Our Phoenix sun is brutal on wiper blades, for sure. Usually have to be replaced annually. I am, however, a huge proponent of waxing the glass. Been doing so over 30yrs, and I think it was a late uncle that taught it to me. He'd had years of driving a truck interstate. I apply it, buff it off, and repeat at least twice a year. I can get through normal storms with sometimes no wipers at all, so long as my speed allows enough inertia to let the beads roll up and off. In our occasional driving rain, wipers don't have to be maxed-out. Another plus is that it prevents the small asphalt pebbles that are kicked up from causing chips/cracks, or at least mitigating the damage they might otherwise cause.
As to glare, I suspect that has much more to do with the vaporous deposition that occurs ON THE INSIDE of the windshield. It's a huge pain to clean off, due to the convex curve and the hard-to-reach spots. I seem to get the best results from the solution at the typical gas-station, same as you'd do on the exterior. Just lay down a layer of their cheapo paper towels on your dash first, to absorb most of the slop. Use the squeegie, too, and save your energy to get into the tight spots with your hands.
