1.71 Muraayadaha indhaha ee hal-aragga ah ee HMC
Muraayad 1.71 Magaca buuxa Muraayad tusmada refractive 1.71, oo leh tusmada refractive sare, gudbinta sare, astaamaha tirada Abbe oo sarreeya, marka la eego heerka myopia oo isku mid ah, waxay si weyn u yareyn kartaa dhumucda muraayadda, waxay yareyn kartaa tayada muraayadda, isla markaana waxay ka dhigi kartaa muraayadda mid saafi ah oo dhalaalaya, oo aan si fudud loo kala bixin karin qamadiga qaanso roobaadka. Waxaa la ogaaday in ku darista resin sulfide wareeg ah walxaha muraayadda ay hagaajin karto tusmada refractive ee muraayadda, laakiin resin sulfide wareeg ah oo aad u badan ayaa horseedi doonta hoos u dhaca gudbinta iftiinka iyo dildilaaca walxaha. Iyadoo si sax ah loo xakameynayo waxa ku jira resin sulfur giraanta ee resin 1.71KR, muraayadda 1.71 waxay gaartaa tusmada refractive sare iyo lambarka abbe iyadoo la hubinayo gudbinta iftiinka wanaagsan, kala firdhinta hoose iyo aragti cad.

1.56 HMC Aragtida Keli ah
Muraayadaha, muraayadda waxaa sidoo kale loo yaqaan xarunta muraayadda, waa xarunta rinjiyeynta ka dib marka la rakibo, oo ku habboon in lagu dhejiyo muraayadda, sidaas darteed waxaa loogu yeeraa xarunta muraayadda. Qaabkeedu wuxuu noqon karaa mid toosan, mid toosan, waa rakibid fudud oo ku habboon.
Kala-soocidda: Muraayadaha waxaa loo qaybin karaa afar nooc oo soo socda iyadoo loo eegayo agab kala duwan:
Muraayadaha Resin-ka ee muraayadaha gaarka ah ee muraayadaha booska muraayadda galaaska

1.49 Aragtida Hal-hal ah ee UC
Tusmada Refractive ee muraayadda, 1.49, 1.56, 1.60, 1.67, 1.71, 1.74 ee ku taal calaamadda sare ee muraayadda waxay tilmaamaysaa tusmada Refractive ee muraayadda. Muraayadaha Myopia, marka tusmada Refractive ee muraayadda ay sarreyso, ayaa geeska muraayadda ka khafiifsan, iyadoo la tixgelinayo in xuduudaha kale ay isku mid yihiin.

Muraayadaha Qorraxda ee CR39
Muraayadaha qorraxda waa nooc ka mid ah alaabada daryeelka aragga si looga hortago waxyeelada soo gaarta indhaha aadanaha ee ka dhalata iftiinka qorraxda oo xooggan. Iyadoo la horumarinayo heerka agabka iyo dhaqanka dadka, muraayadaha qorraxda waxaa loo isticmaali karaa agab gaar ah oo loogu talagalay quruxda ama qaabka shaqsiyeed.

Muraayadaha indhaha ee MR-7 FSV ee HMC ee Heerka Sare leh
Muraayadaha tusmada 1.67 badanaa waxay leeyihiin laba nooc oo agab ah, walxaha MR-7 iyo walxaha MR-10.
Laakiin agabka MR-7 waa agabka ugu isticmaalka badan uguna caansan marka loo eego agabka MR-10.

1.59 Muraayadaha indhaha ee Polycarbonate HMC
Muraayadaha resin-ka guud waa walxo adag oo kuleyl ah, taas oo ah, walxaha ceeriinku waa dareere, muraayadaha adagna waxaa la sameeyaa ka dib marka la kululeeyo. Muraayadaha PC-ga, oo sidoo kale loo yaqaan "muraayadaha hawada sare", "muraayadaha cosmic", oo kiimiko ahaan loogu yeero polycarbonate, waa walxo thermoplastic ah.

1.56 Muraayadaha indhaha ee Bifocal Fidsan / Sare Wareegan / Muraayadaha indhaha ee HMC ee isku dhafan
Muraayadaha Bifocals waa muraayadaha muraayadaha oo ka kooban labada aag ee sixitaanka waxaana ugu horreyn loo isticmaalaa sixitaanka presbyopia. Meesha ay bifocals-ku saxaan aragtida fog waxaa loo yaqaan aagga aragtida fog, meesha saxda ah ee u dhow aragtida waxaa loo yaqaan aagga aragtida dhow iyo aagga akhriska. Badanaa, aagga fog waa weyn yahay, sidaas darteed waxaa sidoo kale loo yaqaan qaybta ugu weyn, aagga u dhowna waa yar yahay, oo loo yaqaan qaybta hoose.

1.56 Muraayadaha indhaha ee Porgressive HMC
Muraayadaha Horumarka leh waa muraayad dherer badan leh, oo ka duwan muraayadaha akhriska dhaqameed iyo muraayadaha akhriska bifocal. Muraayadaha horusocodka leh ma laha daalka indhaha ee ah inay si joogto ah u hagaajiyaan dhererka diiradda marka la isticmaalayo dhererka bifocal, mana jirto xariiq cad oo u dhaxaysa labada dherer ee diiradda. Khadka kala-soocidda. Waa raaxo in la xidho waxayna leedahay muuqaal qurux badan, waxayna si tartiib tartiib ah u noqotay doorashada ugu fiican ee dadka qaba presbyopia.
