    Waqtigan xaadirka ah, waxaa jira laba nooc oo ah qalabka muraayadaha ee suuqa, mid waa walxo dhalada ah, kan kalena waa maaddada resin. Qalabka xabagta ayaa loo qaybiyaa CR-39 iyo polycarbonate (wax PC).

    Muraayadaha bifocal ama lenses bifocal waa muraayado ka kooban laba goobood oo sixid isku mar ah waxaana inta badan loo isticmaalaa in lagu saxo presbyopia. Meesha fog ee lenska laba-geesoodka ah lagu saxo waxa lagu magacaabaa aagga fog, aagga u dhowna waxa loo yaqaannaa aagga u dhow iyo goobta akhriska. Sida caadiga ah, gobolka fogfog waa weyn yahay, sidaas darteed waxaa sidoo kale loo yaqaan filimka ugu weyn, iyo gobolka u dhow waa yar yahay, sidaas darteed waxaa loo yaqaan 'sub-film'.

    Muraayada muraayadda muraayadda midab beddelka leh waxay ka kooban tahay qaddar go'an oo koloriin qalin ah, dareenka iyo naxaasta. Marka la eego xaaladda iftiinka hirarka gaaban, waxa loo kala qaybin karaa atamka qalinka ah iyo atamka koloriinta. Atamyada chlorine waa mid aan midab lahayn, atamka qalinka ahna waa midab. Isku-duubnaanta atamka qalinku wuxuu samayn karaa xaalad kolloid ah, taas oo ah waxa aan u aragno midabka muraayadda. Sida ay u xoog badan tahay iftiinka qoraxda, atomiyada qalinka badan ayaa kala soocaya, muraayada madow ayaa noqon doonta. Sida ay u daciifto iftiinka qoraxda, atomiyada lacagta yar ayaa la kala saarayaa, muraayada iftiinka ayaa noqon doonta. Ma jiro qorrax toos ah qolka, markaa muraayadaha ayaa noqda mid aan midab lahayn.
