In some sorts of lighting, some people's eyes do become more vividly coloured, so you can get close to the literal effect if the pupils become smaller and more of the iris is visible. Alternatively, if you just open your eyes a little wider you can get a similar effect.

Apparently there's an instinctive response in humans where we raise our eyebrows for a fraction of a second when we see someone we find attractive. That might give you lighting-up eyes in both a literal and a metaphorical sense.

Or you could be a cat.
