With Bright Eyes, the character will be immune to blinding abilities. Darkness halves the accuracy of physical attacks, but has no effect on magic or many other abilities from the characters' unique skillsets. Therefore, even if some tough enemies like Ozma, Quale, Hades, and the final boss may induce this effect, if the player is using skills like Thievery or Dragon's Crest, Darkness may be of no hindrance.
