The present work was accomplished with the aid of Gullstrand's color mixing apparatus, and the author used his own practically emmetropic eyes for all his investigations. He reaffirmed that the curves for complementary colors for central and paracentral vision diverge from one another and cross in the blue-yellow sector. In a consideration of color equations and their influence by the yellow macular substance Olsson concludes that, as far as the study of central and paracentral vision is concerned, such a theory is untenable.
