Your male sounds really easy-going for a deaf AND blind cat. Usually cats are really superstitious when they have this condition. Anyway, your cat should be fine as long as you introduce the young cat slowly. First, put the new one in a room by herself (except you) and leave her in there for about a week. This will give the male to find her scent without having to face her and so the girl can get used to her surroundings. Next, buy a cat pen that is large with a top. Place the female inside it along with food and water, etc. Place this in a room where the male commonly walks through. If he shows signs of stress, go back to phase 1 for a couple of days. When the male seems to pass the pen without avoiding or curiously searching it, you can let the female out. If the male is stressed go to phase 2 for a couple of days. Try to have different bowls, beds, etc. And, this is important, don't be stressed yourself. Cats tend to share/feel their companion's emotions. Hope I helped!
