Achromatopsia is characterized by which of the following?

• A. Improved Color Vision in Daylight.
• B. Only Peripheral Vision Loss Without Any Other Symptoms.
• C. Absence of Color Vision. Decreased Vision. Nystagmus. Photophobia.
• D. Increased Color Perception With High Acuity.

Answer: (C)

Achromatopsia is a condition where color vision is absent or greatly reduced due to cone dysfunction. The typical signs include no or very limited color perception, decreased visual acuity, nystagmus (involuntary eye movements), and photophobia (sensitivity to light). This combination is characteristic and explains why the description of absence of color vision with decreased vision, nystagmus, and light sensitivity best matches the condition. The other options describe scenarios that contradict these core features, such as improved color vision or vision loss without the specific color blindness and light sensitivity that accompany achromatopsia.
