Love me some collab.

[@Luckless] Thanks.  I try to keep mechanics simple but I always feel like there should be good with the bad, up with the down.

Light blindness sucks.  I played a character with that condition once.  It was quite restrictive.  In truth, I'm not going to enforce many mechanical limitations on you guys.  Instead, I prefer to trust my players.  So you are free to depict it however you like.  Consider it kind of like being in a dark room for a person with normal sight except your eyes hurt.
