Welcome to the Illinois Eye Institute (IEI). IEI is a nonprofit multi-specialty eye center that provides comprehensive eye care to individuals of all ages from the Chicago area and beyond, regardless of their financial status. It is designed and staffed to meet general ocular health and visual needs and provide highly specialized optical services.

As the clinical division of the Illinois College of Optometry, IEI is a leader in eye care education and research, a clinical training ground for students and residents, and a resource for continuing medical education for eye doctors around the world.

The IEI is among the largest providers of vision and eye care services in the United States. With more than 90,000 visits annually from a largely low-income, medically underserved patient population, IEI also provides charitable services and outreach programs to assist people in need, through its foundation.
