Muraayadaha muraayadaha waa muraayado ku dhex jira fareem oo lagu xidho isha horteeda si looga ilaaliyo ujeedooyinka qurxinta.Muraayadaha ayaa sidoo kale loo isticmaali karaa in lagu saxo dhibaatooyinka aragga ee kala duwan, oo ay ku jiraan aragti dhow, aragti fog, astigmatism, presbyopia ama strabismus, amblyopia iyo wixii la mid ah.
Haddaba maxaad ka taqaannaa muraayadaha?Sidee loo doortaa muraayadda ku habboon naftiisa?Aan ku bilowno saddex arrimood:
Xawilaadda muraayadaha: Markasta oo ay sare u kacdo gudbinta, ayaa ka sii fiicnaan doonta caddaynta
Nooca muraayadda:
Beddel lenska midabka: lensiska midabka beddelka ayaa hagaajin kara gudbinta iyada oo lensku beddelo midabka, ka dhigaya isha bini'aadamka la qabsiga isbeddelka deegaanka, yaraynta daalka aragga, ilaalinta isha.
Lens index refractive sare: Mar kasta oo index refractive ah, ayaa khafiif ah lens.
Muraayadaha horumarka leh: La qabso dhammaan xaaladaha iyo masaafada
Muraayadaha muraayadda:
Way ka adkaysi badan tahay muraayadaha kale, laakiin xoogaa culus.
Lenska xabagta polymerka:
Ka fudud muraayadaha muraayadda, iska caabbinta saameyntu ma fududa in la jebiyo, laakiin adkaanta waa yar tahay, fududahay in la xoqo.
Muraayadaha PC:
Magaca kiimikada PC waa polycarbonate, oo leh adayg adag, sidoo kale loo yaqaan "space piece", "universe piece", "lens badbaado", ma fududa in la jebiyo.Waxay miisaankoodu kala badh ka yihiin lenses-dhaqameedka resin-ka, waxaana inta badan loo isticmaalaa muraayadaha aragga gaaban ee carruurta ama maaskaro indhaha ee ciyaartoyda.
Iftiinka buluugga ah:
Daraasaduhu waxay ogaadeen in iftiinka buluuga ah uu u keeni karo dhaawac dabadheeraad ah oo ku yimaada retina, taasoo keenta cillad maskaxeed.Hadda iftiinka buluuga ah wuxuu ku badan yahay ilaha iftiinka macmalka ah.Lensiska buluuga ah ee lidka ku ah wuxuu ilaalin karaa indhaha, wuxuuna yarayn karaa waxyeelada ay keenaan kumbuyuutarka iyo isha iftiinka LED-ka.
Polarization:
Astaamaha iftiinka kala-soocida guud ahaan waa in la baabi'iyo iftiinka muuqda iyo iftiinka kala firdhisan, xanniba iftiinka xoogga leh, go'doominta iftiinka ultraviolet ee waxyeellada leh, saameynta muuqaalku waa caddahay, caabbinta saameynta, caabbinta xoqan.
Dahaarka muraayadaha:
Waxay yarayn kartaa iftiinka muraayadda ee dusha muraayadda, waxay ka dhigi kartaa shayga, yaraynta iftiinka muraayadda, kordhinta gudbinta iftiinka.
