I get hypomanic or manic every June from the sun. I have used orange glasses to block some of the extra blue light (the same light that helps SAD) and that helped back when I was working and getting sun for many hours of the day while working (I did home health so I was in the car about 4 hours of the work day plus I commuted a long way so LOTS of sunlight.) They aren't pretty but they do help.

Am I allowed to post links here? Because I can send you to where I learned about this and where the glasses come from (they have to be a very specific shade of orange) if I'm allowed. It gives more explanation than I necessarily can and the link to the place I bought mine (they were pretty cheap, $7-8 I think). They aren't perfect and I have still had June issues even when I'm not out as much in the direct sun but they do help some for me and maybe more for others.
