 Improved sight after surf swim?

I'm myopic (short sighted), and years ago, when my eyes were first
deteriorating, I noticed a strange phenomenon at the beach.
Immediately after swimming in surf, my sight would improve for a few
seconds, almost to the point of normal vision (I'd use this method to
check where my towel was on the shore).

Would this be due to the sea water on my eyes briefly acting like a
contact lens? Is this a documented phenomenon?

Edith offers:   The  power of my damaged eye was at 400 back in the early 90s, which
means I couldn't see a clear face across the dinner table.  Once, on  a Florida  
beach for many hours back then, I lay down for a sun bath without my glasses on and
was astounded that I could see the pelicans flying over me at a height of about  200
feet quite clearly.  It was like a miracle.
   It lasted all the time I was on the beach.  At night the eye returned to its
usual 400.   When I told my retinal specialist about this a couple of months later,
he was quite unimpressed:  He said it was because the intense light had caused
the eye (like a camera) to close down to a tiny opening....If you take a piece of
dark cardboard and poke a tiny hole in the center, you will have the same experience.
   With a pinhole to see through one sees a tiny area,  even at a distance,  much
more clearly, even without  glasses.  
   Nonetheless, the next time I go surfing, I shall open my eyes under water to
see if your sea water rinse will help me.   Anything that works.....

It has to do with the way that the tear layer (sea water added to it) forms
in your eye.  I've got astigmatism, yet whenever I get water in my eyes, it
seems to go away unitl I blink my eyes a few times, and then it goes back.

which is also why hard contact lenses correct corneal errors, tears
filling the space behind the lens with any errors there ...

could it have anything to do with the osmotic gradient of salt water
pulling fluid from the cornea thus effecting the refraction of the
same?
