There are a few "progressive" contact lenses as well. I use Air-Optix with great success. They are NOT weighted for orientation but (I believe) have a radial variation in power, and somehow your optics processing center learns, very quickly, to use the reduced power info for short-range work and the full-power info for distance viewing.
That said, the day either medication unstiffens my natural lens or a focussable artificial implant is approved, I'm going to jump at the chance. In fact, I'd prefer the latter so I can dump my -8 diopter contacts!
