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?
20 feet!20 feet!20 feet!20 feet!
I am pretty sure that is very bad for u, I have 20-40 vision
20 x 20 = 400 square feet.
20/20
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.
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.
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.
Oh, dude, having 16/16 vision means you can see things at 16 feet that people with normal vision can see at 16 feet. It's like having a superpower, but instead of shooting lasers from your eyes, you just have really good eyesight. So, like, congrats on having eyes that work, I guess.
Having 20/100 vision means that a person can see at 20 feet what someone with normal vision can see at 100 feet. This indicates poor visual acuity and may require correction with glasses, contact lenses, or surgery.
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.
A vision of 20/70 means that at 20 feet you can see what a person with normal vision can see at 70 feet. It indicates moderate visual impairment, and you may struggle with tasks that require clear vision, such as reading or driving. It is recommended to consult an eye doctor for further evaluation and management.
No, 20/20 vision is considered ideal normal vision where a person can see at 20 feet what a normal person can see at 20 feet. A 16/20 vision means a person can see at 16 feet what a normal person can see at 20 feet, indicating worse vision.
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.
This is quoted from another question:"Having 20/60 means that you need to be 20 feet away from an object rather than a "normal" person who can see that object at 60 feet."http://wiki.answers.com/Q/Is_20-60_vision_considered_bad
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.
