While allowing the snake to soak is a good idea, placing artificial tear drops, available at any pharmacy, works very well, as the solution is hydrophilic. Do NOT attempt to use any instrument to remove the eye cap, unless you have the eye hand coordination of a vascular surgeon!
For the best and safest result, hydrate the offending eye cap very well using water or the artificial tear drops and use a small piece of Scotch tape, not masking or duct tape, and roll it across the eye in the same direction it would come off naturally..
Good luck,
