Since its inception, the International Research Group on Colour Vision Deficiencies (IRGCVD) has followed the policy that the Symposium Pro ceedings should be as close as possible to a complete record of the scientific content of the meeting. This policy has the advantage of providing an accurate picture of the current state of the art in research on color vision deficiencies, but it also has the disadvantage that papers typically span a wide range of quality. In this volume, however, we have instituted a system of peer review in an effort to enhance scientific quality as much as possible while continuing our past policy of publishing all submitted manuscripts. In addition to being edited for English composition and grammar, each of the papers included here has been carefully reviewed by an IRGCVD member selected for his or her expertise in the specific topic of the paper. Reviewers were instructed to include in their comments suggestions for improvement rather than recom or rejection. In our opinion, this review process mendations for publication has resulted in substantial improvement of many of the articles and has enhanced the value of the publication. We are pleased to acknowledge the efforts of our reviewers and offer them our sincere thanks for their important contributions to Colour Vision Deficiencies X. The Editors B. Drum, J. D. Moreland & A. Serra (eds. ), Colour Vision Deficiencies X, p. xiii."
