Our Practice

The optometry practice of Dunlap Vision has been in existence for over 50 years. Drs. Long & Dunlap was established in 2004 when Dr. Dunlap bought the practice from Dr. Joe Long, who purchased the practice from Dr. Russell Rogers in 1982. After Dr. Long retired in 2011, Dr. Dunlap brought Dr. Lisa Jeziorny to the team & the Dunlap Vision team was born. 

After many years in practice, our office adheres to the same philosophy and goals. While accepting new patients from Kankakee,Bradley and Mantenoand, serving our established ones, we look ahead to the future by continually expanding our optometric education and diagnostic skills, investing in new technology, offering a huge inventory of modern frames and contact lenses, and utilizing a friendly, competent and dedicated staff to serve our communities and their visual needs.  We take pride in building lasting relationships with our patients which is why we take the time to get to know you, your vision requirements and your lifestyle.

We invite you to join our practice and receive the care that thousands of patients have enjoyed. Whether you have an eye infection, advanced eye disease, need laser vision correction, or a simple pair of glasses or contacts, we invite you to get the most reliable, professional vision care around. We want to become your family’s eye care practice for life.
