Optics on the left, eyes on the right.
Scailon's, Tria's, and Combiner's.
Scailon's optic is dilated like it would be if he was in a dim room, it would be a slit if he was in bright light.
Tria's eyesight is excellent, almost as good as a hawks. And her night vision is almost as good as Scailon's (He cannot see that well in daylight though)
Combiner's is not as good as either, but is better than an average bots.
(Notice my sketch style changd slightly from one day the the next
? The top three (both of Scailons and Tria's optic) were done the day before the bottom three)
