Ilensi yangokwezifiso yegaraji ebizwa ngokuthi yisiqephu segaraji, isethi yokukhiqiza.Ilensi eyenziwe ngokwezifiso yegaraji isho umkhiqizo ongakwazi ukuhlangatshezwa wukunikezwa kwezingcezu ezikhona futhi usetshenziselwa ukuhlangabezana nezidingo ezikhethekile.Lolu hlobo lwamalensi luhlukile kumalensi avamile avamile, angakwazi ukufeza ukukhiqizwa ngobuningi.Amalensi egalaji enziwe ngokwezifiso angahlinzeka ngezixazululo ezibukwayo ezibanzi, njengamalensi e-myopia enziwe ngokwezifiso ukuze enze unqenqema lube luhle futhi anciphise ukushuba konqenqema lwamalensi, amalensi enziwe ngokwezifiso ukuze avumelane nokugoba okukhethekile kohlaka, ifilimu ekhethekile, amalensi amakhulu akhethekile, aqhubekayo. amalensi ama-multifocal, ama-prism lens, njll.

Ukusetshenziswa kwamalensi ngokwezifiso egaraji
1. Ukucutshungulwa okukhethekile kwe-photometric: njenge-myopia ephezulu, i-hyperopia ephezulu, i-astigmatism ephezulu, amalensi akhethekile eprism, njll. Isibonelo, ukukhanya okuphezulu kakhulu kwelensi eyinegethivu kwakungu -24.00DS kanti lokho kwesibuko sekholomu ehlanganisiwe kwaba ngu--4.00D.Amalensi e-Ortho enziwe ngezifiso aze afike ku-+13.00DS.Isibuko sekholomu esihlanganisiwe singenziwa ngezifiso ukuze sibe +6.00DC.
2. Ukucutshungulwa kwendawo okukhethekile: eyindilinga, i-aspherical, i-aspherical enezinhlangothi ezimbili, ukucutshungulwa kwelensi eqhubekayo enokukhanya okuhlukile, ukwakheka okuhlukile kwendawo eqhubekayo, kanye nomklamo oqhubekayo oqhubekayo wangaphakathi nangaphandle.Ngenxa yokuthi idizayini yelensi yezinhlobo ezihlukene zobuso izoletha imizwa ehlukene yokubuka, inganikeza izixazululo ezihambisanayo kubantu abanezidingo ezihlukile zokubuka.
3. Ifilimu yokugqoka ekhethekile;Ukuze kuzuzwe izidingo ezahlukene ngokwezifiso ifilimu ekhethekile.Isibonelo, engeza ifilimu ye-dural, ifilimu ye-anti-antireflection, ifilimu ye-hydrophobic, njll.
4. Ukwenza i-Mei-thin machining: I-Mei-thin machining ilensi enobubanzi obukhethekile obucacisiwe, eyenziwe ngokwezifiso ukuze kuncishiswe ukujiya kwesikhungo selensi ephozithivu kanye nogqinsi lomkhawulo welensi eyinegethivu.Amalensi akhiwe ngokwezifiso akhiwe ngomshini.Ngokwencwadi kadokotela kanye nokuma nobukhulu bohlaka, ubuchwepheshe bokucubungula obunogqinsi olungcono kakhulu luyamukelwa, futhi ukushuba okunengqondo kakhulu kwelensi kubalwa isofthiwe yobuchwepheshe, ukuze wenze izibuko zibe zinhle kakhulu.Imvamisa, isistimu yokwenza ngokwezifiso i-lens yegalaji ingafinyelela izidingo zobuhle nobuncane belensi ngokuklama kobubanzi, i-eccentricity design, i-lens surface system design nokunye.
5. Ukudaya ukucutshungulwa: ngokwezidingo ezihambisanayo, umbala ogcwele, umbala oqhubekayo, umbala ngamunye, ukudaya kokukhanya kwe-polarized nokunye ukucutshungulwa.
6. Isisekelo esikhethekile selensi egobile: yenza ngokwezifiso ilensi ekhethekile egobile ukuze ivumelane nohlaka olukhethekile lokugoba.Isibonelo, abantu bemfashini basebenzisa amafreyimu elanga ukuze benze izibuko zelanga ezimyopic.Ngokomumo wozimele kanye nedatha kadokotela ye-Optometry, siza ogqokile ukuthi adizayine i-lens surface bend enengqondo, enze ilensi ifane nohlaka, ukuze ogqokile akwazi ukwethula umphumela wokugqoka ophelele.Isibonelo, kulensi efanayo ye-+4.00D, indawo engaphambili yokujika kwe-+500 kanye nengemuva le--100 turn ingakhethwa, futhi indawo engaphambili yokujika kwe-+600 kanye nobuso obungemuva bokujika -200 nakho kungakhethwa. .Ukuma nokuqina komphetho welensi kuhluke ngokuphelele phakathi kwalezi zinhlelo ezimbili.

Inqubo yokukhiqiza ilensi yangokwezifiso egaraji
Inqubo ikakhulukazi ihlanganisa ukuqoqwa kwe-oda, ukubalwa kwedatha eyisisekelo, ukukhethwa kwemikhiqizo eseqediwe kancane, ukuqinisekiswa kwedatha eyisisekelo, ukubalwa kokuma kwendawo yangemuva, ifilimu evikelayo ekugobeni kwesisekelo, ukukhethwa kwesikhunta, i-sucker engaguquki, ukugaya okungalungile ukuma kwendawo engemuva, ukugaya okuhle nokupholishwa kwendawo yangemuva, ukuhlola ukuthulula, ukudaya kanye nefilimu eqinile, ukuhlolwa kwekhwalithi yokugcina, ukulethwa nezinye izinqubo.

Amanothi Okwenza Ngokwezifiso
1. Kunconywa ukuthi womabili amalensi enziwe ngokwezifiso noma nini lapho kunokwenzeka.Isibonelo, esimweni se-anisometropia, ilensi eyodwa -8.00DS yenziwe ngendlela oyifisayo nge-high refractive index lens, kanti ilensi eyodwa -4.00DS iyilensi evamile engeyona eyenzelwe ngokwezifiso.Kulesi simo, ukujiya okumaphakathi, umbala wangemuva welensi kanye nomthelela wokubonwayo kungase kwehluke phakathi kwelensi eyenziwe ngokwezifiso kanye nelensi engenziwanga ngendlela oyifisayo.Ngakho-ke, ngokombono wempilo ebonakalayo, kunconywa ukusebenzisa igaraji elifanayo ukuze wenze ngokwezifiso amalensi uma kungenzeka.
2. Mayelana negalaji, ugqinsi, ubukhulu besikhungo se-lens ngenxa yamalensi akhanya kakhulu, ikakhulukazi ilensi yegalaji ye-myopia ephezulu esebenzisa ukukhiqizwa kokugaya, ngokusebenzisa ilensi emaphakathi nendawo yokuqina komkhiqizo wokugaya ngokuqinisekile kuzoba ugqinsi ngokukhiqizwa kwesikhunta, ngoba uma umhlabathi mncane, ukukhanya kokuqala kungase kungakwazi ukulawula, i-lens yesibili iphuka kalula.
