The pupils are rather small. For what light conditions are there eyes made? Do they have a tapetum lucidum? Are they trichromatic?

The small pupils are just an aesthetic choice in this case: makes the stare more disconcerting. Focco are mostly diurnal, but have excellent night vision - much better than humans. They do have the reflective lining in their eyes, and are trichromatic - but the third pigment is an independent mutation and not tuned to the same wavelength as the Terran primate one, so the triadic displays made for human and focco vision look "off" to the other species, respectively.
