingozi kuluhlu lwe-380-460nm ngokusebenzisa umaleko wefilimu evimba ukukhanya okuluhlaza okwesibhakabhaka. Nangona kunjalo, kukho umahluko ekusebenzeni kwenyani phakathi kweemveliso ezivela kubavelisi abahlukeneyo. Iimveliso ezahlukeneyo zibonisa umahluko ekusebenzeni kokuthintela ukukhanya okuluhlaza okwesibhakabhaka, umbala osisiseko, kunye nokudluliselwa kokukhanya, okukhokelela ngokwendalo kumaxabiso ahlukeneyo.
Ukukhusela ukugquma kwelensi
Iilensi zokugquma zinobuthathaka kumaqondo obushushu aphezulu. Iilensi zokugquma ezikwii-resin zifakwa kamva kwaye zonke zinobuthathaka obufanayo: zinobuthathaka kumaqondo obushushu aphezulu. Ukukhusela iilensi zokugquma kungandisa ubomi beelensi. Ezi ndawo zilandelayo zinokubangela umonakalo kwiilensi zokugquma:
1. Ukubeka iiglasi kwideshibhodi yemoto emini ehlotyeni.
2. Ukunxiba iiglasi okanye ukuzibeka kufutshane ngelixa usebenzisa i-sauna, uhlamba, okanye ucwilisa emanzini ashushu.
3. Ukupheka ekhitshini kumaqondo obushushu aphezulu eoyile; ukuba ioyile eshushu itshiza kwiilensi, zinokuqhuma ngoko nangoko.
4. Xa usitya imbiza eshushu, ukuba isuphu eshushu itshiza kwiilensi, zinokuqhuma.
5. Ukushiya iiglasi kufutshane nezixhobo zasekhaya ezivelisa ubushushu ixesha elide, ezifana nezibane zedesika, oomabonakude, njl.njl.
Ukongeza kwezi ngongoma zingasentla, kubalulekile ukuba ungangeni kwi-asidi okanye i-alkaline liquids enamandla ukuthintela ukuba iifreyimu okanye iilensi zingadli.
Ukuqhuma kweelensi kunye nemikrwelo kwahlukile ngokupheleleyo. Ukuqhuma kubangelwa kukuvezwa kumaqondo obushushu aphezulu okanye ulwelo lweekhemikhali, ngelixa imikrwelo ibangelwa kukucocwa okungafanelekanga okanye ukuchaphazeleka ngaphandle.
Enyanisweni, iiglasi zizinto ezithambileyo. Ziyakhawuleza ukuxinwa, ukuwa, ukugoba, amaqondo obushushu aphezulu, kunye nolwelo olubolayo.
Ukukhusela ukusebenza kwe-optical kwe-film layer, kuyimfuneko:
1.Xa ukhulula iiglasi zakho, zibeke kwindawo yokukhusela uze uzigcine kwindawo apho abantwana bangenakukwazi ukufikelela khona.
2.Coca iiglasi ngesepha exutyiweyo nengathathi cala usebenzisa amanzi abandayo. Akukhuthazwa ukusebenzisa naluphi na olunye ulwelo ukucoca iiglasi.
3.Kwiindawo ezishushu kakhulu (ingakumbi xa uhlamba okanye upheka), kuyacetyiswa ukuba unxibe iiglasi ezindala ukuthintela ukonakala kweelensi zeeglasi ezintsha.
Abanye abantu banokuhlamba iiglasi zabo ngamanzi afudumeleyo ngelixa behlamba iinwele zabo, ubuso, okanye behlamba ukuze iiglasi zicoceke. Nangona kunjalo, oku kunokubangela umonakalo omkhulu kwiingubo zeelensi kwaye kunokwenza iilensi zingasebenzi. Kubalulekile ukugxininisa ukuba iiglasi kufuneka zicocwe kuphela ngesepha engathathi cala exutywe namanzi abandayo!
Ukuququmbela
Ngenxa yokuqhubela phambili okuqhubekayo kwetekhnoloji yokugquma, iimveliso zamehlo zanamhlanje zenze inkqubela phambili enkulu ekudluliseleni ukukhanya, ukumelana nokukrwela, kunye neempawu zokulwa nokungcola. Uninzi lweelensi ze-resin, iilensi zePC, kunye neelensi ze-acrylic zinokuhlangabezana neemfuno zabantu zemihla ngemihla ngokubhekiselele kuyilo lokugquma.
Njengoko kukhankanyiwe apha ngasentla, iiglasi zamehlo ziimveliso ezibuthathaka kakhulu, ezinxulumene netekhnoloji yokugquma yomaleko wefilimu, ingakumbi iimfuno eziphezulu zokusetyenziswa kobushushu.
