Muraayada Semi-dhammeeyay waa bannaan ceeriin ah oo loo isticmaalo in lagu soo saaro muraayadda RX ee ugu shaqsiyeysan sida ku cad warqadda daawada bukaanka.Awoodaha dawo ee kala duwan ayaa codsanaya noocyada muraayadaha ee dhammays tiran ee kala duwan ama qalooca salka.
Muraayadaha dhammayska tiran waxaa lagu soo saaraa hab wax shubid ah.Halkan, monomers dareere ah ayaa marka hore lagu shubaa caaryada.Walxaha kala duwan ayaa lagu daraa monomer-yada, tusaale ahaan wax-qabadeyaasha iyo kuwa UV-nuga.Bilawiyuhu waxa uu kiciyaa fal-celin kiimikaad oo u horseedda adkaanta ama "daawaynta" muraayadda, halka nuugeeyaha UV uu kordhiyo nuugista UV ee muraayadaha kana hortagayo hurdi.
Marka muraayadaha Photochromic ay soo bandhigaan iftiinka UV, trillions of photochromic molecules ee muraayadda ayaa bilaabaya inay beddelaan qaabdhismeedka.Falcelintani waa waxa sababa in lensyadu madoobaato.
Dhammaan muraayadaha ku habboon iftiinka waxay isticmaalaan molecules photochromic;Sarraynta tignoolajiyada sawir-qaadista ee Convox waxay ku jirtaa qaacidooyinkayada gaarka ah, ee patented.Unugyadan si joogto ah oo siman ayaa dib u habeynaya si qaddarka ugu fiican ee iftiinka uu gaaro indhahaaga haddii aad ku jirto iftiinka qoraxda, dabool daruuraha hoostiisa ama gudaha gudaha.
Gudaha
Soo celi midabka muraayadda hufan ee jawiga gudaha ee caadiga ah oo ilaali gudbinta iftiinka wanaagsan.
Banaanka
Iftiinka qorraxda hoostiisa, midabka muraayadda midabka beddeleysa waxay noqotaa bunni/cawlan si ay u xannibto fallaadhaha ultraviolet una ilaaliso indhaha.
Mid ka mid ah muraayadaha ayaa leh saddex hawlood, midab maskaxeed.
Lens-ku wuxuu qaataa tignoolajiyada midabaynta degdega ah ee fiber indhaha si uu u sameeyo isbedel degdeg ah oo lagu sameeyo fallaadhaha iftiinka kala duwan, si qofka xidhani uu ugu raaxaysto inuu ku raaxaysto gelitaanka jawiga u dhigma ee xaaladaha midabka ku habboon.Isla markaaba midab bay isku beddeshaa qorraxda hoosteeda, kan ugu madawna waa isla midabka mugdiga ah ee muraayadaha qorraxda, iyadoo la hubinayo isbeddelka midabka leniska, midabka dhexe iyo cidhifka muraayaddana waa mid joogto ah.Isbarbardhigga naqshadeynta aspheric iyo shaqada ka-hortagga dhaldhalaalka, way caddahay, iftiin badan tahay oo raaxo badan in la xidho.
Isku darka myopia iyo muraayadaha qorraxda oo la mid ah, waxay xallin kartaa dhibaatada myopia aan caddayn, waxayna xannibi kartaa fallaadhaha ultraviolet waxayna leedahay qiimo aad u sarreeya, taas oo ka qurux badan kana fudud.
Si xor ah u habayn naqshadda qaloocan ee weyn, curvatures kala duwan si ay ugu habboonaato moodada iyo xayndaabka ciyaaraha, si loo daboolo baahiyaha gaarka ah iyo kuwa gaarka ah ee isticmaalaha;noocyo kala duwan oo kala duwan oo ka mid ah xulashooyinka filimka midabaynta midabaynta si aad ula kulanto raadinta midabkaaga.
