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.
It means that a person needs to be within 20 feet to clearly see what someone with "normal" (20/20) perfect vision can clearly see at 25 feet. It's good but not perfect vision
It means you have pretty close to perfect vision as 20/20 is considered perfect. Simply put, most people see at 25 feet what you see at 20.
25-30 v = -5

Your vision at 20ft is my vision at 50ft.

30 50 is considered mild vision loss, or near-normal vision.
