You may not notice a slight change in your vision, as cataract starts out very tiny, but as it grows from the size of a pin head, you may notice that your vision is becoming blurry, and you may feel you are looking through dirty lenses. Object edges may appear to fade into one another and colors may not appear as bright as they should. The most common symptoms of a cataract are: » Cloudy or blurry vision. » Problems with light, headlights that seem too bright, glare from lamps or very bright sunlight. » Colors that seem faded. » Poor night vision. » Double or multiple vision. » Frequent changes in glasses or contact lenses. » Optical aids such as eyeglasses or contact lenses are no longer effective.
