A normal eyesight score is typically represented by 20/20 vision. This means you can see clearly at a distance of 20 feet what a person with normal vision can see at 20 feet.
However, it's important to understand that "normal" eyesight can vary slightly from person to person. While 20/20 is considered the standard, many people have slightly better or worse vision and still have healthy eyes.
Understanding Eyesight Scores
Eyesight scores are measured using a Snellen eye chart. This chart contains letters of different sizes, and you are asked to read them from a specific distance. The score is expressed as a fraction, where the first number represents the distance you are standing from the chart, and the second number represents the distance at which a person with normal vision could read the same line.
Here are some examples:
- 20/20: You can see clearly at 20 feet what a person with normal vision can see at 20 feet.
- 20/40: You can see clearly at 20 feet what a person with normal vision can see at 40 feet. This means your vision is slightly worse than normal.
- 20/15: You can see clearly at 20 feet what a person with normal vision can see at 15 feet. This means your vision is slightly better than normal.
What to do if your eyesight isn’t 20/20
If your eyesight isn’t 20/20, it doesn’t necessarily mean you have a problem. However, it’s important to get your eyes checked regularly by an eye doctor. They can determine if your vision needs correction and recommend the best treatment options, such as eyeglasses or contact lenses.
