Muraayadaha nadiifka ah ayaa ah kuwa ugu badan ee loo isticmaalo muraayadaha wax lagu saxo.Bixinta hufnaanta tayada sare leh, yaraynta milicsiga iftiinka, hagaajinta isbarbardhigga iyo kor u qaadida waxqabadka muuqaalka, shaqadoodu waa inay si raaxo leh u bixiyaan aragti cad.Muraayadaha saafiga ah waxay ku habboon yihiin kuwa xidha muraayadaha maalinta oo dhan maalin kasta.Waxa kale oo ay u fiican yihiin kuwa jecel muuqaalka ay xidhashada muraayadaha siisay, xitaa haddii ay indhahoodu aad u weyn yihiin.Eray ahaan, muraayadaha cad cad ayaa qof walba u fiican
Hopesun waxay bixisaa mid ka mid ah xulashooyinka ugu wanaagsan ee muraayadaha cad ee dhammaan agabyada laga bilaabo 1.50 index ilaa 1.74 index.Dhammaan muraayadaha ayaa laga sameeyay agabka ugu tayada wanaagsan adduunka, sida CR-39 ee ka socda PPG, MR taxane ah ee Kiimikooyinka Mitsui si loo hubiyo hufnaanta muraayadda, badbaadada, waarta.Hopesun waxay kaydisay tiro aad u badan iyo cadad lenses saafi ah oo la dhammeeyay oo hal aragti ah, laba geesood ah iyo horumar leh.

Haddii aad qiimeyso tayada, waxqabadka iyo hal-abuurka waxaad timid meeshii saxda ahayd.

CR39 (1.50 tusmada dib-u-celinta):CR39 waxaa lagu gartaa nambarka Abbe sare, daah-furnaan sare, iska caabin xoog leh (aan lahayn dahaar), cufnaanta hoose (qiyaastii kala badh ka yar muraayadda muraayadda), waxqabadka midabaynta wanaagsan, caabbinta dareeraha, caabbinta kiimikada iyo caabbinta kulaylka.Iyo sababta oo ah habka wax soo saarku waa qaan, qiimo jaban, ilaa hadda waa mid ka mid ah qalabka caadiga ah ee warshadaha muraayadaha.Si kastaba ha ahaatee, CR39 wuu ka jaban yahay qalabka kale marka loo eego iska caabbinta saamaynta iyo xoogga jilicsanaanta, markaa kuma habboona muraayadaha rim-la'aanta ah (lenses waxay u muuqdaan inay jabaan marka la qodayo), sidoo kale waxay leedahay index refractive-ka ugu hooseeya, taas oo ka dhigaysa muraayadaha dhumucyada heerarka sare.

1.56 Tusaha dib-u-celinta:Walxaha ceeriin badanaa waa NK55, kaas oo inta badan loo yaqaan akril.qiimuhu waa hooseeyaa heerka ka faa'iidaysiguna wuu sarreeyaa, laakiin dareenka iftiinka waa daciif.Lensku waa jajaban yahay, wayna fududahay in la jebiyo marka la qodayo faamka.

1.59 PC walxo:Qalabka kombuyuutarku waa Polycarbonate, kaas oo ah balaastiig heerkulbeeg ah oo leh index refractive of 1.59 iyo iska caabin xoog leh.Waxa loo isticmaali karaa sidii muraayadaha aanay xabbadu karin iyo koofiyada koofiyada ee goobta milatariga.Waxa loo isticmaali karaa muraayadaha iyada oo aan laga welwelin jebinta muraayadaha.Waxay ku habboon tahay muraayadaha aan rim lahayn.Iyo index refractive ayaa ka sarreeya CR39, muraayadda ayaa laga dhigi karaa mid khafiif ah.Laakiin sida maaddada thermoplastic, waxqabadkeeda farsamaynta iyo iska caabbinta kiimikada ma fiicna, dusha ma dahaarka ah sidoo kale waa sahlan tahay in la xoqo, xidho caabbinta.Intaa waxaa dheer, Abbe nambarkiisu waa 30, kaas oo 28 ka duwan CR39.

Waxyaabaha MR (1.60MR-8, 1.67MR-7, 1.74MR-174):MR™ waa taxanayaal dhexdhexaad ah iyo agab resin index refractive sare ah oo ay samaysay Shirkadda Kiimikada Mitsui ee Japan.Marka laga reebo MR174, taxanaha oo dhan wuxuu ka samaysan yahay maaddada polyurethane (MR174 waa maaddada baaruudka giraanta ah oo leh caabbinta fidinta wanaagsan).Inkasta oo iska caabbinta saameyntu aysan u fiicnayn sida PC iyo Trivex, waxay leedahay faa'iidooyin muuqda oo ka sarreeya CR39.Intaa waxaa dheer, tirada abbe ee qalabkan taxanaha ah waa dhexdhexaad, caabbinta kulaylka, caabbinta cimilada iyo caabbinta kiimikada waa wanaagsan tahay, sidaas darteed waxay leedahay waxqabad dhamaystiran oo wanaagsan.
