I've been getting my eight hours of sleep during the day rather than the night for seven years now because I'm so annoyed by sunlight and feel so comfortable and alert at night.
Also, I don't know if it is a typical benefit of photophobia, but yes, I have excellent night vision. It seems as if my pupils dilate very easily while contracting is more difficult.
