Sometimes, but not for walking around - unless I'm at a shopping centre with all the fluro lighting, then I wear my bifocal prescription sunglasses as it interfers with me neurologically.
I was interested in this comment "I have been experiencing for almost two years a CONSTANT feeling that is like a head rush or weird feeling when you stand up with high blood pressure" because you usually can't tell when you have high blood pressure. That sensation is actually due to your BP dropping when you stand.
I think that you definitely need to drink more fluids, maybe also try some rehydration fluids such as Gastrolyte or Hydralyte = not sports or energy drinks, or soft or fruit juices.
Maybe try some chilled coconut water. The canned ones with pulp are nice.
