You said you were concerned about eye wiggles with your contacts.
I have experienced dramatically reduced eye wiggles while wearing contacts, and I got curious.. I'll spend a bit of time searching for a link later, but as it turns out, contacts are one (somewhat successful) way of treating eye wiggles which can occur in some people constantly (albinos?) - apparantly the use of contacts increases feedback of the eyeball position and helps to stabilise it (sorry - hazy memory dulled by time. Will look for a link!).
I would recommend you take lubricating eye drops out with you, use them if you notice irritation, and also make sure you use them before you take your contacts out/before you sleep if they're night/day lenses.
