Who is Phernell Walker?
Phernell Walker is reshaping how opticians are educated and trained. As Chairperson of the American Board of Opticianry.
His signature achievement is the Pure Optics textbook, which has become the go-to resource for students preparing for ABO certification exams. But beyond the textbook, Phernell is an internationally sought-after speaker who brings complex optical concepts to life—making advanced material not just understandable, but genuinely compelling. His CE courses draw practitioners from around the world who appreciate his ability to connect theory with real-world practice.
Phernell's credentials reflect his commitment to excellence: an MBA and BS in Business provide strategic perspective, while dual certifications (ABOC, NCLEC) and his Washington LDO license ground him in clinical practice. Yet what truly sets him apart is his genuine passion for elevating the entire profession, through mentorship, education, and his influential work shaping industry standards.

Phernell's contributions to eye care education and the opticianry profession have earned him some of the industry's most prestigious honors. In 2017, he received both the Educator of the Year Award from the National Academy of Opticianry and the Joseph Bruneni Award in Optics from the Association of Schools and Colleges of Optometry, a recognition that speaks to his influence on how the next generation learns. Earlier, the Beverly Myers Achievement Award in Ophthalmic Optics (2011) acknowledged his pioneering work in advancing the field's knowledge and standards.
Beyond professional excellence, Phernell's humanitarian commitment has been recognized through the Helen Keller Benefactor Award (2019) from the Sight and Hearing Foundation in Oregon, honoring his dedicated work making ophthalmic optics education accessible and transformative for underserved communities.
Most recently, Phernell was honored by Silmo a Paris with a Special Recognition Lifetime Achievement Award (2024), a fitting tribute to a career defined by dedication, innovation, and the global transformation of opticianry education and service.
