Ngesiqhelo, iiglasi zelanga zinezi zinto zilandelayo:
1. I-resin lens lens material: I-resin yikhemikhali yekhemikhali ene-phenolic structure. Iimpawu: ubunzima obukhanyayo, ukumelana nobushushu obuphezulu, ukumelana nefuthe elinamandla, kwaye kunokuthintela ngokufanelekileyo imitha ye-ultraviolet.
2. Izinto ze-nylon lens Lens: zenziwe nge-nylon, iimpawu: i-elasticity ephezulu kakhulu, i-optical quality egqwesileyo, ukuchasana kwempembelelo enamandla, ngokuqhelekileyo isetyenziswa njengezinto ezikhuselayo.
3. I-Carbonated polyester lens (i-PC lens) izinto zelensi: ezomeleleyo, akukho lula ukuphuka, ukumelana neempembelelo, izinto ezikhethiweyo ezikhethekileyo kwiiglasi zezemidlalo, ixabiso liphezulu kunelo le-acrylic lens.
4. I-Acrylic lens (i-AC lens) izinto zelensi: Inokuqina okugqwesileyo, ubunzima obulula, imbono ephezulu kunye ne-anti-inkungu elungileyo.
Intshayelelo yeMveliso
Iingcali zamehlo zicebisa ukuba usoloko unxibe iindondo zelanga ukuze ukhusele amehlo akho; oku kungenxa yokuba i-eyeball yethu (i-lens) ilula kakhulu ukufunxa imitha ye-ultraviolet, kwaye umonakalo wemitha ye-ultraviolet uneempawu ezimbini ezibalaseleyo:
1.Umonakalo wemitha ye-ultraviolet iya kuqokelela. Ekubeni ukukhanya kwe-ultraviolet kukukhanya okungabonakaliyo, kunzima ukuba abantu baqonde intuitively.
2. Umonakalo wemisebe ye-ultraviolet emehlweni ayinakuguqulwa, oko kukuthi, ayinakulungiswa. Njenge: utyando lwecataract lunokutshintshwa kuphela iilensi ze-intraocular. Umonakalo wexesha elide kwiliso unokukhokelela ngokulula kumonakalo kwi-cornea kunye ne-retina, i-clouding ye-lens de i-cataract yenzeke, okukhokelela kumonakalo obonakalayo osisigxina.
Ekubeni umonakalo wemisebe ye-ultraviolet emehlweni ungabonakali, awukwazi ukuvakalelwa ngokukhawuleza. Ukuba awunxibi ziglasi, awuziva ungonwabanga ngakumbi. Kuthetha nje ukuba amehlo akho akakhathali kakhulu kukukhanya okubonakalayo (okufana nokubengezela kokubengezela, ilitha, kunye nokukhanya okubonakalayo). , kwaye ayikwazi ukuphepha umonakalo we-UV.
Ngaba okukhona zimnyama iindondo zelanga, kokukhona ngcono isiphumo sothintelo lwe-UV?
Hayi, umsebenzi we-lens ukuthintela imisebe ye-ultraviolet kukuba iphathwa yinkqubo ekhethekileyo (yongeza i-powder ye-UV) ngexesha lenkqubo yokuvelisa, ukwenzela ukuba i-lens ikwazi ukufumana ukukhanya okuyingozi ngaphantsi kwe-400NM njengemitha ye-ultraviolet xa ukukhanya kungena. Ayinanto yakwenza nobunzulu befilimu.
