What is a cataract?
A. A large waterfall
B. A type of rock formation
C. An eye condition that causes blurry vision
D. A type of tropical storm
Explanation:
A cataract is a common eye condition that can cause blurry vision, faded colors, and difficulty seeing in low light. It occurs when the natural lens of the eye becomes cloudy and opaque, which can interfere with the passage of light and affect the clarity of images that reach the retina. Cataracts are often associated with aging, but they can also be caused by other factors such as injury, disease, or prolonged exposure to UV radiation. While they can be corrected with surgery, cataracts can have a significant impact on daily life and should be treated by a qualified healthcare professional. A large waterfall, a type of rock formation, and a type of tropical storm are not related to cataracts.
