Superhuman vision is possible
Jul 18th, 2007 by The Seer
In vision improvement, the golden standard is 20/20.
We define perfect eyesight as 20/20 vision. It has even entered everyday speech, e.g. “hindsight is always 20/20″.
What “20/20″ means is that a person is able to see at 20 feet (1st number) what a normal person can see at 20 feet (2nd number).
Those of us with eyesight problems might have only 20/60 or 20/100 vision i.e. seeing what a normal person can see at 60 and 100 feet respectively.
But you should have realised by now this “normal” eyesight is an arbitrary standard. It depends on the group of subjects that were tested when this standard was first established decades ago.
Superhuman vision is entirely possible:
Realizing that 20/20 does not represent perfect vision is important because many young healthy adults have visual acuities of 20/15 to 20/12.
If optical aberrations in the eye could be eliminated, the theoretical limit of foveal acuity would be 20/12 for a small pupil and up to 20/5 for a dilated pupil.

20/5 means being able to see at 20 feet what a “normal” person could only see at 5 feet. The limit of eyesight is far beyond 20/20.
The golden standard has been changed.
Now it’s time to change our mindset, we are only limited by what we think we can achieve.
Hi
Days ago I saw a TV report in mexican TV, about a research in Heidelberg Univesity, in Germany, about some kind of lenses that were use in combination with mirrors, to improve eye vision. This was a research intendet to improve plane pilots vision, but the report remark that this could improve in the future, any persons vision.
Unfortunately I did’t catch web site. Has anyone information about this?
thanks
I thought the whole 20/20 standard was because physically the eye’s ciliary muscle is at its most relaxed state while focusing at an object 20 feet away. Or in other words, the ciliary muscle simply won’t change when looking at objects 20 ft or farther away.
