Snakes cloud up prior to shedding, but "go clear" (look very normal*) right before they actually shed. You didn't find the shed because he hasn't undressed yet, lol.
*A snake's body actually secretes some fluid between the old & new layers, making it LOOK like they've already shed, but they haven't, & yes even their eyes will clear up.
And it's not a dumb question...not many creatures do weird things like snakes do...that's why they're so interesting & fun to know.
