Well, visual acuity could potentially be surgically corrected. I'm not sure how relevant height is, exactly, but I'd be willing to bet a larger range than that could be accommodated in the right circumstances.

Then again, if you're genetically blind or have dwarfism, that may not be the case.

I think GATTACA is less about genetics setting a bar, but that the bar is constantly getting raised until it will eventually be unreachable without artificial enhancement.
