Double aspherical 1.74 lens thinning Vs Glass 1.9 lens thinning?

I have a prescription of sph-10D

At the moment my glasses do distort my eyes quite a bit, and I was looking for a way to reduce this.
As far as I understand, increasing the refractive index of the material just thins the lens and doesn't actually reduce distortion (because the power is the same).

However, apparently the new double (versus single), aspherical 1.74 lenses reduce the distortion, and hence although they will be slightly thicker than the 1.9 glass lens, will not make my eyes look as small?

Is this true?
Can someone explain this to me, and help advise me on which lenses to pick.

Thanks
