Try this:
Stand about 6 feet away from someone and look at his/her right hand. Then ask the person to wave that hand and see if you can see it.
If you can, chances are you can see enough to do a kote (wrist) strike.
I am choosing kote because it is the smallest target you would strike.

Mathematically:

Assuming you are roughly 6 feet away and need to be able to see the opponent's kote, which is say 1/3 foot in height.
That constitutes an angle of 3.179 degrees.
Now a person with 20/20 vision has an acuity of 1 minute of arc - ie 1/60 of a degree.
A person with 20/200 has an acuity of 10 minutes of arc - ie 1/6 of a degree.
Since 3.179 is 18x greater than 1/6 of a degree, theoretically that means you should be able to see the kote.
