20 20 vision means that you can see clearly at 20 feet what an average person can see clearly at 20 feet. If you have 20 20 vision, it doesn’t mean you have perfect vision. It just means your vision is considered normal or average.
Some people think that having 20 20 vision means they can see perfectly, but that’s not always the case. Having 20 20 vision just means you have average vision. People with perfect vision typically have 20 10 vision, which means they can see clearly at 20 feet what an average person can see clearly at 10 feet.
While having 20 20 vision is considered to be normal, it’s still possible to have vision problems even if your vision is considered to be average.
Some common vision problems include:
- Astigmatism – This is a condition where the eye isn’t perfectly round, which can cause blurry or distorted vision.
- Farsightedness – This is a condition where you can see far away objects clearly, but objects up close are blurry.
- Nearsightedness – This is a condition where you can see objects up close clearly, but far away objects are blurry.
If you have any of these vision problems, you may need to wear glasses or contact lenses in order to see clearly. If you have a more serious vision problem, you may need to see a doctor or an eye specialist.
Vision problems can often be corrected with glasses, contact lenses, or surgery. If you have a vision problem, it’s important to see an eye doctor so that you can get the treatment you need.
