Question

light goes through this part of the eye, in which the structure itself can flatten or become cloudy with cataracts;

macula lutae

lens

blind spot

fovae centralis

Explanation:

To solve this, we analyze each option:

• Macula lutea is for central vision, not for light passage with flattening/clouding.
• Lens: Light passes through it, it can flatten (for focusing) and develop cataracts (clouding).
• Blind spot has no photoreceptors, not related to flattening/clouding.
• Fovea centralis is for sharp vision, not for light passage with those changes.

Answer:

B. lens
