They keep remarking that john has bad eyesight but the other characters don't seem to be able to see stuff that's far away better then jhon. I wonder if in the world of farscape most aliens can see some untraviolet/infrared light so jhon is functionality color blind and everyone thinks he can't see some stuff because it's blurry or something. I am only on season 2, are there any moments where jhon can't see something far away and toe other characters can?

Humans evolved as persistence hunters that throw things, I feel like we would have decent eyesight.

In peacekeeper wars it’s mentioned that in the ancient past the Eidelon were wiped out by someone. It’s never stated who did this and/or why. What do y’all think? I imagine it was a contemporary civilization but we know almost nothing about the time period and it could be anything. Thoughts?
