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.
Most people with cataracts have a cataract in both eyes. However, one eye may be worse than the other because each cataract develops at a different rate. Some people with cataract don't even know it. Their cataract may be small, or the changes in their vision may not bother them very much.
