20/50 vision is considered bad vision.
Understanding Visual Acuity
Vision is typically measured using a Snellen chart. The measurement is expressed as a fraction, like 20/20, 20/40, or 20/50. The first number (20) represents the distance in feet at which the test is conducted. The second number indicates the distance at which a person with normal vision can see the same thing.
What Does 20/50 Vision Mean?
According to the provided reference, having 20/50 vision means that "if you have 20/50 vision, that means you have much worse than normal vision." More specifically, "if you are standing at 20 feet with 20/50 vision, then what you see is what an average person would see standing 50 feet from the poster." In other words, you need to be much closer to see an object clearly compared to someone with normal vision.
Comparison Table:
| Vision Measurement | Interpretation |
|---|---|
| 20/20 | Normal vision. You can see clearly at 20 feet what an average person can see at 20 feet. |
| 20/40 | Worse than normal vision. You need to be at 20 feet to see what a person with normal vision can see at 40 feet. |
| 20/50 | Worse than normal vision. You need to be at 20 feet to see what a person with normal vision can see at 50 feet. |
Therefore, a higher second number indicates poorer vision.
