What do 20/20 and all those numbers mean?
The standard by which all eyesight is judged is referred to as 20/20 vision. This is regarded as “normal vision” and describes what someone should see when standing 20 feet away from an eye chart.
If you are diagnosed with 20/40 vision, it means that at 20 feet – you can only see the details that a person with normal vision sees at 40 feet. In reverse, if you have 20/10 vision, it means that at 20 feet – you can clearly see what most people can only see at 10 feet. That makes your vision better than the average standards!
Can people have better than 20/20 vision?
20/10 vision is thought to be the maximum visual acuity of human eyes without binoculars or other magnifying devices. Recent advances in optics have led to the creation of corrective lenses that can provide this ultra-sharp vision.
It seems that the best eyesight ever reported in a human was in an Aborigine man with 20/5 vision! To give you an idea of how clear and far he could see, his vision measurement compares to the natural sight of eagles. From 20 feet, he could perceive the fine details that most people can only see from 5 feet away!
