Which of the following is NOT a typical symptom of cataracts?

The correct answer, which identifies a symptom that is not typically associated with cataracts, is the loss of peripheral vision. Cataracts primarily affect the clarity of the lens in the eye, causing symptoms such as blurred vision, increased glare sensitivity, and, in some cases, double vision.

Blurred vision occurs as the clouding of the lens interferes with the passage of light, leading to a decrease in visual sharpness. Increased glare sensitivity is also common since cataracts scatter light, making it difficult for individuals to see clearly in bright or poorly lit environments. Double vision can arise when cataracts distort the light entering the eye; this can disrupt the brain's ability to merge images from both eyes, leading to the perception of two images.

In contrast, loss of peripheral vision is more characteristic of other eye conditions, such as glaucoma or retinal diseases, rather than cataracts. Cataracts mainly affect central vision instead, highlighting why the loss of peripheral vision is not a typical symptom associated with this condition.
