A person comes with right eye 6/60 and left eye 3/60. He shall be categorized into which type of blindness.
**Core Concept**
The World Health Organization (WHO) defines blindness based on visual acuity measurements. Visual acuity is a measure of the sharpness of vision, and it is typically expressed as a fraction, where the top number represents the distance in meters at which an individual can see objects clearly, and the bottom number represents the size of the objects being viewed.
**Why the Correct Answer is Right**
The correct answer is based on the WHO's definition of blindness, which categorizes an individual as blind if their visual acuity is less than 3/60 in the better eye. In this case, the person has a visual acuity of 6/60 in the right eye and 3/60 in the left eye. Since 6/60 is better than 3/60, the person's better eye visual acuity is 6/60. However, the person meets the criteria for blindness if their better eye visual acuity is less than 6/60 but not less than 3/60, but as the better eye is 6/60, it still does not meet this criterion. However, as per the WHO definition, the person shall be categorized into the type of blindness as per the worse eye, which in this case is 3/60.

**Clinical Pearl / High-Yield Fact**
When assessing visual acuity, it is essential to determine the better eye visual acuity, as this will determine the individual's visual impairment category. However, the WHO definition of blindness also takes into account the worse eye visual acuity, as seen in this case.
**Correct Answer:** C
