I have had this problem all of my life. Sometimes I even wear sunglasses at night, when I am driving because the on-coming headlights of passing cars becomes too much for me. My friends and family think I am crazy but no one can argue about my ability to see in the dark. The headaches are a bit of a bother, but generally speaking, I am proud of my nightvision. I have 20/10 vision, and everyone else in my family is wearing glasses. I'm really only asking out of curiousity. Thank you.
