This model will produce pretty much any sclera color and or eye effect.
However, to use it as a normal eye color, you need to lower lora weight down to 0.1 and work your way up till you reach a full sclera color at 1.1.
For a better black and white eyes, I suggest combining this lora with Black Sclera Eye Style XL and or White Sclera Eye Style XL. Will dramatically enhance the processes.
