Damage to which region can cause visual impairments even if the eyes are functioning normally?

Damage to which region can cause visual impairments even if the eyes are functioning normally?

• A. Frontal Lobe
• B. Parietal Lobe
• C. Occipital Lobe
• D. Temporal Lobe

Answer: (C)

Visual information is processed in the occipital lobe, which houses the primary visual cortex. If the eyes are functioning but this brain area is damaged, the brain can’t interpret or receive visual signals properly, leading to visual impairments such as cortical blindness or visual field deficits. The other lobes don’t directly create or interpret visual input: the frontal lobe is more about planning and movement, the parietal lobe handles spatial processing and attention, and the temporal lobe deals with object recognition and memory. So damage to the occipital lobe uniquely disrupts vision despite healthy eyes.
