Omega Delta () is an American professional fraternity for students of optometry. It was established in 1917 at the Northern Illinois College of Optometry and expanded to include thirteen chapters.

History Omega Delta was formed locally on May 21, 1917 by students C. I. Josephson Jr. and L. Gessett at the Northern Illinois College of Optometry. It was originally a male-only professional optometry fraternity created to support scholarship, develop high professional and ethical standards, and create a fraternal relationship amongst its members.

Omega Delta Fraternity of Optometrists was incorporated in the state of Illinois. It expanded to be a national organization with the addition of the chapters at Needles Institute of Optometry and Los Angeles College of Optometry in 1919.The Focus Yearbook, June 1933 Northern Illinois College of Optometry It was governed by a grand chapter, with five officers who are elected at national conventions or special conclaves, including grand president and grand secretary/treasurer. In 1929, it held its fifth annual grand chapter meeting during the American Optometric Association's convention. At the time it had seven chapters.

In 1930, the fraternity started publishing its annual magazine Omega Delta News. Its activities included sponsoring educational lectures and hosting a variety of social events. For decades, the Iota chapter at the Southern College of Optometry sponsored an annual dance, Year and a Day, that honored the college's graduating seniors and commemorated the return of its students from World War II. Chapters also tutor and host mock proficiencies, helping to prepare members for professional exams.

By 1963, Omega Delta had chartered thirteen chapters and had initiated 3,975 members at optometry schools across the United States.
