I agree, wet cotton buds are better, gently wiped from front to back. However, there is an easier method than that or tape – a rubber counting thimble. With inexperienced keepers using tape, they may possibly end up using it on an eye without a retained spectacle. For example, looking at the slough, head scales up, the left side belongs to the right side of the snake and vice versa. If you are stressed out at the time you can make silly mistakes like that first up. Anyway, let’s put people’s suggestions together as single set of instructions. We shall leave tape to the more experienced practitioners….
To remove retained shed and/or a retained spectacle over an eye
Examine the slough to determine which areas of skin are missing from the body and tail tip. Now locate the unshed areas of skin on the snake. You can, if you feel the need, mark the unshed pieces with an indelible (water proof) marking pen. Now carefully inspect the eye areas of the slough to determine if one or both spectacles have been shed or retained. Now examine the snake and locate the retained spectacle(s).
Soaking in tepid water (around 30[SUP]o[/SUP]C to 35[SUP]o[/SUP]C) is important to loosen up the old skin, including retained spectacles. This can be achieved by placing in a shallow container of water with a lid and holes for 10 to 15 minutes, keeping a constant eye on it to make sure it does not inhale water by accident. Alternatively, place the snake in a damp cloth bag, at the same temperature, for half an hour or more. Calico is better than cotton as the rougher fabric helps remove the softening skin. Towelling is even more effective. So if the skin has not come off after soaking in the bag, allow the snake to wriggle through damp towels while you hold it. Repeat the soaking if needed.
Often a retained spectacle will come off with the above procedure. If it does not, then take a rubber counting thimble and squeeze it (finger end pointing out) between your thumb and you fore-finger. Holding the snake’s head with your other hand to clearly expose the eye, draw the thimble gently across the eye, from front to back. The rubber produces enough friction to grasp an unshed spectacle but is flexible enough not to damage the eye underneath.
