Understanding Cataracts: Causes, Symptoms, and Diagnosis Cataracts are a common eye condition that affects millions of people worldwide.

The eye’s lens is a clear structure that focuses light onto the retina, sending visual signals to the brain. A cataract is a clouding of this lens, which can cause vision problems. The lens is composed of water and proteins arranged in a specific way to keep the lens clear and allow light to pass through. However, as we age, the proteins in the lens may clump together and form a cataract.Cataracts can also develop in children and young adults due to genetic factors, trauma to the eye, or medical conditions such as diabetes.
