The red eye effect happens when flash reflects off the retina. Compact cameras (film and early digital) had flash very close to the lens, so there was a high chance of that happening.
Not much of a chance these days, when most people take photos with cell phones, the cellphone cameras have adequate low light performance so you don’t need flash to begin with, and the “flash” is just an LED that isn’t as luminous as a real flash bulb.
