Our Doctors

Dr. Erica Burton


After graduating with honors from Northeastern State University, Dr. Burton joined her father, Dr. Gerald Swearingen, in practice in 1996. Dr. Burton was inducted into the NSU Hall of Fame and named Outstanding Senior of the Year.

Having served as President of the Southwest Missouri Optometric Society, Dr. Burton also dedicates time as a board member for the Missouri Optometric Association and is a former University of Missouri-St. Louis College of Optometry advisory board member. She currently enjoys traveling and speaking as a guest lecturer and educator at various events.

Dr. Burton cares for all ages and varied patient visual needs.  She provides outstanding medical eye care for her patients including care for dry eye, cataracts, diabetes, glaucoma, and macular degeneration. Specialty contact lens fitting including scleral contact lenses and myopia management are also areas of focus.  Dr. Burton is a provider for InfantSee, a national program that allows optometrists to give free eye examinations to babies less than one-year-old in order to detect and prevent future vision problems. 

Dr. Burton’s passion for taking care of her local community reaches further than providing excellent eye health and vision care. The Vision Solutions Reading Room provides use of devices to assist with reading as well as instruction on proper ways to use low vision aids. Additional services and initiatives available include vision therapy services to help with learning and post-concussion recovery, genetic testing for the best treatment options for eye diseases, and low-level light therapy for dry eye disease.  Many of these services cannot be found nearby.  This passion for her community has shown in awards such as Barton County Health Care Provider of the Year Awarded by Barton County Chamber of Commerce in 2018 and 2022.  

Dr. Burton currently sees patients at Vision Solutions in Lamar.

Dr. Burton enjoys spending time with her husband, Erick, and their two sons, Connor and Evan. She loves hiking and being involved with her local church.

Learn more about Dr Byergo’s path to excellence in optometry:
After getting my first glasses in 6th grade I could finally see again! I had no idea people could read the chalkboard or see leaves on trees. I needed glasses for years beforehand, but because I was a child, I was not equipped to express that myself. This is the case for the children I serve. Many teachers and parents don’t recognize their students are struggling until their school or sports performance seriously declines. Regular yearly eye exams with your optometrist are so important! I wish we had access to myopia management treatments at that time to prevent my vision from getting worse every year, which is why I am so happy to be able to offer this service to my young patients now.

I love when patients tell me they’ve never had a doctor be so thorough, explain things in a way they understand, or solve a problem they’ve had for years- even when they’ve been to the best specialists. I remember when I was new to the practice a patient told me with tears in their eyes how grateful they were to be able to see again after years of losing vision without a proper diagnosis from anyone else. Understanding patient education and meeting patient needs is my absolute priority. Moments like these make all my hard work worth it!

To provide excellent care in rural areas, Vision Solutions doesn’t specialize in just one area. We maximize what we provide to our patients with new technology and treatments because that is what our patients deserve. I provide expertise in a wide array of services because I can also understand the frustration of being referred to an unknown doctor hours away.

Dr. Byergo enjoys seeing all types and ages of patients in our Webb City and Nevada offices and is experienced in pediatrics, ocular disease, specialty contact lenses, and surgical co-management. He is passionate about Myopia Management to prevent children from losing vision and is focused on providing a lifetime of clear vision.

Dr. Byergo is currently accepting new patients of all ages in Webb City.

"It is so fulfilling to improve and challenge yourself, along with the support of your peers, to push Missouri optometry as a whole to new heights!"


Dr. Erin Mayfield


Raised in Lamar, Missouri, Dr. Erin Mayfield completed her undergraduate degree in biological sciences at the University of Missouri–Columbia. She then graduated with honors from the University of Missouri – St. Louis College of Optometry. While in optometry school, Dr. Mayfield was a student ambassador, as well as the president of the UMSL-College of Optometrists in Vision Development student chapter.

Dr. Mayfield has experience in all areas of optometry, including ocular disease management and contact lenses, but has a passion for pediatrics.

For example, Dr. Mayfield can prescribe Luminopia, a new virtual reality device used to treat amblyopia (lazy eye) in children. 

Dr. Mayfield recommends yearly eye health examinations, even if you don’t need glasses, in order to detect early changes in eye and systemic health. She and the staff at Vision Solutions are committed to performing high-quality eye care and helping you see your best. You can see Dr. Mayfield at our Lamar and Nevada locations.
