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 often affect both eyes, but rarely equally. People with cataracts may have the following symptoms: Blurry, cloudy, or misty vision. Vision may be affected by small spots or dots. The patient sees small patches that blur parts of the field of vision. Vision worsens when lights are dim.
