What are the symptoms of cataracts?

Cataracts primarily cause a dimming or blurring of vision, which is why the first option is the correct answer. As the lens of the eye becomes clouded due to the buildup of proteins, light is obstructed from passing through clearly, leading to visual impairment. This symptom progresses gradually, often leading individuals to notice that colors appear less vibrant and that bright lights may cause more glare.

Frequent headaches and severe eye pain, while they may occur with various eye conditions, are not typical symptoms of cataracts. Headaches could stem from eye strain or other issues, and severe eye pain usually indicates a more acute condition, such as glaucoma or an eye injury. Therefore, these symptoms are not characteristic of cataracts, making them less relevant concerning this question.
