Salut, salut here is the product of a bounty I recently finished. This LoRa gives extra eyes in the forehead area to any character(I only tested women). I might update this to give the option of columns of eyes(Think Rachnera Archnera) or eyes in a row(think Muffet from Undertale) but right now it picks one of those or combines them which I think is cool.
I tested this on a few different checkpoint and seems to work reliably enough. Also as you can see it works well enough with character Loras(simple ones like the Pokemon girl ones and more complex ones(See Blue succubus). The trigger word is "drider_eyes" but you may need to emphasize the word. "Extra_eyes" and "forehead" can also help depending on your checkpoint.
Example prompt: 1girl, black_hair, red_eyes, <lora:DriderEyeV3:0.99> (drider_eyes:1.3), (extra_eyes:1.1), black_dress, short_hair, forehead
