    Waa maxay tusmada sare ee 1.74 lenses?

    Haddii aad haysato warqad dhakhtar aad u xoog badan, waa inaad tixgelisaa 1.74 lenses Ultra Thin High Index.

    Index lenses 1.74 sare ayaa ah muraayadaha ugu khafiifsan, ugu fidsan, uguna quruxda badan ee abid la sameeyay.

    Muraayadahan aadka u dhuuban waxay ku dhow yihiin 40% ka khafiifsan balaastiig iyo 10% ka khafiifsan 1.67 muraayadaha tusmooyinka sare, kuwaas oo ku siinaya ugu dambayn tignoolajiyada iyo waxyaalaha la isku qurxiyo. Lens-ka khafiifka ah ayaa aad u sasabasan, isaga oo yareynaya qallooca ka imaan kara warqadaha daawada marka lagu sameeyo lenses tayo hoose leh.

    Waa maxay dhumucda muraayada aan dooranayaa?

    Haddii aad dhexdhexaad tahay, ama aad aragti gaaban tahay waxaad ka faa'iidaysan doontaa muraayadaha khafiifka ah maadaama dhumucda cidhifka muraayadahaagu ay noqon doonaan kuwo muuqda.

    Muraayadaha leh index refractive 1.6 ayaa ku habboon daawoyinka laguu qoray halka qiimaha daawada SPH uu u dhexeeyo -2.50 iyo -4.00.

    Inta u dhaxaysa -4.00 iyo -6.00 waxa aanu ku talinaynaa lens leh index refractive of 1.67, iyo warqad kasta oo ka mid ah muraayadda leh index refractive 1.74 ayaa noqon doona mid ku habboon.

    Haddii dawadaadu ay dhaafto -5.00 waxaan u baahan doonaa cabbir sax ah ee masaafada u dhaxaysa ardaydaada, oo inta badan loo yaqaan PD.

    Sababtoo ah muraayadaha indhaha ee dheer iyo aragtida gaaban way kala duwan yihiin, waxaa jira tixgelin kala duwan mid kasta.
