poor night vision

this is EXACTLY the same problem i have.  it's night time depth preception.

so i went to the eye doctor in the US (still have US health insurance and mine covers one routine eye exam a year).  i still have 20/20 vision, and officially i don't have any problem.  my dr. said that it could be going from close up computer work straight to long distance driving.  he said to give your eyese 10 mins between the two activities.

in my heart of hearts... i know this is the end for my eyes.  i'm 26.  both older sisters needed glasses at 25-28.  i will need them...
