Which condition is defined by inability to distinguish between colors?

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

Answer: (C)

Difficulty distinguishing colors is a hallmark of color vision deficiency. This condition arises when the cone cells in the retina, which detect red, green, and blue light, don’t function normally. The most common form is red-green color vision deficiency, where reds and greens look similar, making it hard to tell those colors apart. This explains why the statement “inability to distinguish between colors” points to color blindness as the correct answer. Visual impairment refers to reduced vision acuity or field, not specifically color discrimination. Strabismus is a misalignment of the eyes that can cause double vision or suppression but doesn’t inherently alter color perception. Partial blindness describes a limited extent of vision, again not about color discrimination.
