Cataract is a clouding or an opacity of the natural lens inside your eye that can impair the vision.
Over time, cataracts can make your vision blurry, hazy, or less colorful. You may have trouble reading or doing other everyday activities. You might not have any symptoms at first, when cataracts are mild. But as cataracts grow, they can cause changes in your vision.

You may have some problems in your daily life, such as difficulty while driving car at mesopic conditions, sometimes seeing double vision and too much bright lights or having halos around the lights. When your cataract begins to affect your quality of life, you should get an examination appointment from an eye clinic.

After cataract surgery, you won’t need to stay in a hospital after the operation. The procedure takes less than an hour. Most patients are awake during the procedure and need only local anesthesia in order to numb the area around the eye. Intraocular lens implantation is an efficient treatment and really creates big difference in people’s life.
