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.
A cataract should not be removed simply because it is present. Many people have cataracts that do not cause blurred vision, interfere with activities of daily living, or otherwise prevent them from leading active and productive lives. In such cases, these individuals should not undergo unnecessary surgery to remove their cataracts.
