a7c5f4f206Using Eevee with Glass Refraction is getting a weird visual bug.
Please see the attached images and blend file.

Sorry I miss report , it is caused by plug in, which try to hide refraction part in modifier,
to remove eevee bug, then could not render correctly.

This is a limitation for screen space refraction.
To do this kind of effect in eevee (cornea refraction) you should do the refraction inside the surface shader and not using 2 meshes. This is quite complex and is outside the scope of this report.
So, we can't have realistic eyes in Eevee?

@istoltoto: Sure you can, if you do what @fclem suggests - do it inside the surface shader.
If I do the refraction inside, where I put the texture?....I'm confused...
And using only one mesh will look something like this.
What I think about these covered (complex?) eye meshes ,
I can only use transparent BSDF with mix reflection shader to show reflection.
though it not correct way, but at least it show some reasonable eyes.
all other blender offered default shader which count ior for refraction not work. or I need to modify mesh without covered part for Eevee.
(refraction bsdf, principled bsdf with transmission , glass shader)
even though I set ior as 1.00 for refraction.
