Tilmaamaha Alaabta
1. Sidee bay u shaqeeyaan muraayadaha aragga keliya?
Lens-ka-aragga keliya waxa loola jeedaa muraayadda aan astigmatism-ka lahayn, taas oo ah muraayadda ugu caansan.Guud ahaan waxa ay ka samaysan tahay dhalo ama resin iyo agabka kale ee indhaha.Waa walxo hufan oo leh hal ama in ka badan oo sagxado ah.Lens-ka monoptic waxaa loo tixraacaa hal lens oo keliya, taas oo ah, lens leh hal xarun indho-indho oo kaliya, kaas oo saxa aragtida dhexe, laakiin ma saxo aragtida durugsan.
2. Waa maxay faraqa u dhexeeya hal lens iyo lens-bifocal?
Lens-ka caadiga ah ee hal-aragga, marka sawirka dhexe ee lensku uu ku dhaco aagga dhexe ee macular ee retina, diiradda sawirka xuubka xuubka ayaa dhab ahaantii ku dhacaya dhabarka dhabarka, taas oo ah waxa loogu yeero. fogaan-aragtida durugsan.Natiijo ahaan dhibicda focal waxay ku dhacdaa dhabarka retina, waxay keeni kartaa dhererka jinsiga magdhowga ah ee dhidibka isha si, iyo dhidibka isha ee koritaanka kasta 1mm, lambarka myopia lambarka wuxuu kori karaa 300 darajo.

3. Waa maxay faraqa u dhexeeya HC, HMC iyo SHC?
