What is croup? Croup is a fairly common respiratory condition in children usually caused by a viral infection or allergic reaction. Croup affects the windpipe (trachea), the bronchi (airways to the lungs), and the larynx (voice box).
However, as the cataract continues to become denser, vision also becomes more cloudy, and stronger glasses or contact lenses will no longer improve sight. Cataracts typically develop gradually and are usually not painful or associated with any eye redness or other symptoms unless they become extremely advanced.
cataracts are formed when the clear lens inside your eye becomes cloudy or misty this is a gradual process that usually happens as we get older it does not hurt the early stages of a cataract do not necessarily affect your sight the only proven treatment for a cataract is surgery if the cataract gets to the stage where it affects your sight your optometrist will refer you to hospital to have this done
