From an accessibility standpoint, could you consider making the blur a toggle or slider in the Settings Menu? It could be called "projector focus". Could be on by default but turned down or off for those who need it, could even turn it up to be silly.

Ooh, that's an interesting approach! TBH I added a slider for the blur this week and now I think I prefer no blur, so I'm considering making that the new default or cutting it entirely. But you've given me a couple new things to think about - 1. Having the radiation level affect visuals in the lab and 2. Possibly introducing different rendering fx based on each monster's unique features...
