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.
Do You mean 20-20 vision?
I am pretty sure that is very bad for u, I have 20-40 vision
20 feet!20 feet!20 feet!20 feet!
20 x 20 = 400 square feet.
Normal vision is typically defined as being able to see objects clearly at 20 feet that an average person with normal vision can see at the same distance. This is often denoted as 20/20 vision.
20/20
It means seeing at 20 feet what a person with normal vision sees at 20 feet. A person who has 20/40 vision can see at 20 feet what the person with normal vision sees at 40 feet, etc. Some people have better than 20/20 vision.
20/10 vision refers to vision better than 20/20. A person having 20/10 vision would be able to see something at 20 feet that a person with 20/20 vision would see at 10 feet.
Having 20/15 vision means the person can see at 20 feet what an average person can see at 15 feet, indicating better than average vision. In comparison, someone with 20/20 vision sees at 20 feet what an average person sees at 20 feet.
Normal vision is 20/20 vision, or in metric 6/6. This means that when you are 20 feet away from something, you will see what someone with normal vision would see at 20 feet away. With 20/40 vision, you would see something 20 feet away as someone with normal vision would see it at 40 feet, so therefore it would be blurry. 20/100 is also possible and 20/200 is considered legal blindness. 20/10 would be better than normal.

Do you mean for eyesight?20-20 vision is average vision of human what he can see normally from 20 feet away as a standard.If 20-40 vision, that means you have to stand 20 feet away from an object that the average person can distinguish from 40 feet away.If 20-15, that means you can stand 20 feet away from an object that the average person can distinguish from 15 feet away.
If your vision is 20/16, You're above average because you can see an object from 20 feet that a normal eye sees at 16!But, If it's 16/20, You see things at 20 feet, that people see at 16.
Having 20/10 vision means you can see at 20 feet what a person with normal vision can see at 10 feet. It indicates better than average vision and means you have sharper visual acuity.
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
You are able to see at 20 feet what others can see at 10 feet. In other words, you can see more clearly from a distance than others. It is not uncommon to have eyes with different vision properties. You can be 20/15 in one eye, and 20/20 in the other. 20/30 = you see the eye chart as if it were 30 feet away 20/20 = you are 20 feet away from the eye chart and you see normally (baseline) 20/10 = you see the eye chart as if it were 10 feet closer
All 2015 means is that a person with 2015 vision can clearly see somthing 20 feet away that most people would need to be no more than 15 feet from. To this end, it is better. A person with 20/100 vision can see something 20 feet away that most people could normally see 100 feet away. --Yes, 20/15 is better vision than 20/20.
