Eye issue

Well, last night I took a shower like every night before I go to bed, but last night, I decided to use some of our small bottles of shampoo that we got from hotels that we stayed at in the past. So as I was squeezing the small bottle of shampoo the shampoo, fell into my hand and then splatted into my eye. Talk about burn... It burnt for like 20 minutes in the shower as I rinsed out my eye with cold water. I placed a cold compress on the eye when I got out of the shower which seemed to relieve the pain of the burning, but seriously does it have to burn that bad. So I went to bed with a compress tied to my eye with a bandanna and I fell to sleep. Needless to say it burnt all night and I was up every two hours washing it out. This morning I woke up like a barn cat with pus in my eyes. I rinsed them out this morning and placed eye drops in the left one, that's all I can say is 12 hours later it still is slightly burning. My eye can't stop watering, which is good because it is flushing all that shampoo out of it. I guess, I just need to be more careful when I am using those little bottles, but I think I will stick to the big bottles they are less dangerous..
