Since, under rayleigh's criterion, the angular resolution is dependent on the wavelength of light, wouldn't blue light be more sharply focused by our eyes?

It would, except for aberrations. Your eye (mostly the vitreous humor) has considerable chromatic aberration:

1.8D corresponds to about 3% of the optical power.
