When your eye doctor tells you that you have cataracts, you might not need surgery right away. It depends on how quickly your cataracts progress and how much they interfere with your life. The only way to improve your vision when you have cataracts is with surgery. Glasses won't help because the lenses of your eyes become cloudy and glasses won't make the cloudiness go away. Fortunately, the cataract procedure is a fairly quick and safe surgery to undergo and it can restore your sight.
