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.
Cataract is a clouding of the lens, causing blurry or color-tinted vision. People with cataracts often report âhaloesâ surrounding objects that they are looking at, particularly at night. It is most common in older people, and cataracts can be removed by surgery that replaces the lens with an artificial lens.
