I have the same issue where my eyes are so senstive I just want to shut them. When driving in sunlight or daytime I must wear sunglasses or else they will water really bad and cause under my eyes to get very irritated and raw. I was given a prescription for some drop the eye exam  place gave me,but I never filled it, but now the problem is worse this summer so I meet with an allergist down here to see what options I have. I will try the Alaway for now though. The only thing that stops my eyes from itching, closing shut, etc is if I take a benedryl and do the cold and ice compresses. I sure can't stand these allergies....
