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 usually effect vision, but sometimes the symptoms are not immediately appearant. A cataract can cause cloudy, blurry or double vision. They may fade colors or cause a glare around light sources. Cataracts can also cause poor night vision and frequent changes in optical prescriptions.
