   Had my first eye surgery last Friday, fixing the cataract in my left eye. The next surgery on my right eye will be in about three weeks. The operation went fine and the hospital stay was pleasant. The only unwonted thing I noticed has been that my "new" eye renders colours in a more bluish and brilliant way while the other, the "old" eye on the right gives me the world in a sort of dirty-yellowish tone. This is an oddly feeling difference. The old eyes bathed the world in a warm light whereas the new eyes seem to render the world in a cold blusih monitor-style light. I already begin to miss my cataract. Perhaps I shouldn't have agreed to the surgery. I wonder how the difference in light sensation will impact my thinking and my sensing of the world. Pity.

     @simsa03 You're such an Eeyore. I liked the change after my surgery. The vivid colors in contrast to dingy sepia presurgery was rather like the exaggerated perception of color I experienced when I had unmedicated manic episodes back in the good ol' bad ol' days. I enjoy the heightened perceptions of mania, and its post op echo.

     Walking the earth, the world has a tinge of the colors of dream. Again. Dangerous colors. I think thoughts in color.

     @simsa03 One eye sepia, the other blue steel.

     Yes. And I can't help that I feel strongly the atmospheric difference that like effects my mood. It's almost as intensive as some odour in the air, flashing up memories from past and future.

     You give me my right eye, not my left. :-) Perhaps I skip the second surgery?

     @simsa03 Don't do that. Aside from your color preference, you'll eventually be blind in the cataract eye. You'll be like my old dog, who is mostly blind from cataracts, and walks into walls and gets stuck in corners.

     @simsa03 One possible reason to our different reactions to the result of the cataract surgery may be due to my protanopia (remember discussing Van Gogh's posited protanopia?) We see colors differently.

     @simsa03 And why are they called cataracts? The other meaning of cataract is a waterfall from a high precipice.

     In Greek, καταρράκτης means "waterfall". The connection was already established long before Galen. The assumption was that in the development of a cataract substances run down behind the pupil – perhaps what we nowadays call floaters – and that the visual impression was like "seeing through a waterfall".

     This may be a reason why to you the new visual impressions don't come across as steelish or bluish. I don't doubt that I will adapt but I muse about the impact on my thinking and perceiving. Will both get harsher, more either-or, this-or-that, clear-cut? Will ambiguities and vagueness, very important to me ("Let the complexity of the world be"), disappear and be replaced by dumb single-mindedness? I find that a scary possible long-term outcome.

     Good idea. Thanks. I'll think about that.
