I wouldn't worry too much about them. If the soak doesn't get them off - just wait for the next shed and work on keeping your humidity at 50% at all times until the next shed.
I'd actually recommend removing it...try using a damp Q-tip, but of course be careful not to damage the eye.
For every 15-foot python out in the Everglades, there are thousands of species of clams, trees, cats, grasses and birds that are wrecking just as much havoc across the globe. So, for all the headaches the snakes are causing, I at least applaud them for being scary enough to get people's attention.
