## Core Concept
The VISION 2020 goal, also known as the "Global Initiative for the Elimination of Avoidable Blindness," is a collaborative project between the World Health Organization (WHO) and the International Agency for the Prevention of Blindness (IAPB). It aims to eliminate avoidable blindness by the year 2020. The main diseases targeted under this initiative include cataract, refractive errors, low vision, diabetic retinopathy, and childhood blindness.

## Why the Correct Answer is Right
The diseases given prominence in VISION 2020 include:
- Cataract
- Diabetic retinopathy
- Refractive errors
- Onchocerciasis (river blindness) and trachoma are also major targets.

## Why Each Wrong Option is Incorrect
- **Option A:** If a specific disease or condition is listed among the targets of VISION 2020, it would be considered correct in the context of being given global prominence. Without specifics on A, B, C, and D, we infer based on common knowledge of VISION 2020 targets.
- **Option B:** Similarly, if another condition is a target, it would be incorrect to exclude it.
- **Option C:** This could potentially be a correct target as well, depending on what it specifies.
- **Option D:** Given as the correct answer, implying it is not specifically targeted or emphasized under VISION 2020 compared to the others.

## Clinical Pearl / High-Yield Fact
A key aspect of VISION 2020 is its focus on major causes of blindness that are preventable or treatable. The initiative emphasizes the need for comprehensive eye care services and the importance of partnerships in achieving its goals. A memorable point is that VISION 2020 focuses on diseases like cataract, diabetic retinopathy, and trachoma, which are significant public health concerns.
