@hborre agreed. To my eyes when there is too much SSS and the skin gets lighter, it's just glowing and making it's own light at that point. That is the reason I don't use SSS on eye whites. For you to see any SSS at all the whites start glowing or I should say that they will not take any shadows from the surrounding eyelids/cheeks etc. I see that all the time with other renders. The eyes refuse to receive shadows and as a result look like they were painted in later in Photoshop.
