Does this only affect people with Blue eyes ? As someone with utterly black eyes, I don't have a problem looking at glowing blue signs and don't find them fuzzy either.

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).
