You never mentioned how old you are, but your eyeballs do change with age.

Went to reading glasses about three years ago when I had difficulty reading magazine print (various colors), although I could still see black and white print fine. Also low-light conditions hampered my vision.

Just had an eye exam last week, and I am now being fitted for bi-focals. This from a guy who had 20/10 vision until the age of 44!! Kinda sucks, but it isn't the end of the world.

Definitely have your eyes checked!
