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.
Not all cataracts impair vision or affect daily living. For those that do, common symptoms include: Cloudy, fuzzy, foggy, or filmy vision. Glare from lamps or the sun, which may be severe. Difficulty driving at night due to glare from headlights. Frequent changes in eyeglass prescription. Double vision.
