Eye color doesn't matter in vision, it's not part of the optical path, its role is the same as an aperture on a camera lens.

Ok it seemed to me that that the stroma of blue eyes scatters back more light: https://medium.com/@ptvan/structural-eye-color-is-amazing-24...

Yes, scatters it back out — that light does not enter the pupil or contribute to what that person sees (save probably a vanishingly small amount that is re-scattered in the cornea, which is totally de minimus).
