Alternative to resin eyes?

Hey there guys! I'm planning a suit for my fursona, but her eyes are wide-set so I will not be looking through them. I plan to make use of the tear ducts similar to how a resin head is assembled. Though, seeing as my fursona also has large, bulbous eyes, I don't want to opt for resin. I'd like to use some kind of material (preferably shiny, but not super important) that I could paint or that is pure, fully-red. I plan to put a plastic "bubble" over the eyes for that extra effect. I've seen a couple suits with reflective eyes also, and I have no idea how they do that, but that would be awesome. :o
Speaking of which, any good sources for clear plastic half-spheres? I have a couple, but one set is hazy and the other is very thin plastic, and I'm afraid of scratches or warping. :c
