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.
This is especially true if your cataracts are causing problems with your driving vision and are increasing your risk of an accident. 1  Signs and symptoms of vision problems caused by cataracts include: 2  Blurred vision. 3  Poor night vision. 4  Colors appearing less vivid or washed out. 5  Glare and halos around lights at night.
