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.
Signs and symptoms of cataracts include: Clouded, blurred or dim vision. Increasing difficulty with vision at night. Sensitivity to light and glare. Need for brighter light for reading and other activities. Seeing halos around lights. Frequent changes in eyeglass or contact lens prescription.
