Character eyes are underexposed in a lot of scenes problem

So I'm having dark eyes in a lot of different scenes. Making the environment super light doesn't help either. Nor moving it to the 0/0 cordinates.
Any idea what might be the problem?

Thanks in advance

Iray? Have you, or a preset, adjusted the Max Path Length setting in the Editor tab of the Render Settings pane? The default is -1.

On Iray yeah. It was on -1 earlier (same darkness in eyes) I've put the Max path length on 5 as I read it might help. But so neither 5 or -1 make a difference.

5 (or so, depending on mateials) is the minimum that will allow eyes to work. -1 is unlimited, so that isn't the issue. What happens if you do a spot render (Tols>Spot render, drag over the target area) of just one eye, with as little surround as possible?

Same result. It's not like one eye is less dark. 
What does help is putting the environment map and intensity higher. Then eyes become normal. Problem then is that my whole scene is overexposed. The middle way here isn't great either. But it's promising. Maybe I can try a bit more stuff in render settings.

At the same time, you better check the settings on Sclera surface in Surfaces pane, esp. Translucency relevant slots, as well as Diffuse, Color, Refraction related slots....

For a quick fix, apply a different set of eye materials. Like @crosswind I imagine the issue is with the sclera settings (possibly refraction).
