Which condition would you diagnose when a patient cannot differentiate certain colors?

• A. Partial Blindness
• B. Visual Impairment
• C. Color Blindness
• D. Uveitis

Answer: (C)

Color vision deficiency is the ability to distinguish colors that is altered, leading to difficulty differentiating certain hues. This scenario describes color vision deficiency—often called color blindness—where someone has trouble distinguishing specific colors rather than losing overall sight. It’s most commonly a hereditary red-green type, though blue-yellow forms exist and complete color blindness is rare. This differs from partial blindness or visual impairment, which refer to reduced vision overall, and from uveitis, which is inflammation inside the eye and not specifically about color discrimination. In practice, color vision testing (like Ishihara plates) helps confirm the pattern of color confusion.
