It makes no sense for the eyeball itself to be tougher than the surrounding tissues. Those membranes in all animals exist to protect the eyeball, which is fragile and easily damaged. As Kaneki notes, even ghouls are vulnerable there and he tries for an eye-strike when his kagune fails to do much damage to Shachi.

As I mentioned, you're mistaking Yamori injecting into the mucus membrane as meaning ONLY that part is vulnerable. That is not the case, it's a simple matter of basic anatomy -- injecting into the tear duct is one way to quickly get any substance into a person's system.
