Well, Dave Barker also tends to agree about the eyelid statement and pythons, bang away.

Bottom line is this: If someone handles a venomoid gaboon viper and its within range of your eyes, which with a gaboon could be down by your waist depending on how large the gaboon is, getting a hit in the eye is possible. Its a consideration someone should take into account before they decide to free handle any venomoid with large fangs.

If you stop banging your head on things you'd probably see this.
