that means that you have perfect vision
__________________________________________________________
The numerator refers to within what distance of certain objects you have to be to distinguish them. The denominator refers to within what distance of certain objects a "normal" person has to be to distinguish them. Therefore, 25/25 vision is much like 20/20 vision in that it indicates normal/perfect vision. If the numerator is greater than the denominator (20/15), one's vision is better than normal. If the denominator is greater than the denominator (20/40), one's vision is worse than normal.

Is 20 25 vision good?
Yes, 20/25 vision is considered good and indicates that you can see at 20 feet what a person with normal vision can see at 25 feet. While it is not perfect vision (which is 20/20), many people with 20/25 vision can perform daily activities without significant issues. However, some may require corrective lenses for tasks requiring sharper vision, such as reading or driving at night.
