Macular degeneration primarily affects which aspect of vision?

Macular degeneration primarily affects central vision, which can lead to blurriness in the center field of vision. This condition primarily impacts the macula, the central part of the retina that is crucial for sharp, clear vision and for tasks such as reading and recognizing faces. When the macula deteriorates, it hinders the ability to see fine details directly in the line of sight, leading to a central blind spot or blurriness where clear vision is normally expected.

In contrast, peripheral vision remains relatively intact, which distinguishes macular degeneration from other types of vision loss. Night vision and color perception can also be affected by different eye conditions, but these are not the primary issues associated with macular degeneration. The hallmark symptom is indeed the blurriness or distortion of vision in the center field, making the selected answer clearly the most accurate representation of how macular degeneration impacts vision.
