Here's lookin' at ya

This evening I've been making eyes. I purchased 1-1/4" wood knobs. I drill a 7/64" hole clear through from the top to bottom to accommodate a brass screw for an axle. (The knob comes with a partial hole already drilled). Then I drill a partial 7/64" hole on the side to accommodate the spring. I paint the knob white with three or four coats of acrylic paint.

I print the irises on my computer printer and carefully cut them out. Then I glue them to the white ball opposite the hole for the spring. I'll finish them off with two coats of a clear glossy acrylic varnish. That will secure the iris to the wood and give the eyeball a wet shiny look.
