Dr. John C. Pack, OD co-founded Pack & Bianes Vision Care in Chula Vista's Eastlake corridor, operating from the Village Walk Medical Arts Center on Eastlake Parkway since the early 1990s. Sports-vision evaluations at the practice measure saccadic speed, vergence ranges, and peripheral-awareness thresholds, generating rehabilitation plans often coordinated with Performance Plus Physical Therapy - Otay Ranch for post-concussion athletes in the Eastlake area. A UC Irvine graduate and Southern California College of Optometry alumnus, the practitioner served as president of the San Diego County Optometric Association and received the California Optometric Association's Young Optometrist of the Year Award in 1999. The practice's Total Myopia program pairs orthokeratology lens fitting with low-dose atropine protocols, a dual-intervention approach that complements auditory-developmental screenings at Miracle-Ear Hearing Aid Center for pediatric patients presenting with combined sensory concerns. Specialty contact-lens fittings use corneal topography capturing over 22,000 elevation data points per scan to design custom scleral and gas-permeable lenses for keratoconus graded at Amsler-Krumeich stage II and above.
