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.
Cloudy vision, foggy vision - that's how people describe cataracts. A cataract is a clouding of the eye's lens that happens so gradually you may not really notice it until you have trouble driving at night or difficulty reading. At that point, you may need cataract surgery - a standard procedure that is very effective.
