Which of the following is a common symptom of AMD?

Central vision loss is a hallmark symptom of age-related macular degeneration (AMD). As AMD progresses, it affects the macula, the part of the retina responsible for sharp, central vision. This manifests as a gradual blurring or darkening of central vision, making it difficult for individuals to read, recognize faces, or perform tasks that require fine visual detail.

The other symptoms mentioned are more associated with different types of eye conditions. For instance, loss of peripheral vision is typically related to glaucoma or retinal conditions, difficulty seeing in low light can be a symptom of cataracts or retinitis pigmentosa, and night blindness is primarily linked to conditions affecting rod photoreceptors in the retina. Therefore, central vision loss distinctly characterizes AMD, making it the correct answer in the context of common symptoms associated with this condition.
