SEW can be a rare trait even if it appears (as far as we know) that SEW will only get SEW children and not "normal" ones.

We know that Salem actively hunts and kills them meaning that only few SEW live long enough to have children of their own. This would mean that after you kill the last SEW, it is impossible for new SEW to be born. Sure, if Salem wasn't killing SEWs, eventually everyone (or at least majority) would end up having silver eyes in the end.

The other possibility is that the silver eyes are relatively new trait (in genetic sense). Lets say that Ozma's silver eyed kids were the first SEWs and after them there has been 20 or so generations (1 generation is 25 years so 500 years. Enough time to make them legendary). If we assume that every SEW had 2 kids, the total population of SEW at present day would be around 16 777 216, which is a little less than the population of Syria or about the double of NYC's population. That might sounds a lot, but in real life, that is less than 0.22% of the world's population. Sure, it's likely that Remnant has a much smaller population than ours but even then, I don't think SEW population would have been more than 1% of the over all population, making it still a relatively rare trait.
