John Clark Jr., OD provides full-scope optometric care in Chula Vista through FirstSight Vision Services at 75 North Broadway along the city's western commercial corridor. His practice shares the Broadway Plaza retail hub with several health providers, and patients filling updated corrective-lens prescriptions can access the frame selection and lens-grinding services at Stanton Optical farther south on Broadway. Examination services include refraction for myopia, hyperopia, and astigmatism as well as binocular vision assessments and retinal evaluations. The office sits within the Costco-anchored H Street corridor, where acute ocular injuries after hours may redirect to AFC Urgent Care Chula Vista for triage before follow-up optometric management. Contact lens fittings cover spherical, toric, and multifocal designs calibrated with corneal topography measurements and tear-film stability testing.
