I have seen and done it, but i never recommend it unless it is a last resort because i am afraid people will do it wrong. And i think if you talk about this method, you need to elaborate before people mess up their snakes eye by putting tape on it. You have to be very careful! If you use tape, be sure to stick it on your hand a few times first. It can be too strong directly, and you don't want tape stuck on your snakes eye as well. I have never heard of people using scotch tape though, i have heard of painters tape being used because it is less strong and easy to remove. (There are however more types of scotch tapes and i am not sure which you meant) You soak the eye, and dry it off with a paper towel. The best way to make sure the tape wont stick to the scales, is using a q tip with Vaseline on it and gently grease up the scales around the eye. Slowly let the tape drop on the eye cap, do not press down on the eye. Check if the tape took, and gently remove the tape in somewhat of an angle. If the tape comes off too easy without taking the eye cap with it, either soak it some more or try a slightly more sticky tape.
- I would not recommend trying this technique unless really -Really- necessary, the 2 times i did it the snake had multiple layers of caps over the eyes.. And they would not come of any other way... This method did work for both snakes, it is however very uncomfortable because you have to restrain them. It should only be used as a last resort to clear the eye, usually waiting for the next shed or any other method works fine.
