can you see?

Can you see??  I've heard this phrase several times this week as Zoe laughs her little head off and gives me eye tests.  She thinks it's so funny to give the tests to others, and I have to laugh as well...  She had "real" eye tests last Monday and there isn't anything new to report, which is good in one sense.  The pallor on the left optic nerve hasn't gotten any worse and her vision in that eye remains 20/25, thank heaven.  The right eye is about the same - she seems to sense light, but can't "see"...
