No. Not really. "Normal" vision is around 20/20 or 20/30. 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. At 20/60 you should still be able to function with everyday life and only need glasses to drive or to read a blackboard at school. 20/60 is only a mild impairment. 20/30 to 20/60 is considered mild vision loss, or near-normal vision 20/70 to 20/160 is considered moderate visual impairment, or moderate low vision 20/200 to 20/400 is considered severe visual impairment, or severe low vision 20/500 to 20/1,000 is considered profound visual impairment, or profound low vision less than 20/1,000 is considered near-total visual impairment, or near total blindness
Your vision at 20ft is my vision at 50ft.
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
20/100 Vision would mean that the average person can see clearly at 100 feet you must be 20 feet away to see the object clearly.
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 that u can see at 10 ft what an average person sees at 20 feet. and the average vision is 20 20
