Dhakhtarku wuxuu qori doonaa warqad dhakhtar u qoray muraayadaha leh dhammaan sifooyinka alaabta.

Marka lagu daro tirada diopters, waxaa muhiim ah in la tixgeliyo radius of curvature of lenses contact. Waa lagama maarmaan in marka la xidho, muraayadda si buuxda u soo celiso qaabka cornea, haddii kale waxay u dhaqaaqi doontaa ama ku cadaadi kartaa unugyada.
