Soo ogow Sababaha Aragtida 20/40

Cabbiraad ah Aragtida 20/40 waxay u dhici kartaa sababo kala duwan awgood, waanan fahamsanahay sida ay tani u noqon karto mid walaac leh. Badanaa, waxaa sabab u ah khaladaadka soo noqnoqda jeclow miyir-beelid (aragtida fog) iyo hyperopia (aragtida fog). Xaaladahan waxay dhacaan marka qaabka isha uu ka hortago in iftiinku si toos ah ugu fiirsado retina, taasoo keenta aragti aan caddayn.

Tusaale ahaan, ku dhawaad 900,000 oo Mareykan ah ayaa wajahaya caqabado sida retinopathy, taas oo sidoo kale gacan ka geysan karta aragtida oo daciifisa waxayna keeni kartaa aragti 20/40. Waa wax caadi ah in laga walwalo isbeddellada la xiriira da'da, gaar ahaan presbyopia, kaas oo caadi ahaan bilaabma qiyaastii da'da 40 wuxuuna saameeyaa awoodda diiradda saarista walxaha dhow, taasoo sii adkeyneysa caddeynta.

Cataracts, oo lagu garto daruuraha muraayadda indhaha, waa sabab kale oo soo noqnoqda oo keenta aragga oo yaraada, taasoo saameysa hawlaha maalinlaha ah. Intaa waxaa dheer, dhaawacyada indhaha ama cudurrada waxay keeni karaan hoos u dhac ku yimaada aragtida. Fahmidda arrimahan ayaa muhiim u ah aqoonsashada saxda ah. xulashooyinka sixitaanka. Dad badan ayaa si guul leh u hagaajiyay aragtidooda laga bilaabo 20/40 ilaa 20/15 iyada oo loo marayo tallaabooyin diiradda la saarayo. Tusaale ahaan, hal bukaan ayaa aragtidiisa ka wanaajiyey 20/40 ilaa 20/15 saddex bilood gudahood iyagoo raacaya tallaabooyin sixitaan oo gaar ah.

Northwest Eye, khabiiradayadu waxay xoogga saarayaan muhiimadda joogtada ah ee isticmaalka joogtada ah baaritaannada indhaha si loola socdo xaaladahan. Waxay soo jeedin karaan ikhtiyaarro sixitaan, sida muraayadaha indhaha ama muraayadaha indhaha, si loo hagaajiyo caddeynta aragga loona wanaajiyo tayada guud ee noloshaada.

Waxaa sidoo kale muhiim ah in la ogaado in gobollo badan oo Mareykanka ah ay u baahan yihiin heerka ugu yar ee aragga, gaar ahaan 20/40 aragga, si loo helo liisan darawalnimo oo aan xadidnayn, taasoo muujinaysa saameynta dhabta ah ee heerkan muuqaalka fiiqan.

Waxaan halkaan u joognaa inaan kaa caawinno habkan.

Baadh Ikhtiyaarada Sixitaanka ee Aragtida 20/40

Haddii aad la kulanto Aragtida 20/40, waxaa laga yaabaa inaad la yaaban tahay fursadahaaga sixitaanka. Waan fahamsanahay in tani ay noqon karto waayo-aragnimo adag, waana muhiim inaad ogaato in ay jiraan dhowr waddo oo aad mari karto, mid walbana uu leeyahay faa'iidooyin u gaar ah.

LASIK waxay dib u qaabeysaa cornea si ay u xoojiso diiradda, halka qalliinka cataract-ka uu muraayadda daruurta ah ku beddelo mid macmal ah, taasoo inta badan dib u soo celineysa aragtida 20/20 ama xitaa ka sii wanaagsan. Heerka guusha ee LASIK waa mid cajiib ah, iyadoo in ka badan 99% oo bukaan ah ay gaarayaan aragti 20/40 ama ka wanaagsan. Bukaanno badan ayaa muujinaya qanacsanaanta natiijooyinkooda, taas oo runtii ah mid dhiirigelin leh.

Ka fiirso sheekooyinka shakhsiyaadka sida Thomas, oo ka gudbay muraayadaha indhaha una gudbay aragti fiiqan ka dib markii uu horumar weyn ka sameeyay muuqaalka indhaha, iyo Judith, oo dib u heshay caddeyn 20/20 ka dib qalliinka cataract. Waayo-aragnimadooda waxay muujinayaan saameynta isbeddelka ah ee hababkani ku yeelan karaan noloshaada.

Northwest Eye, waxaan ku bixinnaa fursado cusub sida Muraayadaha La Hagaajin Karo ee Fudud (LAL), kaas oo ka jawaabaya iftiinka UV-ga isla markaana u oggolaanaya hagaajinta qalliinka ka dib qalliinka oo loogu talagalay qaab nololeedkaaga. Habkan shaqsiyeed ee sixitaanka aragga ayaa hubinaya inaad hesho daryeel ku habboon baahiyahaaga gaarka ah.

Waxa kale oo uu ka hadlayaa saameynta suurtagalka ah ee hawlaha maalinlaha ah. Waxaan xoogga saareynaa muhiimadda baaritaannada joogtada ah ee indhaha waxaana sahamineynaa ikhtiyaarro sixitaan oo kala duwan, laga bilaabo muraayadaha indhaha iyo muraayadaha indhaha ilaa qalliinnada sida LASIK iyo qalliinka cataract. Mid kasta oo ka mid ah xalalkan wuxuu bixiyaa faa'iidooyin gaar ah, taasoo kuu oggolaanaysa inaad si weyn u horumariso tayada noloshaada.
