Yeah and even functional infrared eyes need to be at least twice the size of ours if not over ten times for more far thermal ranges. Anime eyes. The classic 20/20 D&D infravision would require eyes the size of basketballs, lol. Dark elves would put the innsmouth look to shame.
Larger than they would be for visible light, yes, but not necessarily larger than human eyes. Birds, for instance, can have amazing vision with much smaller eyes.
