The best way to make the lenses is to sculpt the frames, or to get them from someone who already has. Use some clear vinyl for the lense area, do a little bit of black airbrushing on the outside edges that will but up to the frames. Get some silver screen mesh, I suggest going to a target or wal-mart and heading to the cooking area. Find sifters and get a few of those. Cut the eye shaped mesh out of those and put them in behind the clear vinyl, glue it all together and your good to go.
