Faa'iidooyinka
Walxaha sawir-qaadista waxaa lagu daraa walxaha ceeriin ee monomer-ka inta lagu jiro wax soo saarka, taasoo keentay in wakiilada si siman loogu qaybiyo muraayadda oo dhan. Naqshaddani waxay bixisaa laba faa'iido oo muhiim ah: saameyn sawir-qaadis oo waarta iyo iska caabin heerkul sare leh.
Qasaarooyinka
Qasaaro A: Kala duwanaanshaha midabka ee muraayadaha awoodda sare leh
Farqiga midabka ayaa laga yaabaa inuu ka dhex dhaco bartamaha iyo geesaha muraayadaha awoodda sare leh, iyadoo farqiga uu sii muuqanayo marka diopter-ku sii kordho.Sida caadiga ah loo yaqaan, dhumucda geeska muraayadda ayaa si weyn uga duwan dhumucdeeda dhexe - farqigan jireed wuxuu horseedaa kala duwanaanshaha midabka la arkay. Si kastaba ha ahaatee, inta lagu jiro ku habboonaanta muraayadaha, muraayadaha waa la jaraa oo la farsameeyaa si loo isticmaalo qaybta dhexe. Muraayadaha leh awood dhan 400 oo diopters ama ka hooseeya, farqiga midabka ee uu keeno sawir-qaadista ayaa ah mid aan la dareemi karin muraayadaha ugu dambeeya ee la dhammeeyay. Intaa waxaa dheer, muraayadaha sawirka-kormeerka ee tirada badan ee lagu sameeyay habkan waxay sii wadaan waxqabad guud oo heer sare ah ilaa laba sano.
Qasaaro B: Kala duwanaanshaha Badeecada Xaddidan
Kala duwanaanshaha alaabta muraayadaha sawirka leh ee tirada badan waa mid cidhiidhi ah, iyadoo xulashooyinka ugu muhiimsan ay ku urursan yihiin muraayadaha leh tusmooyinka refractive ee 1.56 iyo 1.60.
Wareejin
A. Sawir-gacmeedka Dusha Sare ee Hal-Lakab leh (Hab-socodka Sawir-gacmeedka Dahaarka Wareega)
Hawshani waxay ku lug leedahay ku buufinta walxaha sawir-qaade ah dahaarka hal dhinac (Dhinaca A) ee muraayadda. Waxaa sidoo kale loo yaqaan "dahaarka buufinta" ama "dahaarka wareegga," farsamo ay si weyn u qaataan noocyada caalamiga ah. Astaamaha muhiimka ah ee habkan waa midabkeeda saldhigga aadka u fudud - oo si dhow ugu eg saameyn "midab aan sal lahayn" - taasoo keentay muuqaal qurux badan.
Faa'iidooyinka
Waxay suurtogelinaysaa isbeddel midab oo degdeg ah oo isku mid ah.
Qasaarooyinka
Saamaynta sawir-qaadista waxay leedahay muddo gaaban, gaar ahaan heerkulka sare, halkaas oo muraayaddu xitaa lumin karto awooddeeda ay ku beddeli karto midabka gebi ahaanba. Tusaale ahaan, tijaabinta muraayadda biyo kulul: heerkul aad u sarreeya ayaa sababi kara cillad joogto ah oo ku timaadda shaqada sawir-qaadista, taasoo ka dhigaysa muraayadda mid aan la isticmaali karin.
B. Sawir-qaadis Dusha Sare ee Laba-Lakab leh
Hawshani waxay ku lug leedahay in muraayadda lagu dhex geliyo xal sawir-qaade ah, taasoo u oggolaanaysa lakabka sawir-qaade inay ku samaysmaan dahaarka gudaha iyo dibadda ee muraayadda. Waxay hubinaysaa isbeddel midab oo isku mid ah oo ku yimaada dusha sare ee muraayadda.
Faa'iidooyinka
Waxay keentaa isbeddel midab oo degdeg ah oo isku mid ah.
Qasaarooyinka
Ku dhegid liidata oo lakabka sawirka-kormariska ah ku dheggan dusha sare ee muraayadda (dahaarka ayaa u nugul inuu diirmo ama uu duugoobo waqti ka dib).
Faa'iidooyinka Muhiimka ah ee Muraayadaha Sawirka-sawirka ee Dusha Sare (SPIN)
Ma jiraan wax xaddidaad ah oo ku saabsan Adeegsiga Ballaaran
Muraayadaha sawirka-kormeerka dusha sare kuma koobna walxaha ama noocyada muraayadaha. Hadday yihiin muraayadaha caadiga ah ee aspheric, muraayadaha horumarka leh, muraayadaha buluugga ah ee xanniba iftiinka, ama muraayadaha leh tilmaamayaasha iftiinka-celiya oo u dhexeeya 1.499, 1.56, 1.61, 1.67 ilaa 1.74, dhammaantood waxaa loo farsamayn karaa noocyada sawirka-kormeerka dusha sare. Kala duwanaanshaha badeecadan ballaaran wuxuu macaamiisha siiyaa xulashooyin ballaaran.
Midab Dheeraad ah oo loogu talagalay Muraayadaha Awoodda Sare leh
Marka la barbardhigo muraayadaha caadiga ah ee sawir-qaadista tirada badan (MASS), muraayadaha dusha sare ee sawir-qaadista waxay sii wadaan isbeddel midab oo isku mid ah marka la mariyo muraayadaha awoodda sare leh - si wax ku ool ah wax uga qabashada arrinta kala duwanaanshaha midabka ee inta badan ka dhacda alaabada sawir-qaadista tirada badan ee diopter-ka.
Horumarka Muraayadaha Sawirka-MASS (MASS)
Iyada oo la adeegsanayo horumarka degdegga ah ee tignoolajiyada, muraayadaha casriga ah ee sawir-qaadista tirada badan hadda waxay la mid yihiin kuwa dusha sare ee sawir-qaadista marka loo eego xawaaraha midabka beddelaya iyo xawaaraha libdhaya. Muraayadaha awoodda hoose ilaa dhexe, waxay keenaan isbeddel midab oo isku mid ah iyo tayo heer sare ah, iyagoo sii wata faa'iidada ay u leeyihiin saamaynta sawir-qaadista muddada dheer.
