user27148: Right now "vision" is synonyming into "eyes" which to me is backward...there are a lot of vision-based questions that aren't really about eyes per se, whereas the inverse is not true. I don't know if these are automatic categories based on frequency or something and I don't oppose them being synonyms, but I think "vision" should be the dominant category and tags for "eyes" should convert to vision, rather than the other way around, if this is possible.

user9943: I have de-synonymized the vision and eyes tags. Honesty, I do not know why, how and when the synomyzation happened. 
The vision tag is more appropriate for questions on visual function, physiology and neuroscience.

Questions regarding how the brain interprets information from the
  eyes. Consider using the "eyes" tag for discussion of eye anatomy,
  physiology and evolution.

The eyes tag is more appropriate for anatomy, histology and underlying (physical) optics questions. 

The discussion of the anatomy and evolution of eyes. Consider using
  the "vision" tag for questions regarding how the brain interprets
  information from the eyes.
