: For the past week I have been losing sight in one eye. I get a light headed feeling and one eye just goes dark. This only lasts a few minutes and my vision clears up again although now that one eye is a little bit more light sensitive. Does anyone have an explanation?

This sounds serious and should not be taken likely. Go see your local optometrist so that he can check you for signs of Glaucoma and or Retinal damage.
Are you taking any new medication? Sometimes this can effect your vision also.
