My headlight lenses had deteriorated to what yours have. I couldn't see chit at night. The occlusion makes the light go in all directions except where it needs to go. I don't remember the brand I ended up with. Possibly "Eagle Eye" which is a chinee cheapie OEM replacement popular with body shops and rebuilders when cost is a concern. About $45 for the pair, took a couple hours to install, and I can see where I'm going at night again.
You're making progress. Keep it up.
