Step-by-step solution for: Near Vision Test Card
It looks like you've uploaded an image of a Near Vision Card, which is typically used to test or assess visual acuity at close distances (usually around 14 inches or 35 cm). This type of card is often used by eye care professionals during eye exams, especially for evaluating near vision, such as reading ability.
Let’s analyze and explain the content of this card:
---
This is a near vision chart designed for testing visual acuity at close range. The text on the card is printed in decreasing sizes to assess how well a person can read small print up close.
---
- Title: "NEAR VISION CARD"
- Top Line: Large letters — DT4
- Subsequent Lines: Smaller lines with letters and numbers:
- L E S 3
- R F X B N
- P O S T A
- Then smaller lines: D O P L M, etc.
- Each line has associated values like 20/20, 20/30, 20/40, etc., which indicate visual acuity.
- At the bottom: Instructions about holding the card at approximately 14 inches (35 cm) from the eyes.
---
The purpose is to determine if a person can clearly see small print at a normal reading distance. It helps diagnose:
- Presbyopia (age-related difficulty focusing on close objects)
- Refractive errors (nearsightedness, farsightedness, astigmatism)
- Visual acuity for reading and close work
---
1. The patient holds the card at about 14 inches (35 cm) from their eyes.
2. They are asked to read the smallest line they can see clearly.
3. The smallest line they can read corresponds to their near visual acuity.
For example:
- If someone can read the line labeled "20/20", it means they have normal near vision.
- If they can only read the "20/40" line, they may need corrective lenses for reading.

Here's a breakdown of what each line likely represents:
| Line | Text | Acuity |
|------|------|--------|
| 1 | DT4 | 20/20 |
| 2 | LES3 | 20/25 |
| 3 | RFXBN | 20/30 |
| 4 | POSTA | 20/40 |
| 5 | DOPLM | 20/50 |
| 6 | STKEM | 20/60 |
| 7 | *** | 20/80 |
Note: The asterisks might be placeholders or represent even smaller characters that are hard to discern.
---
- The larger the number after "20/" (e.g., 20/40), the worse the vision.
- Normal near vision is 20/20.
- Most people over age 40 will require correction to achieve 20/20 near vision due to presbyopia.
---
Since this is a visual acuity test, no mathematical or logical problem-solving is required unless you're analyzing the design or interpreting results based on patient input.
If your task was to read the chart or interpret a result, then:
> Example: If a person reads down to the "POSTA" line (20/40), their near visual acuity is 20/40, indicating they need reading glasses or bifocals.
---
- This is a near vision card used to test reading vision at close range.
- It contains progressively smaller letters and numbers.
- The smallest readable line determines visual acuity.
- Standard reading distance is 14 inches (35 cm).
- Normal near vision is 20/20.

🧠 Purpose of the Test
The purpose is to determine if a person can clearly see small print at a normal reading distance. It helps diagnose:
- Presbyopia (age-related difficulty focusing on close objects)
- Refractive errors (nearsightedness, farsightedness, astigmatism)
- Visual acuity for reading and close work

✔ How It Works
1. The patient holds the card at about 14 inches (35 cm) from their eyes.
2. They are asked to read the smallest line they can see clearly.
3. The smallest line they can read corresponds to their near visual acuity.
For example:
- If someone can read the line labeled "20/20", it means they have normal near vision.
- If they can only read the "20/40" line, they may need corrective lenses for reading.
