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.
A cataract is a clouding of the lens of the eye. Cataracts are extremely common, and most cataracts are a result of the aging process. Although many cataracts are not significant enough to require treatment, surgical removal of cataracts is usually safe and effective, resulting in improvement of vision.
