Cataract is a condition affecting the eye that causes clouding of the eye lens, stopping light reaching the back of the eye and causing blurred or misty vision.
Cataracts usually develop slowly over many years, so you may not notice symptoms at first. They often develop in both eyes, although each eye may be affected differently. Cataracts are not painful and don’t make your eyes red or irritated. You’ll usually have blurred, cloudy or misty vision, or you may have small spots or patches where your vision is less clear.The most effective treatment for cataracts is surgery. This is usually recommended if your loss of vision is affecting your daily life and activities such as driving or reading. Cataract surgery is a very common procedure and involves taking out the cloudy lens and replacing it with a clear, artificial one.
