Darcy C. Ryan, O.D. has been practicing with the Hertzogs since 2000. He performs general and specialty exams on children (aged 7 and older) through adults, treats eye disease, and prescribes glasses (including prism correction for double vision), and most types of contact lenses (including silicone hydrogels, multifocals for those over 40yo, torics for astigmatism, and rigid gas permeables). This includes treating myopia (nearsightedness) in school-aged children. This is called Myopia Control or Myopia Management. This is a relatively new way to treat myopic children, and involves slowing down and stopping myopic progression to prevent potentially serious, vision-threatening eye diseases in adulthood. The sooner a child starts treatment, the less myopic they will ultimately become as an adult. Dr. Ryan is one of the only eye doctors in the Long Beach area performing myopia control/management on his pediatric patients.

Dr. Ryan grew up in the small town of Kirkland Lake in Northern Ontario, Canada. He completed his undergraduate studies at the University of Waterloo in Ontario, Canada, and then earned his Doctorate in Optometry from the Indiana University School of Optometry. His training included a 6-month rotation at the esteemed Bascom Palmer Eye Institute in Miami, FL, one of the top eye disease hospitals in the country.

Dr. Ryan and his lovely wife Brittney, who is a Speech Therapist, have 3 beautiful daughters who all love hockey just like their daddy. The Ryans are very happy to be part of the Hertzog Eye Care family.
