I wonder how they get those "hole-in-ones".


I have 50% vision in one eye (construction accident).  I commonly
drive with an eye patch in daylight.  For driving, depth perception
with one eye is no different than with two.  My eye doc told me that -
said that deph perception only functions at close range. I didn't
believe it but it is true.  Try it yourself.  Close one eye, look at
something more than 20 ft away and you will see you can accurately
guage the distance.  Now at short range, such as parking, it is a real
problem.  I cannot tell within a couple feet how close my car is to an
obstacle.

So you didn't even try the test?  What part of being able to
accurately guage distance with one eye did you miss?

You didn't answer my question.

Again:  "How do the golfers get those hole-in-ones" if there is no depth
perception after 20 feet of distance. I haven't seen the measuring tapes
out.


Your statement is physically impossible with only one eye. You are imagining
the depth perception based on your memory of object sizing. It's just crap.
The science centres typically have depth perception challenges that
disproves your theory.

Do you know any golfers that can hit a hole-in-one, every single time, on a
hole they've never played before?  Or every single time on a hole they've
played a thousand times?  If not, your argument is void.

Diminution of differential binocular vision with distance can be shown with
simple math.  I don't know the cutoff angle -- not my field of expertise --
but I wager it's closer than you think.


I had partial vision loss in one eye for a long time (regained with surgery
a few years ago, yay).  You can get a sense of distance using only one eye,
all you do is bob your head back and forth a little so that you get two
viewing angles on the same object.  Sense of depth isn't quite as good as
true binocular vision, but it's much better than none.

 


The question was an example of a person displaying his stubborn
insistance that he knows he is right without tryign a simple test.

I'll take the word of a eye surgeon over someone posting on the
internet any day.   I'll also stack up my personal experience against
someone who won't even step out the door and close one eye.
