When im outside, open spaces, places with lots of things like store shelves, moving car, and any place with white lights including daylight i get lightheaded, have trouble focusing eyes and visions gets cloudy, what could cause it?

Your symptoms are suggesting a condition from the migraine/light sensitivity spectrum. Try to wear migraine glasses to see if helping. Mention to your doc during your annual exam so that it can be clarified and treated properly.

It is not feasible to provide an opinion without additional history, physical examination may be some tests. It would be prudent to see your doctor to see if you may be depressed. Depression is treatable. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water. Wish you good health!
