from what i can find only one place in the UK sells false eyes.
they are 40mins drive from me woohoooo.
they supplied the eyes to wallace and grommit and supply alot of UK film needs.
they are sending me a catalogue out soon ( new catalogue due in 2 weeks) so should have a nice choice. i would post the website but its a couple of yrs out of date.
but if anyone in the UK wants the phone number PM me.
