Tilmaamaha Alaabta
Muraayadaha kala duwani waxay ka kooban yihiin shaandheyn dahaaran oo u oggolaanaysa iftiinka tooska ah inuu dhex maro laakiin xanniba iftiinka toosan, ciribtirka iftiinka.Waxay indhaheenna ka ilaaliyaan iftiinka waxyeellada leh ee laga yaabo inuu indho-tiro.Waxaa jira faa'iidooyin iyo faa'iido darrooyin lenses-ka-soo-baxa, sida soo socota:
1. Faa'iidooyinka:
Muraayadaha kala duwani waxay yareeyaan iftiinka iftiinka hareerahayaga, hadday si toos ah uga imanayaan qorraxda, biyaha ama xitaa barafka.Indhahayagu waxay u baahan yihiin ilaalin marka aan waqti ku qaadaneyno dibadda.Caadi ahaan, muraayadaha muraayadaha indhaha ayaa sidoo kale ku dhisi doona ilaalinta UV taas oo aad muhiim ugu ah lammaanaha muraayadaha.Iftiinka ultraviolet wuxuu dhaawac u geysan karaa araggayaga haddii aan si joogto ah ula kulanno.Shucaaca cadceedda ka soo baxaa waxa uu sababi karaa dhaawacyo is biirsaday oo jidhka ah kuwaas oo aakhirka u horseedi kara hoos u dhaca aragga dadka qaarkood.Haddii aan rabno in aan la kulanno horumarka ugu sarreeya ee suurtagalka ah ee aragtideena, ka fiirso lenses polarized kuwaas oo waliba ka kooban sifo nuugaya fallaadhaha HEV.
Faa'iidada ugu horreysa ee lenses-ka muraayadaha ah waa inay bixiyaan aragti cad.Muraayadaha waxaa loo dhisay si ay u shaandheeyaan iftiin dhalaalaya.Iftiinka la'aanteed, waxaan awood u yeelan doonnaa inaan aragno wax badan oo cad.Intaa waxaa dheer, muraayadaha ayaa hagaajin doona isbarbardhigga iyo caddaynta muuqaalka.
Faa'iidada kale ee lenses-ku-salaysan ayaa ah inay hoos u dhigi doonaan cadaadiska isha inta aan ka shaqeyneyno dibadda.Sidii hore loo sheegay, waxay yareeynayaan dhaldhalaalka iyo milicsiga.
Ugu dambeyntii, muraayadaha muraayadaha indhaha ayaa u oggolaanaya aragtida dhabta ah ee midabada laga yaabo inaynaan ku helin muraayadaha muraayadaha caadiga ah.
2. Khasaarooyin:

Marka aan xidhno muraayadaha muraayadaha indhaha, way adkaan kartaa in aan eegno muraayadaha LCD.Haddii tani ay tahay qayb ka mid ah shaqadayada, muraayadaha muraayadaha ayaa loo baahan doonaa in la saaro.

Saddex, haddii aan u nugulnahay iftiinka marka uu isbeddelo, muraayadahani waxaa laga yaabaa inaanay nagu habboonayn.Muraayadaha muraayadaha muraayadaha ah waxay u beddelaan iftiinka si ka duwan muraayadaha muraayadaha qorraxda ee caadiga ah.
3. Waa maxay faraqa u dhexeeya HC, HMC iyo SHC?
