Sida aan wada ognahay, heerka myopia waa mid hooseeya, kala duwanaanshaha lenses ilaa fareemooyinka ayaa ka ballaaran kan myopia sare.Markaa dadka qaba myopia sare, noocee ah muraayadaha ayaa ah kuwa ugu habboon iyaga?Maanta, raac tifaftiraha, aynu wada fuulno.
1.Maxay rabaan dadka maan-yaqaanka ah?
Khasaaraha ugu weyn ee myopia sare waa in kororka awoodda, uu sii dhumuc weyn yahay muraayadda.Sidaa darteed, qof kastaa wuxuu rabaa in lensku noqdo mid khafiif ah oo dhuuban marka la ururinayo muraayadda awoodda sare leh.
Si kastaba ha ahaatee, shahaado kasta waxay leedahay dhumuc, iyo index refractive korodhay waxay yaraynaysaa dhumucda ku salaysan dhumucda muraayadda lafteeda.Xataa muraayadda 1.74, waa in ay ka dhumucdo heerka hoose.
2.Sidee loo doortaa muraayadaha indhaha ee sare?
Waxaan aaminsanahay in qof kastaa og yahay in bartamaha lensku uu dhumuc weyn yahay, dhinacyaduna ay khafiif yihiin.Markaa haddii aad rabto muraayad khafiif ah, waxaad dooran kartaa muraayad 1.74 ah.Tani dhab ahaantii dhib maaha.Maxaa kale oo aad sameyn kartaa si aad u gaarto natiijooyin wanaagsan?Tifaftiruhu waxa uu qof walba u soo koobay dhawr hab, saaxiibaduna way isku dayi karaan marka ay ururinayaan muraayadaha.
(a) Haddii aad dooratid fareemka acetate, dhumucda uu jirku xannibi karo ayaa noqon doona mid dhumuc weyn leh oo u muuqan doona mid khafiif ah, iyo qaabka acetate ma cadaadin doono buundada sankaaga sababtoo ah muraayadaha ayaa aad u culus.
(b) Doorashada qaab yar ayaa ka caawin doonta muraayadaha guud inay u muuqdaan kuwo khafiif ah, sababtoo ah muraayadaha ayaa dhuuban dhexda waxayna qaro weyn yihiin dhinacyada, markaa doorashada jir yar waxay ka dhigi doontaa muraayadaha kuwo khafiif ah.
(c) Inta lagu jiro habaynta, sayidku wuxuu samayn doonaa gooyn yar oo gees ah si loo yareeyo dhumucda muraayadda.Haddii xagashani aad loo gooyo, goobada cad ayaa laga yaabaa inay kordhiso, saameynta khafiifinta lama gaari doono haddii goyntu yar tahay.Waxaa lagu go'aansan karaa iyadoo loo eegayo doorbidka shakhsi ahaaneed, waxaana suurtagal ah in loo sheego processor-ka.
