So the title is pretty self explanatory in my opinion.
i think that such an idea needs to be mused upon. On the one hand being a spider who is missing an eye wouldn’t be so bad given the knowledge that you have many replacement eyes around your face. but at the same time what would an appropriate eye patch look like?
I think that it would look something like the torso/leg harness for mountain climbers.
less refined patch detail and more strappy, like magnified fish netting. crisscrossing around the eyes allowing for ocular visibility but providing appropriate cranial support of the eye patch.
Not as simplistic as the typical pirate style patch, more akin to wearing an Octopi diaper on your face.
It grows more philosophical now though. On the one hand, more eyes means less of an impacting blow that accompanies a loss of an eye. But more eyes means more chances to lose them.
So we can safely assume that the more we have, the more we are able to lose.
