I use 3D eyes that are counter sunk into the lure. This gives a good look and protects the eyes from getting ripped off too easily
First I mark the location using the lip slot as my reference point to measure off off.
I use masking tape to mark my counter sink bit so both eyes are of equal depth. You could just use a this bit but I like to add a little character to my eyes. I have a a few sanding stone bits I use for this. Same process mark the depth with tape and round out the eye sockets to that depth. You can tip the bit and go for an oblong eye socket if you wish
