if this is V4 just download my free eye shaders and your problem should be fixed. If not V4, you can still apply the shaders to the eye parts manually and replace the V4 maps with appropriate ones. FYI the blue parts are coming from SSS in the eye whites that, IMO, is totally unnecessary for the eye whites to look correct. The glassinyness is prbably too much reflect. https://sharecg.com/v/88803/gallery/6/Texture/Ghostship-Eyes-REV2
