I don't know what kind of dwelling you live in, so this may not be a viable option for you. My brother in law has severe allergies. He comes in my house and his eyes run a lot because of my kitties. He has this problem in other places as well. In his previous place, they weren't allowed to have pets inside. They adopted some kitties that came up as strays. The kitties did come inside periodically but not to stay for very long. He and my sister have recently moved into my brothers old house. They brought their 2 kitties and have them inside now. In addition they have adopted one that was hanging around there between the time my brother moved out and they moved in. The cats and also the wood stove don't bother his allergies hardly at all. The only thing that they can attribute it to is that my brother had an ultraviolet filter installed in the central heat/cooling system. The say that these filters work very well for allergens and that's the only thing he can figure since now he has 3 cats living inside his house. He comes over here and still has a reaction. I will see if I can find a link to the product online. I know my neighbor sells and installs them.
