Caadiyan, muraayaduhu waxay leeyihiin walxahan soo socda:
1. Lenska xabagta walxaha lenska: Resin waa walax kiimiko oo leh qaab dhismeedka phenolic. Astaamaha: miisaanka fudud, iska caabinta heerkulka sare, iska caabin xoog leh, oo si wax ku ool ah u xannibi kara fallaadhaha ultraviolet.
2. Nylon lens Lens Qalabka: oo laga sameeyay naylon, muuqaalada: dabacsanaan aad u sarreeya, tayada indhaha ee aad u fiican, iska caabin xoog leh, oo badanaa loo isticmaalo sida walxaha ilaalinta.
3. Lenska polyester-ka ee kaarboonka leh (lens PC) muraayadaha muraayadaha: xoog leh, aan sahlanayn in la jebiyo, saameyn u adkaysta, walxaha muraayadaha gaarka ah ee loogu talagalay muraayadaha isboortiga, qiimaha ayaa ka sarreeya muraayadaha akril.
4. Lens-ka lenska (ACrylic lens): Waxa uu leeyahay adayg aad u fiican, miisaan fudud, aragti sare iyo ka-hortagga ceeryaamo wanaagsan.
Hordhac Wax-soo-saar
Dhakhaatiirta indhaha waxay ku talinayaan inaad had iyo jeer xidhato muraayadaha indhaha si aad u ilaaliso indhahaaga; sababtoo ah kubaddeenu (lens) waa mid aad u fudud in la nuugo fallaadhaha ultraviolet, waxyeelada fallaadhaha ultraviolet waxay leedahay laba sifo oo caan ah:
1. Waxyeelada fallaadhaha ultraviolet ayaa urursan doona. Maadaama iftiinka ultraviolet uu yahay iftiin aan la arki karin, way ku adag tahay dadka inay si macquul ah u fahmaan.
2.Dhibaatooyinka fallaadhaha ultraviolet ee indhaha waa kuwo aan dib loo celin karin, taas oo ah, aan laga soo kaban karin. Sida: Qalliinka indhaha indhaha waxaa lagu beddeli karaa oo keliya muraayadaha indhaha. Dhaawaca muddada dheer ee isha wuxuu si fudud u horseedi karaa dhaawac soo gaadho isha-koriyaha iyo isha, oo daruurta muraayadda ilaa uu ka dhaco caadka, taasoo keenta dhaawac muuqda oo joogto ah.
Maadaama waxyeelada fallaaraha ultraviolet ee indhaha aan la arki karin, isla markiiba lama dareemi karo. Haddii aadan xiran muraayadaha, ma dareemaysid raaxo gaar ah. Waxa kaliya oo ay la macno tahay in indhahaagu aanay aad ugu nugulayn iftiinka muuqda (sida dhaldhalaalka, dhaldhalaalka, iyo iftiinka iftiimaya). , oo kama ilaalin karo waxyeelada UV.
Miyay mugdi sii jiraan muraayadaha qorraxda, ayaa ka sii wanagsan saamaynta xannibista UV?
Maya, shaqada muraayadda si ay u xannibto fallaadhaha ultraviolet waa in lagu daaweeyaa hab gaar ah (ku dar budada UV) inta lagu jiro habka wax soo saarka, si ay muraayaddu u nuugi karto iftiinka waxyeellada leh ee ka hooseeya 400NM sida ultraviolet rays marka iftiinku galo. Waxba kuma laha qoto dheeraanta filimka.
