Rarely, cataracts can present at birth or in early childhood as a result of hereditary enzyme defects, and severe trauma to the eye, eye surgery, or intraocular inflammation can also cause cataracts to occur earlier in life.
Cataracts often form slowly and cause few symptoms. When symptoms are present, they can include: 1  Vision that is cloudy, blurry, foggy or filmy. 2  Sudden short sightedness. 3  Changes in the way you see colour, especially yellow. 4  Problems driving at night because oncoming headlights are distracting. 5  Problems with glare. 6  Double vision.
