Shortsightedness.

This is not a problem I have.  I am fortunate to have good eyesight.  But it is a problem for many of my students and Chinese co-workers.   I was made aware of the problem when I was walking the ground of a big Wuxi Middle School.  In the Center of the campus, there is a large artificial lake.   A bridge crosses the center of the lake.  As I crossed the bridge, I saw large birds wading at one end of the lake, probably about 100 meters from where I stood.  I pointed this out to the Chinese who were with me and they told me they couldn't see the birds.

I wonder what it is like to for a short-sighted person to look at a photo of a wide scenic vista say of mountains and valleys.
