Try progressive contact lenses, I can see the front sight again.
No one has answered your question yet. I have not worn this set up. You can get this made for you. I assume you want the single vision lens over the dominate eye to be prescribed for the front sight distance (and the non-dominant b/f is your regular distance rx with your near add as the b/f). This is going to be like mono vision, one eye at distance and one at "near." In your case "intermediate" distance.I wear bifocals and my front site is fuzzy unless i tilt my head back. I was wondering if anyone has tried changing to a bifocal in one side and a regular lens for the dominate eye.

The critical thing is to get the exact rx for the single vision lens and that requires that you bring the subject up with your optometrist. You also need the exact distance from your eye to the front sight to dial in the phoropter at the docs office.
All that being said, I don't know that you will like the outcome.

Are you going to be wearing the special glasses in a self-defense situation?

Couple ways to go about this. You can do what Objohn says and have the bifocal put at the top of your lens.

Stick them on your glasses in the spot you need them. Take them off when you're done.
