The word "more occluded" means something is becoming more blocked or obscured. Its antonyms are "open," "clear," "unobstructed," "transparent," and "visible." For instance, if a road is more occluded, it's hard to see or take the necessary steps to avoid an oncoming vehicle. Conversely, if a road is open or transparent, it's easy to drive without any hindrance. Similarly, if a window is more occluded, it's tough to see through it, and the view is unclear. Yet, if a window is clean or clear, it's easy to look through, and things outside appear visible to the eye.
