That is a very good question. I do notice a difference between how cloudy
weather and sunny weather effect my vision, energy, mood and performance. My
body also reacts differently to different kinds of artificial lights. Standard
incandescent light works best for me. The "full spectrum" type of artificial
light doesn't work for me. Flourescent light is disasterous.

when I'm in Spain (further south and nearer the equator). It seems to be because
the nearer the equator I am the whiter the light is (the sun is white when it's
overhead) and nearer the pole I go the worse it is (For me that's North) (the
sun is more yellow when it's low in the sky). This has inspired me to learn
Spanish so one day I can move. My eyes are also better in drier climates as
clouds alter light in a way that affects my eyes badly but a clear sky is much
better. How does travelling to different areas affect your eyes?
