What is 20/20 Vision?
This term actually refers to only one aspect of having the perfect vision, which is clarity. When they say “20/20 vision,” it basically tells us that within 20 feet, we see things as they should be seen at that distance.
For example, if you see a car very clearly at 20 feet, without any prescription glasses, medications, or prior eye surgery, then that means you have a 20/20 vision. Consequently, if you have a 20/50 vision, then that means that at 20 meters, you can see things as clear as normal people will see it at 50 feet.
There’s also a chance for people to have a 20/15 eyesight, which means that they can see things at 20 feet clearer than a normal person. The misconception however is that 20/20 vision means you have perfect eyesight.
Again, it only refers to one aspect of our vision. There are still more things to consider like one’s color vision, peripheral vision, and focus vision, among others. So basically, 20/20 vision isn’t the only thing that we should look out for if we are trying to aim or even get close to that perfect vision.
Why Does My Left Eye Grade Differ from the Right?
Another question that might pop into our head when asking “What is 20/20 vision?” is why do our eyes have varying grades from each other. There are cases where some people have a higher/lower eye grade from one eye over the other.
